three. Part of the C # Network programming server-side program: Server.cs): Since the structure we use in this program is an asynchronous blocking method, in the actual program, in order not to affect the running speed of the server-side program, we A thread is designed in the program so that the network requests listening, accepting, and sending data are handled in the thread. Please pay attention to this in the code below. Here is the full code of Server.cs: use system; use system.
