C#实现Socket通信的解决方法

本文以实例详述了c#实现socket通信的解决方法，具体实现步骤如下：

1、首先打开vs新建两个控制台应用程序：
consoleapplication_socketserver和consoleapplication_socketclient。
 
2、在consoleapplication_socketclient中输入以下代码：

using system; 
using system.collections.generic; 
using system.linq; 
using system.text; 
using system.net; 
using system.net.sockets; 
 
namespace consoleapplication_socketclient 
{ 
  class program 
  { 
    static socket clientsocket; 
    static void main(string[] args) 
    { 
      //将网络端点表示为ip地址和端口 用于socket侦听时绑定  
      ipendpoint ipep = new ipendpoint(ipaddress.parse("*.*.*.*"), 3001); //填写自己电脑的ip或者其他电脑的ip，如果是其他电脑ip的话需将consoleapplication_socketserver工程放在对应的电脑上。 
      clientsocket = new socket(ipep.addressfamily,sockettype.stream,protocoltype.tcp);  
      //将socket连接到服务器  
      try 
      { 
        clientsocket.connect(ipep); 
        string outbufferstr; 
        byte[] outbuffer = new byte[1024]; 
        byte[] inbuffer = new byte[1024]; 
        while (true) 
        { 
          //发送消息  
          outbufferstr = console.readline(); 
          outbuffer = encoding.ascii.getbytes(outbufferstr); 
          clientsocket.send(outbuffer, outbuffer.length, socketflags.none); 
           
          //接收服务器端信息        
          clientsocket.receive(inbuffer, 1024, socketflags.none);//如果接收的消息为空 阻塞 当前循环 
          console.writeline("服务器说："); 
          console.writeline(encoding.ascii.getstring(inbuffer)); 
        } 
      } 
      catch 
      { 
        console.writeline("服务未开启！"); 
        console.readline(); 
      } 
    } 
  } 
}

3、在consoleapplication_socketserver中输入以下代码：

using system; 
using system.collections.generic; 
using system.linq; 
using system.text; 
using system.io; 
using system.net; 
using system.net.sockets; 
using system.threading; 
 
namespace consoleapplication_socketserver 
{ 
  class program 
  { 
    static socket serversocket; 
    static socket clientsocket; 
    static thread thread; 
    static void main(string[] args) 
    { 
      ipendpoint ipep = new ipendpoint(ipaddress.any, 3001); 
      serversocket = new socket(ipep.addressfamily, sockettype.stream, protocoltype.tcp); 
      serversocket.bind(ipep); 
      serversocket.listen(10); 
      while (true) 
      { 
        clientsocket = serversocket.accept(); 
        thread = new thread(new threadstart(dowork)); 
        thread.start(); 
      } 
    } 
    private static void dowork() 
    { 
      socket s = clientsocket;//客户端信息 
      ipendpoint ipendpoint = (ipendpoint)s.remoteendpoint; 
      string address = ipendpoint.address.tostring(); 
      string port = ipendpoint.port.tostring(); 
      console.writeline(address + ":" + port + " 连接过来了"); 
      byte[] inbuffer = new byte[1024]; 
      byte[] outbuffer = new byte[1024]; 
      string inbufferstr; 
      string outbufferstr; 
      try 
      { 
        while (true) 
        { 
          s.receive(inbuffer, 1024, socketflags.none);//如果接收的消息为空 阻塞 当前循环 
          inbufferstr = encoding.ascii.getstring(inbuffer); 
          console.writeline(address + ":" + port + "说:"); 
          console.writeline(inbufferstr); 
          outbufferstr = console.readline(); 
          outbuffer = encoding.ascii.getbytes(outbufferstr); 
          s.send(outbuffer, outbuffer.length, socketflags.none); 
        } 
      } 
      catch 
      { 
        console.writeline("客户端已关闭！"); 
      } 
    } 
  } 
}

4、先运行consoleapplication_socketserver，后运行consoleapplication_socketclient就可以通信了。

本例给出了基本的实现代码，读者可以根据自身的需求进一步完成个性化功能。
