本文实例讲述了C#简单聊天程序实现方法。分享给大家供大家参考。具体如下：

假如有服务器端程序,ChatServer和客户端程序ChatClient.实现客户端向服务器端发送信息的简单功能.

运行步骤,

1.先是服务器端start listen,

2.然后客户端connect.

3.客户端发送消息

只要服务器端start listen了,然后客户端也connect了.这样建立起连接后.接受发送信息就方便了,只要用writer,reader去操作NetworkStream

服务器ChatServer

创建一个WinForm页面

引用命名空间:

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); }

客户端ChatClient

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server private 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(); }

希望本文所述对大家的C#程序设计有所帮助。
