Microsoft .NET is an advance in programming technology that greatly simplifies application development, both for traditional, proprietary applications and for the emerging paradigm of Web-based services. .NET 6 is a unified platform, for browser, cloud, desktop, IoT, and mobile apps. It is based on .NET Core, the package-based implementation that is cross-platform, running on Mac and Linux besides Windows. It completes the unification of the .NET platform begun with .NET 5.
Part of this technology is the new language from Microsoft, C#. This language combines the power of C++ and the ease of development of Visual Basic 6. It bears a striking resemblance to Java and improves on that language. C# has become the dominant language for building new applications on Microsoft platforms.
This thorough and comprehensive course is a practical introduction to programming in C#, utilizing the services provided by .NET. This course emphasizes the C# language. It is current to Visual Studio 2022, .NET 6 and C# 10. Important newer features such as dynamic data types, named and optional arguments, tuples, asynchronous programming keywords, nullable reference types, record types, and top-level statements are covered. Supplements provide a tutorial on Visual Studio 2022, an overview of LINQ, and coverage of unsafe code and pointers in C#.
This course is intended to be fully accessible to programmers who do not already have a strong background in object-oriented programming in C-like languages, such as C++ or Java. It is ideal, for example, for procedural programmers who desire to learn C#.
An important thrust of the course is to teach C# programming from an object-oriented perspective. It is often difficult for programmers trained originally in a procedural language to start “thinking in objects.” This course introduces object-oriented concepts early, and C# is developed in a way that leverages its object orientation. A case study is used to illustrate creating a complete system using C# and .NET. Besides supporting traditional object-oriented features, such as classes, inheritance, and polymorphism, C# introduces several additional features, such as properties, indexers, delegates, events, and interfaces that make C# a compelling language for developing object-oriented and component-based systems. This course provides thorough coverage of all these features.
C# as a language is elegant and powerful. But to utilize its capabilities fully, you need to have a good understanding of how it works with the .NET Framework. The course explores several important interactions between C# and the .NET Framework, and it includes an introduction to major classes for collections, delegates, and events. It includes a succinct introduction to creating GUI programs using Windows Forms. The course concludes with a chapter covering the newer features in the language.
Numerous programming examples and exercises are provided, including the case study. The student will receive a comprehensive set of materials, including course notes and all the programming examples.

• The student should have programming experience in a high-level language. This course is intended to be fully accessible to programmers who do not already have a strong background in object-oriented programming in C-like languages, such as C++ or Java. It is ideal, for example, for procedural programmers who desire to learn C#.
This course is taught by a live instructor and is available in two class formats:
Data types are an important concept in C# programming. They define the type of data that a variable can contain, such as integers, strings, or booleans. In C#, there are two main types of data: Value Types and Reference Types.
Value Types are simple data types that have values assigned directly to them. Examples of Value Types include integers, floats, booleans, and characters. Value Types are allocated on the stack, meaning that their values exist only for as long as the program is running.
Reference Types are types that store a reference to their data instead of the actual value itself. These references point to data stored in memory off of the stack, meaning they can exist independently of the program’s execution. Examples of Reference Types include strings, objects, delegates, and arrays.
Data types are important to C# programming because they give structure to a programming language, allowing you to assign variables in an organized manner. They also help maintain consistency throughout your code by ensuring that each variable contains the correct data type. It is important to understand what types of data are available and how they interact with each other to write efficient and bug-free code. Using incorrect or incompatible data types can lead to errors, which can be difficult to diagnose and rectify. By understanding the different types of data available in C#, you can maximize the utility of your code.
C# operators are symbols that are used to perform operations on one or more operands. They can be used in expressions to manipulate the values of variables, constants, and literals. Common operators include arithmetic (+, -, *, /), comparison (==, != , >, <) and logical (&& , ||).
Expressions are combinations of operators and operands that evaluate a single value. They can be used in statements, such as control flow statements (if, else) or looping constructs (for, while). Expressions can also be used to assign values to variables or constants.
Knowing how to properly use C# operators and expressions is an important skill for any programmer. It is important to understand the precedence rules for evaluating operators to ensure that expressions are evaluated correctly and produce the expected result. It is good practice to use parentheses to group operators and operands within an expression so that evaluation progresses from left to right instead of relying on operator precedence.
By properly utilizing C# operators and expressions, developers can write more powerful code that is easier to read and maintain. They are useful tools for creating functions, solving equations, manipulating data, and much more. Knowing how to use them properly will help any programmer become even better at their craft.
C# Control Structures are a set of instructions that provide the control flow for C# programs. This is done by using selection, iteration, and jump statements. Selection statements allow code execution to choose one path or another depending on certain conditions, such as a Boolean expression that evaluates to either true or false. Iteration statements enable instructions to be repeated several times, allowing for looping mechanisms such as for loops and while loops. Jump statements allow the program to jump over certain lines of code, bypassing them to go straight to another statement in the program.
By using these control structures, programming logic can be efficiently organized and implemented. Control Structures are an important part of C# programming and are essential for creating effective applications. It is important to understand the different types of control structures and how they work to write powerful and efficient code. With the right knowledge and practice, developers can be sure to create robust solutions that are highly performant.
C# Object-Oriented Programming (OOP) is a programming language model based on the concept of objects, or data structures that contain both data and functionality. It relies heavily on inheritance and encapsulation to create objects that can interact with each other in an organized manner. OOP allows for code to be reused by creating classes which define the behavior of objects, making it easier to build complex applications. By creating interacting objects, developers can divide up tasks and tackle each one separately, resulting in an organized and efficient program.
C# is a powerful language that enables developers to create robust and secure programs quickly and efficiently. With its object-oriented approach, C# helps developers build scalable and maintainable applications that are flexible and can easily be adjusted to changing business needs. In addition, C# makes it easier for developers to build complex graphical user interfaces (GUIs) with the Windows Forms library. By leveraging the full power of its object-oriented features, C# helps developers create highly efficient and secure applications that are both powerful and easy to use.
C# classes are used to define the structure of an object. They contain data and methods that can be used to manipulate the data. C# classes provide a blueprint for creating objects with predefined properties and behaviors, making them one of the most powerful features of C# development. By utilizing C# classes, developers are able to create complex applications quickly and easily. Classes help developers organize their code, improve readability, and save time by avoiding the need to rewrite code that has already been written.
C# classes are a cornerstone of object-oriented programming and are essential for any serious software development project. By utilizing C# classes, developers can create objects with distinct characteristics while also reducing complexity and minimizing the time needed to complete development projects.
C# is a statically-typed language, meaning that the type of an object must be known when it is created. There are two main types in C#: value types and reference types.
Value Types are simple data elements such as ints, floats, bools, and chars. They are stored directly on the stack and do not require any additional memory allocation. These types are also immutable, meaning they cannot be changed once they have been created.
Reference Types are used to store complex data or reference other objects in memory. Reference types such as classes, structs, and strings are stored on the managed heap and require additional memory allocation. These types are also mutable, meaning they can be changed at any time.
Boxing and Unboxing allow the conversion of a value type to an object type and vice versa. Boxing is the process of converting a value type into an object, while unboxing is converting an object back into a value type. This process can be useful when working with collections of objects or when passing values to functions that require objects.
Implicitly Typed Variables are variables that have a type inferred from the initial value assigned to them. This allows for more concise code and makes it easier to work with complex data types. It is important to note that implicitly typed variables must be initialized before they can be used.
C# provides many different types that enable developers to work with data effectively. Understanding the distinctions between value types and reference types, as well as how to use boxing and unboxing and implicitly typed variables, are essential for working with C#.
C# methods, properties, and operators are important components of the C# programming language. They allow developers to build robust and scalable applications by providing a reusable set of instructions for manipulating data and performing operations on that data.
Methods are blocks of code that can be used to perform an action or produce a value; properties define values associated with an object, such as its size or color; and operators allow developers to carry out mathematical operations on values, such as addition or subtraction. Together, they provide an essential building block in the construction of any C# program. Developers should have a solid understanding of each of these components to create efficient code that meets the desired requirements. When used in conjunction with other language features, they can help developers create applications that are both powerful and reliable.
With thorough knowledge of methods, properties, and operators, developers can create robust software solutions that meet the needs of their users. Understanding these concepts is essential for anyone looking to become proficient in C# programming.
C# characters and strings are data types used to store and manipulate text within an application. Characters are stored as single characters, while strings can contain multiple characters. C# makes it easy to create and manipulate strings by providing a wide variety of methods for string manipulation. Strings in C# are immutable, meaning that once created, they cannot be changed. This makes strings efficient and secure, as they are not vulnerable to accidental changes made by the program code. C# also provides a rich set of library functions that can be used to manipulate strings in useful ways. For example, you can use library functions to search for substrings within a string, convert strings between different formats, trim whitespace from the ends of a string, and many other operations. Strings can also be combined with other data types to create complex data structures such as arrays, lists, dictionaries, and so on. With C#, you can easily manipulate strings in powerful ways to achieve the desired results. Utilizing C#'s vast library functions is key to getting the most out of your string manipulation operations.
C# strings are a powerful tool for storing and manipulating textual data in applications. C# also provides a range of features that allow developers to create robust and secure programs with minimal effort. These features include built-in methods such as ToUpper() or Replace(), as well as many more advanced features. With the vast range of functions at your disposal, you can easily manipulate strings in creative and powerful ways to achieve your desired results. By taking advantage of C#'s string manipulation capabilities, you can create applications that are both efficient and secure.
C# characters and strings are a vital part of many applications and are used to store, manipulate and display text data. C# provides a wide range of functions that make it easy to create powerful and secure programs with minimal effort. By utilizing the built-in library functions, developers can easily manipulate strings in creative ways to achieve their desired results. With the right usage of these features, you can create robust and secure applications with ease.
C# arrays and indexers are data structures that store multiple elements of the same type in a contiguous memory address. Indexers provide an easy way to access array elements without having to use a loop or hard-code numeric indices. The .NET Framework includes built-in support for dynamically resizing arrays and provides range checking when accessing array indices, ensuring that any access to out-of-range elements will throw an exception and prevent the application from crashing. C# arrays also include methods for manipulating their contents, such as sorting and searching. They provide a thread-safe way to share data across multiple threads of execution. With these features and more, C# arrays offer a powerful tool for storing and manipulating data.
C# arrays are an invaluable tool for developers and can be used to store data efficiently and manipulate it easily. With built-in support for dynamic resizing, range checking, thread safety, and more, they offer a powerful way of working with data in your applications. In addition, indexers make it easy to access and manipulate individual elements within the array. With a little practice, developers will find C# arrays to be an invaluable tool in their programming arsenal.
C# inheritance is an object-oriented programming (OOP) feature that allows a class to be based on another existing class. This enables the new class, referred to as a derived class, to inherit field and method declarations from the parent, or base, class. In other words, the derived class acts as if it contains all of the members (fields and methods) of the base class. C# inheritance provides a powerful way to reuse existing code by allowing new classes to be derived from existing ones, thus saving time and effort in developing software applications. It also allows for better organization of source code, as related classes can be grouped logically. Moreover, it promotes polymorphism which allows for different objects to respond differently to the same method call. C# inheritance is a convenient and effective way of reusing code, improving organization, and achieving polymorphism in software development.
C# inheritance relies on the concept of encapsulation which allows data fields and methods of an object to be hidden from external access so that only authorized entities can modify them. This ensures that the object and its data remain intact, making it easier for developers to create secure applications. C# inheritance allows classes to be organized into a hierarchy which makes it easier to navigate complex code structures and identify relationships between objects. This hierarchical structure also helps with debugging since errors in parent classes automatically carry over to the derived classes.
C# inheritance is a powerful tool for software development. It enables developers to reuse existing code, improve the organization of source code, and accommodate polymorphism in their applications. It ensures that data fields and methods remain secure from external access via encapsulation, and facilitates easy navigation of complex code structures through their hierarchical structure. Utilizing C# inheritance can save developers time and effort, and result in better-quality applications.
C# virtual methods and polymorphism are key components of object-oriented programming. Virtual methods allow the programmer to define a base class with virtual functions and then allow derived classes to override the behavior of those functions without changing the underlying code. This facilitates a great degree of code reuse which is especially useful when working on large projects. Polymorphism extends this idea by allowing the same code to be used for objects of different types. Instead of having to write separate functions for each type, a single function can be written which will work on any object that implements the correct interface. This makes code much more maintainable and easier to debug. Both virtual methods and polymorphism are essential concepts for anyone wanting to learn object-oriented programming in C#.
C# formatting and conversion is a process of changing the appearance or representation of data. This can be done to improve readability, create uniformity between disparate data sources, or as part of a software development project. It is an incredibly versatile tool that developers use to make sure their programs work properly by converting data from one format into another. C# formatting and conversion tools are often used to change the format of text, numbers, dates, and other types of data into a form that can be read or understood by computers. With these tools, developers can create programs that effectively handle any type of data in whatever format it may take. They also can make sure that data is presented to users in a way that is easy to understand, efficient, and secure.
C# formatting and conversion tools are invaluable for developers who need to create programs that can interact with data from any source. By providing the necessary tools, these developers can make sure their programs work properly, regardless of what type of data is being processed. With the right formatting and conversion tools, developers can have confidence that their programs will run reliably, securely, and effectively.
C# exceptions are errors that occur during the execution of a program. These errors cause the code to terminate abruptly, stopping any further processing or operation from occurring. C# exceptions are generated when an unexpected event occurs and can include things such as system failure, invalid input/output data, memory problems, etc. Some user-defined exceptions can be used to create custom errors or warnings. Handling these exceptions appropriately is essential for making sure a program runs smoothly and efficiently. C# provides a range of tools and techniques, such as try-catch statements, that developers can use to properly handle exceptions in their code. This will help ensure that any unexpected errors are effectively managed and that the program does not crash. Proper error handling will also help developers identify potential bugs in their code and make sure that any issues are managed quickly and appropriately.
By understanding C# exceptions and their associated techniques, developers can create stable, reliable programs that perform optimally for the user. With proper exception-handling practices, developers can ensure that their programs can anticipate and manage unexpected events with confidence. This will help promote a better user experience overall, providing them with the quality software they deserve.
C# interfaces are a powerful tool for developers to create and implement contracts. An interface is an abstract type that contains only the signatures of methods, properties, events, or indexers. It can be used as a contract between classes and it provides a way to decouple objects from each other. Interfaces are also useful in providing multiple inheritance which allows a class to inherit behavior from multiple base classes. By using interfaces, developers can easily develop and maintain code as they can use it to ensure that any type that implements an interface must adhere to the contract specified by the interface. Interfaces are also useful for creating loosely coupled applications that allow different components of a system to interact without relying on one another. This increases the reusability of code and makes it easier to maintain different components. Interfaces provide a great way to perform polymorphic behavior by allowing developers to create objects that share the same interface but may have different implementations.
.NET Interfaces and Collections are data structures that allow developers to store, organize and manipulate data efficiently. They provide the ability to maintain the robustness of code while increasing its performance. Interfaces offer a contract between two objects, such as classes, components, or other services. Collections ensure the most effective management and manipulation of information within the system. They allow developers to store data in arrays, lists, or dictionaries, as well as create customized collections tailored specifically for their application. .NET Interfaces and Collections are essential tools for development teams who want to build reliable and performant applications quickly and efficiently. They enable developers to easily access, manage and manipulate data, ensuring that applications are scalable and maintainable for a long period. By leveraging the power of .NET Interfaces and Collections, developers can achieve higher levels of productivity and performance.
C# delegates and events are two important concepts in the development of applications. Delegates are a type of object that can be used to pass methods as parameters, allowing for better code organization and extensibility. Events are a way for objects to communicate with each other without the use of direct method calls.
Delegates allow developers to pass functions or methods as parameters instead of objects. This allows for better abstraction and code organization since the same function can be reused across different classes with varying parameters. It also makes it easier to extend an existing application by adding new methods without having to modify the existing codebase.
Events are a type of notification system that allows objects to communicate with each other without requiring direct method calls. When an event is triggered, it notifies any object that has subscribed to the notification so they can take the appropriate action. This allows for better resource management since objects are only notified when an event occurs rather than repeatedly checking if something has changed.
C# delegates and events provide developers with a powerful way to create more efficient, extensible applications. By taking advantage of these tools, developers can develop better software faster and with fewer bugs.
Windows Forms with C# is a powerful Windows-based application development framework. It provides developers with the tools needed to quickly and efficiently create graphical user interfaces (GUIs) for their applications. The use of C# in this development pool allows developers to take advantage of the language's object-oriented programming capabilities, which makes it easier to code more complex and feature-rich user interfaces. With Windows Forms, developers can create dynamic panels, data grids, menus, dialog boxes, toolbars, and more to provide users with the best possible experience when using their applications. Windows Forms with C# supports a range of other features such as drag-and-drop components, animation control, and event handling that further enhance the user experience. With Windows Forms, developers can create high-quality GUIs with minimal coding and a rapid development time. This makes it an ideal choice for developing Windows applications.
