 一、TCP通讯（服务端）

二、控件展示

 三、TCP 服务端 客户端 分辨

四、控件解析

一般IP地址本机都是 ：  127.0.0.1

端口号会有显示：   60000

服务端：  启动监听  停止监听      都会有发送信息

服务端对接的是客户端  可以理解为是理解

控件：ListBox  是为了更好展示运行的过程

五、链接控件实施

1.实例化三个Socket

 public Socket ServerSocket {  get; set; }public Socket SocketAccept { get; set; }public Socket socket;

 ServerSocket  是用来套接字   用来监听的套子节

SocketAccept  是用来接收绑定客户端的套接字

2.过程运行结果，展示

 private void Showmsg(string s){listBox1.BeginInvoke(new Action<string>(str =>{listBox1.Items.Add(str);}), s);}

注意： 由于在线程中，分线程不能操作ui界面，所以需要用Invoke来调用

或者：  CheckForIllegalCrossThreadCalls=false;   对非法线程调用不进行检测

3.线程，开始监听事件

  Thread t1;Thread t2;

4.按钮一：启动监听实施

 private void btnstart_Click(object sender, EventArgs e){btnstart.Enabled=false;btncancel.Enabled=true;ServerSocket=new Socket(AddressFamily.InterNetwork,SocketType.Stream, ProtocolType.Tcp);//绑定ip地址IPAddress iPAddress=IPAddress.Parse(textBox1.Text);//绑定端口号int port=int.Parse(textBox2.Text);//建立连接IPEndPoint iPEndPoint=new IPEndPoint(iPAddress, port);try{//绑定连接点ServerSocket.Bind(iPEndPoint);//开始监听ServerSocket.Listen(5);t1 = new Thread(ListenT1);t1.IsBackground=true;t1.Start(ServerSocket);}catch (Exception ex){throw;}}private void ListenT1(object o){SocketAccept = o as Socket;try{while(true){       //线程阻塞,直到有客户连接,再去执行后续代码socket = SocketAccept.Accept();Showmasg($"{DateTime.Now.ToString("HH-mm-ss")}{socket.RemoteEndPoint}连接成功");t2 = new Thread(Received);t2.IsBackground=true;t2.Start(socket);}}catch (Exception ex){throw;}}private void Received(object o){socket=o as Socket;//传递的数据大小为2Mbyte[]buffer=new byte[1024*1024*2];int r=socket.Receive(buffer);if (r==0){return;}string s=Encoding.UTF8.GetString(buffer);Showmasg(s);}

代码解释：

实例化一个Socket

参数1：设置协议的类型    参数2：套接字的双向数据流   参数3：使用tcp通信协议

5.停止监听按钮

 private void btncancel_Click(object sender, EventArgs e){btncancel.Enabled = false;if (socket != null){socket.Shutdown(SocketShutdown.Both);socket.Close();}ServerSocket.Close();t1.Abort();btnstart.Enabled = true;}

6.发送信息效果展示

 private void btnsend_Click(object sender, EventArgs e){string s=textBox3.Text;byte[]buffer=Encoding.UTF8.GetBytes(s);try{int r = socket.Send(buffer);Showmasg("发送成功");textBox3.Clear();}catch (Exception ex){throw;}}
