C#实现简单聊天程序的方法
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startlisten,
2.然后客户端connect.
3.客户端发送消息
只要服务器端startlisten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:
usingSystem.Net.Sockets;
usingSystem.Net;
usingSystem.IO;
usingSystem.Threading;
publicclassChatServer
{
privateintport=54321;//端口号
privateIPAddressip=IPAddress.Parse("10.20.30.40");//ip地址
privateTcpListenertcpListener=null;
privateTcpClienttcpClient=null;
privateNetworkStreamnetworkStream=null;
privateBinaryReaderreader;
//privateBinaryWriterwriter;
privatestringgetInfo=string.empty;
//开始监听
privatevoidbtnStartListen_Click(objectsender,EventArgse)
{
tcpListener=newTcpListener(ip,port);
tcpListener.Start();//开始监听
ThreadacceptClientMsgThread=newThread(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
privatevoidAcceptClientMsg()
{
tcpClient=tcpListener.AcceptTcpClient();
if(tcpClient!=null)
{
networkStream=tcpClient.GetStream();
reader=newBinaryReader(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
//stringsendMsg=txtSendMsge.Text;
//writer=newBinaryWriter(networkStream);
//writer.write(sendMsg);
}
客户端ChatClient
usingSystem.Net.Sockets;
usingSystem.Net;
usingSystem.IO;
usingSystem.Threading;
publicclassChatClient
{
privateintport=54321;
privateIPAddressip=IPAddress.Parse("10.20.30.40");
privateTcpClienttcpClient=null;
privateNetworkStreamnetworkStream=null;
//privateBinaryReaderreader;
privateBinaryWriterwriter;
//连接server
privatevoidbtnStartConnect_Click(objectsender,EventArgse)
{
tcpClient=newTcpClient();
tcpClient.Connect(ip,port);
networkStream=tcpClient.GetStream();
}
//发送信息
privatevoidbtnStartConnect_Click(objectsender,EventArgse)
{
stringsendMsg=txtSendMsg.Text;
writer=newBinaryWriter(networkStream);
writer.Write(sendMsg);//发送信息
}
//如果还要接受server的消息的话.
//reader=newBinaryReader(networkStream);
//stringgetInfo=reader.ReadString();
}
希望本文所述对大家的C#程序设计有所帮助。
