C#通过Socket实现客户端和服务器端通信的简单例子

C#通过Socket实现客户端和服务器端通信的简单例子
下面的代码演示了如果创建一个用于在客户端和服务端交换信息的代码Socket Server 服务器端

using System;
using System.Collections.Generic;
using System.Text;
using System.Net.Sockets;
using System.Net;
 
namespace ConsoleApplication1
 {
     Class Program
     {
         static void Main (String[] args)
         {
             // 1. to create a socket
             Socket sListen = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
 
             / / 2. Fill IP
             IPAddress IP = IPAddress.Parse ("127.0.0.1");
             IPEndPoint IPE = new IPEndPoint (IP, 4321);
 
             / / 3. binding
             sListen.Bind (IPE);
 
             / / 4. Monitoring
             sListen.Listen (2);
 
             / / 5. loop to accept client connection requests
             while (true)
             {
                 Socket clientSocket;
                 try
                 {
                     clientSocket = sListen.Accept();
                 }
                 catch
                 {
                     throw;
                 }
                 // send data to the client
                 clientSocket.Send (Encoding.Unicode.GetBytes ("You there?!!!!"));
             }
         }
 
     }
 }

             Console.WriteLine("Start to connect to server ....");
             s.Connect (IPE);
