This article mainly introduces "what are the basic knowledge of the introduction to C# network programming". In the daily operation, I believe that many people have doubts about the basic knowledge of the introduction to C# network programming. I have consulted all kinds of materials and sorted out the simple and easy-to-use operation methods. I hope it will be helpful for you to answer the questions about "what are the basic knowledge of the introduction to C# network programming?" Next, please follow the editor to study!

What are the basics of getting started with network programming in C #? Let's take a look: we know that one of the differences between C # and C++ is that it does not have a class library itself, and the class library used is the class library in the .net framework-.Net FrameWork SDK. Two namespaces are provided for network programming in .net FrameWork SDK: "System.Net" and "System.Net.Sockets". C # realizes network communication through the classes and methods encapsulated in these two namespaces.

First of all, let's explain a few concepts that we often encounter in network programming: synchronous, asynchronous, Block, and Unblock:

The synchronization method of the introduction to C# Network programming

That is, after the sender sends the packet, it continues to send the next packet without waiting for the receiver to respond.

The Asynchronous Mode of getting started with C # Network programming

When the sender sends a packet, it waits until the receiver responds before sending the next packet.

C # getting started with network programming blocking socket

This means that when a network call to this socket is executed, it will not return until the call succeeds, otherwise the socket will always block the network call, such as calling the Readlin () method of the StreamReader class to read the data in the network buffer. If no data arrives at the time of the call, the Readlin () method will hang on the call until some data is read before the function call returns.

Introduction to C # Network programming non-blocking socket

Means that when a network call to this socket is made, it is returned immediately, regardless of whether the execution is successful or not. Also call the Readlin () method of the StreamReader class to read the data in the network buffer and return immediately regardless of whether the data is read or not, instead of hanging on this function call. In the development of Windows network communication software, the most commonly used method is asynchronous non-blocking socket. The so-called Cramp S (client / server) structure of the software is asynchronous non-blocking mode.

In fact, in network programming with C #, we do not need to understand the principles and working mechanisms of synchronization, asynchronism, blocking and non-blocking, because these mechanisms have been encapsulated in .net FrameWrok SDK.

At this point, the study of "what are the basic knowledge of C# network programming" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
