通信:Winform(结合C#)TCP服务端

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2M byte[]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; } } 六、清目了然的CV吧 using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Net; using System.Net.Sockets; using System.Text; using System.Threading; using System.Threading.Tasks; using System.Windows.Forms; namespace TCP服务器 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } //创建Socket public Socket ServerSocket { get; set; } public Socket SocketAccept { get; set; } public Socket socket; private void Showmasg(string s) { listBox1.BeginInvoke(new Action<string>(str => { listBox1.Items.Add(str); }), s); } Thread t1; Thread t2; private void btnstart_Click(object sender, EventArgs e) { btnstart.Enabled=false; btncancel.Enabled=true; ServerSocket=new Socket(AddressFamily.InterNetwork,SocketType.Stream, ProtocolType.Tcp); IPAddress iPAddress=IPAddress.Parse(textBox1.Text); int port=int.Parse(textBox2.Text); IPEndPoint iPEndPoint=new IPEndPoint(iPAddress, port); try { ServerSocket.Bind(iPEndPoint); 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) { 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; byte[]buffer=new byte[1024*1024*2]; int r=socket.Receive(buffer); if (r==0) { return; } string s=Encoding.UTF8.GetString(buffer); Showmasg(s); } 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; } 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; } } private void Form1_Load(object sender, EventArgs e) { System.Diagnostics.Process.Start(@"D:\17_SocketTool\SocketTool.exe"); } } }
