C#实现简单聊天程序的方法

using System.Net.Sockets;using System.Net;using System.IO;using System.Threading;public class ChatServer{private int port = 54321; //端口号private IPAddress ip = IPAddress.Parse("10.20.30.40"); //ip地址private TcpListener tcpListener= null;private TcpClient tcpClient = null;private NetworkStream networkStream = null;private BinaryReader reader;//private BinaryWriter writer;private string getInfo = string.empty;//开始监听private void btnStartListen_Click(object sender, EventArgs e){   tcpListener= new TcpListener( ip , port);   tcpListener.Start(); //开始监听   Thread acceptClientMsgThread= new Thread(AcceptClientMsg);   //运行一个线程去处理客户端发来的信息   acceptClientMsgThread.Start();}//处理客户端发来的信息private void AcceptClientMsg() {  tcpClient = tcpListener.AcceptTcpClient();  if( tcpClient != null)  {    networkStream = tcpClient.GetStream();    reader = new BinaryReader( networkStream);    while (true){     getInfo += reader.ReadString();  //读取客户端发来的信息    }  }}//假如还要显示信息的话,可以整个显示按钮(当然最好的办法是用些线程)//然后点击button后让信息显示出来txtShowClientMsg.Text = getInfo;//如果服务器端想再给客户端发信息,就可以整个发送按钮.然后添加如下代码//string sendMsg = txtSendMsge.Text;//writer = new BinaryWriter( networkStream);//writer.write( sendMsg);}

using System.Net.Sockets;using System.Net;using System.IO;using System.Threading;public class ChatClient{ private int port = 54321;private IPAddress ip = IPAddress.Parse("10.20.30.40");private TcpClient tcpClient = null;private NetworkStream networkStream = null;//private BinaryReader reader;private BinaryWriter writer;//连接serverprivate void btnStartConnect_Click(object sender, EventArgs e){ tcpClient = new TcpClient(); tcpClient.Connect( ip, port); networkStream = tcpClient.GetStream();}//发送信息private void btnStartConnect_Click(object sender, EventArgs e){ string sendMsg = txtSendMsg.Text; writer = new BinaryWriter( networkStream); writer.Write( sendMsg); //发送信息}//如果还要接受server的消息的话.//reader = new BinaryReader( networkStream);//string getInfo = reader.ReadString();}
