Hands-On Network Programming with C# and .NET Core

By: Sean Burns

Overview of this book

The C# language and the .NET Core application framework provide the tools and patterns required to make the discipline of network programming as intuitive and enjoyable as any other aspect of C# programming. With the help of this book, you will discover how the C# language and the .NET Core framework make this possible. The book begins by introducing the core concepts of network programming, and what distinguishes this field of programming from other disciplines. After this, you will gain insights into concepts such as transport protocols, sockets and ports, and remote data streams, which will provide you with a holistic understanding of how network software fits into larger distributed systems. The book will also explore the intricacies of how network software is implemented in a more explicit context, by covering sockets, connection strategies such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP), asynchronous processing, and threads. You will then be able to work through code examples for TCP servers, web APIs served over HTTP, and a Secure Shell (SSH) client. By the end of this book, you will have a good understanding of the Open Systems Interconnection (OSI) network stack, the various communication protocols for that stack, and the skills that are essential to implement those protocols using the C# programming language and the .NET Core framework.

In this chapter, we took a thorough look at the WebRequest utility class, and how it can be used to handle a wide variety of common network operations within the context of a .NET application. We used the public interface of the class definition to infer the proper use and use cases for the class, as well as identifying the limits of its scope and operations. We considered the proper use and invocation of each of the public properties and methods defined on the base class, and wrote out some broadly applicable examples to demonstrate the simplicity and utility of the class and its children. Then, we considered the three most common concrete sub-classes of WebRequest. We examined some of the nuances between each of them and looked at how they facilitate the specific details of the protocols they were designed to operate over. Now we're ready to look at how to process...
