C#实现简单聊天程序的方法

来源：http://www.jb51.net/article/67316.htm

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

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

privatevoid 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);

}
