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(); }
