C#实现Socket传输简单数据
[[wiki]wiki[/wiki]][/wiki]运行[wiki]程序[/wiki]后， 先要点击开始接收按钮后才能点击发送数据
Form1.cs代码如下
using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Text;using System.[wiki]windows[/wiki].Forms;using System.Net.Sockets;using System.IO;using System.Net;
namespace WinSocket...{ public partial class Form1 : Form ...{ BackgroundWorker bgWorker = null; public Form1() ...{ InitializeComponent(); bgWorker = new BackgroundWorker(); bgWorker.WorkerSupportsCancellation = tr[wiki]UE[/wiki]; this.AddEvent(); }
/**//// <summary> /// 注册事件 /// </summary> private void AddEvent() ...{ this.bgWorker.DoWork = new DoWorkEventHandler(bgWorker_DoWork); this.btnSend.Click = new EventHandler(btnSend_Click); this.btnStartReceive.Click = new EventHandler(btnStartReceive_Click); this.btnStopRecevie.Click = new EventHandler(btnStopRecevie_Click); }
void bgWorker_DoWork([wiki]object[/wiki] sender, DoWorkEventArgs e) ...{ Socket receiveSocket = new Socket(AddressFamily.InterNetwork, Socket[wiki]type[/wiki].Stream, ProtocolType.[wiki]TCP[/wiki]); IPEndPoint endpoint = new IPEndPoint(0, 8000);
receiveSocket.Bind(endpoint); receiveSocket.Listen(10);
try ...{ while (true) ...{ Socket tmpSocket = receiveSocket.Accept(); byte[] buffer = new byte[tmpSocket.ReceiveBufferSize]; if (tmpSocket.Receive(buffer) > 0) ...{ textBox2.Text = Encoding.UTF8.GetString(buffer) Environment.NewLine; } else ...{ System.Threading.Thread.Sleep(1000); }
} } catch(Exception err) ...{ MessageBox.Show(err.Message); } }
void btnStopRecevie_Click(object sender, EventArgs e) ...{ if (this.bgWorker.IsBusy) ...{ this.bgWorker.CancelAsync(); this.btnStartReceive.Enabled = true; this.btnStopRecevie.Enabled = false; } }
void btnStartReceive_Click(object sender, EventArgs e) ...{ this.btnStartReceive.Enabled = false; this.bgWorker.RunWorkerAsync(); this.btnStopRecevie.Enabled = true; }
void btnSend_Click(object sender, EventArgs e) ...{ Socket sendSocket = new Socket( AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); sendSocket.Connect("187.186.0.63", 8000);
byte[] buffer = Encoding.UTF8.GetBytes(textBox1.Text); sendSocket.Send(buffer); sendSocket.Shutdown(SocketShutdown.Both); sendSocket.Close(); }
private void Form1_Load(object sender, EventArgs e) ...{ this.btnStartReceive.Enabled = true; this.btnStopRecevie.Enabled = false; } }}Form.Designer.cs代码如下
namespace WinSocket...{ partial class Form1 ...{ /**//// <summary> /// 必需的设计器变量。 /// </summary> private System.ComponentModel.IContainer components = null;
/**//// <summary> /// 清理所有正在使用的资源。 /// </summary> /// <param name="dis[wiki]POS[/wiki]ing">如果应释放托管资源，为 true；否则为 false。</param> protected override void Dispose(bool disposing) ...{ if (disposing && (components != null)) ...{ components.Dispose(); } base.Dispose(disposing); }
