C#TCP通讯(一)

服务端代码

TcpListener tcpListener=new TcpListener(IPAddress.Parse("192.168.1.1"),9000);

tcpListener.Start();//启动服务

While(true)

{

TcpClient tcpClient=tcpListener.AcceptTCPClient();//收到链接

NetWorkStream steam=tcpClient.GetStream();

byte[] receiveData=new byte[1024];

var len=stream.Read(receiveData,0,1024);

string receiveString=Encoding.UTF8.GetString(receiveData,0,len);//字节数据解析成字符串

string sendString="收到信息";

var sendData=Encoding.UTF8.GetBytes(sendString);

stream.Write(sendData,0,sendData.Length);//向客户端发送信息

}

 

客户端代码

TCPClient tcpClient=new TCPClient();

tcpClient.Connect("192.168.1.1",9000);

NetWorkStream steam=tcpClient.GetStream();

string sendString="请求消息";

var sendData=Encoding.UTF8.GetBytes(sendString);

steam.Write(sendData,0,sendData.Length);//向服务端发送消息

byte[] receiveData=new byte[1024];

var len=stream.Read(receiveData,0,1024);

var receiveString=Encoding.UTF8.GetString(receiveData,0,len);//将接收服务端返回的字节解析成字符串

tcpClient.Close();

tcpClient.Dispose();
