1、//Socket基本编程//服务端：usingSystem.Net;usingSystem.Net.Sockets;usingSystem.Text;usingSystem.Threading;Threadmythread;Socketsocket;//清理所有正在使用的资源。protectedoverridevoidDispose(booldisposing){try　{　　　　socket.Close();//释放资源　　mythread.Abort();//中止线程　}　catch{}if(disposing){if(components!=

2、null){components.Dispose();}}base.Dispose(disposing);}publicstaticIPAddressGetServerIP(){IPHostEntryieh=Dns.GetHostByName(Dns.GetHostName());returnieh.AddressList[0];}privatevoidBeginListen(){IPAddressServerIp=GetServerIP();IPEndPointiep=newIPEndPoint(ServerIp,8000);socket=new

3、Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);byte[]byteMessage=newbyte[100];this.label1.Text=iep.ToString();socket.Bind(iep);//dowhile(true){try{socket.Listen(5);SocketnewSocket=socket.Accept();newSocket.Receive(byteMessage);stringsTime=DateTime.Now.To

4、ShortTimeString();stringmsg=sTime+":"+"Messagefrom:";msg+=newSocket.RemoteEndPoint.ToString()+Encoding.Default.GetString(byteMessage);this.listBox1.Items.Add(msg);}catch(SocketExceptionex){this.label1.Text+=ex.ToString();}}//while(byteMessage!=null);}//开始监听privatevoidbutton1_C

5、lick(objectsender,System.EventArgse){try{mythread=newThread(newThreadStart(BeginListen));mythread.Start();}catch(System.Exceptioner){MessageBox.Show(er.Message,"完成",MessageBoxButtons.OK,MessageBoxIcon.Stop);}}//客户端：usingSystem.Net;usingSystem.Net.Sockets;usingSystem.Text;priva
