C#通過Socket實現客戶端和服務器端通信的簡單例子

C#通過Socket實現客戶端和服務器端通信的簡單例子
下面的代碼演示了如果創建一個用于在客戶端和服務端交換信息的代碼Socket Server 服務器端

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();
             }

             clientSocket.Send (Encoding.Unicode.GetBytes ("You there?!!!!"));
