C#实现Socket传输简单数据

<script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </script>

运行程序后， 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.Windows.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 = true;
            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(object sender, DoWorkEventArgs e)
        ...{
            Socket receiveSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            IPEndPoint endpoint = new IPEndPoint(0, 8000);

            receiveSocket.Bind(endpoint);
            receiveSocket.Listen(10);

           
            try
            ...{
