Socket实现客户端和服务器端的消息通信

例：编写一个控制台程序，利用同步Socket实现客户端和服务器端的消息通信。其中，服务器可以和多个客户端通信，并随时接收客户端发送的消息。

代码：clientSocket

 

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Net;using System.Net.Sockets;using System.Threading;namespace SocketClient1{ class Program { private static byte [] result = new byte [1024]; static void Main(string[] args) { //服务器ip地址 IPAddress ip = IPAddress.Parse("127.0.0.1"); Socket clientScoket = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp); try { clientScoket.Connect(new IPEndPoint(ip, 8889)); Console.WriteLine("连接服务器成功"); } catch { Console.WriteLine("连接服务器失败，请按回车退出。"); return; } //通过clientScoket接收数据 int receiveLength = clientScoket.Receive(result); Console.WriteLine("接收服务器消息:{0}",Encoding.ASCII.GetString(result,0,receiveLength)); //通过clientScoket发送数据 for (int i = 0; i < 10; i++) { try { Thread.Sleep(1000); string sendMessage = "client send message hello "+DateTime.Now; clientScoket.Send(Encoding.ASCII.GetBytes(sendMessage)); Console.WriteLine("向服务器发送消息：{0}",sendMessage); } catch { clientScoket.Shutdown(SocketShutdown.Both); clientScoket.Close(); break; } } Console.WriteLine("发送完毕，按回车键结束"); Console.ReadLine(); } }}

 

 

 

代码：serverSocket

 

 

 

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Net;using System.Net.Sockets;using System.Threading;namespace SocketServer{ class Program { private static byte[] result = new byte[1024]; private static int myprot = 8889; static Socket serverSocket; static void Main(string[] args) { //服务器ip地址 IPAddress ip = IPAddress.Parse("127.0.0.1"); serverSocket = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp); serverSocket.Bind(new IPEndPoint(ip,myprot)); serverSocket.Listen(10); Console.WriteLine("启动监听{0}成功",serverSocket.LocalEndPoint.ToString()); //通过clientsocket发送来的数据 Thread myThread = new Thread(ListenClientConnect); myThread.Start(); Console.ReadLine(); } private static void ListenClientConnect() { while (true) { Socket clientsocket = serverSocket.Accept(); clientsocket.Send(Encoding.ASCII.GetBytes("server say hello")); Thread receiveThread = new Thread(ReceiveMessage); receiveThread.Start(clientsocket); } } private static void ReceiveMessage(Object clientSocket) { Socket myClientSocket = (Socket)clientSocket; while (true) { try { //通过clientsocket接收数据 int receiveNumber = myClientSocket.Receive(result); Console.WriteLine("接收客户端{0}消息{1}",myClientSocket.RemoteEndPoint,Encoding.ASCII.GetString(result,0,receiveNumber)); } catch(Exception e) { Console.WriteLine(e.Message); myClientSocket.Shutdown(SocketShutdown.Both); myClientSocket.Close(); break; } } } }}
