asp.net监听端口问题

Question

private void StartListen()
        {
            int port = 5000;
            TcpListener myTcpListener = new TcpListener(port);
            myTcpListener.Start();
            ReceiveSocket = myTcpListener.AcceptSocket();//监听已建立
            this.Receive();
        }        private void Receive()
        {
            try
            {
                while (true)
                {
                    if (ReceiveSocket.Connected)
                    {
                        NetworkStream = new NetworkStream(ReceiveSocket);
                        byte[] data = new byte[512];
                        byte[] buf = new byte[1];
                        buf[0] = 124;
                        NetworkStream.Read(data, 0, data.Length);
                        Msg = Encoding.UTF8.GetString(data);                        string Friends = Fs.getUserFriend(Convert.ToInt32(Msg));
                        string[] FriendArray = Friends.Split('|');
                        Friend.Model fm;
                        foreach (string D in FriendArray)
                        {
                            fm = new Friend.Model();
                            fm.UID = Convert.ToInt32(D);
                            fm.UserName = Us.getUserName(Convert.ToInt32(D));
                            data=Serialize.Serializer.ObjectToByte(fm);
                            NetworkStream.Write(data, 0, data.Length);
                        }
                        NetworkStream.Write(buf, 0, buf.Length);
                    }
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }上面的代码放在StartListen.aspx.cs文件中，通过浏览器访问这个页面实现监听。但为什么会出现这种情况

Answer 1

把代码改成了private void StartListen()
        {
            int port = 5000;
            TcpListener myTcpListener = new TcpListener(port);
            myTcpListener.Start();
            ReceiveSocket = myTcpListener.AcceptSocket();//监听已建立
            this.Receive();
        }        private void Receive()
        {
            try
            {
                while (true)
                {
                    if (ReceiveSocket.Connected)
                    {
                        NetworkStream = new NetworkStream(ReceiveSocket);
                        byte[] data = new byte[512];
                        byte[] buf = new byte[1];
                        buf[0] = 124;
                        NetworkStream.Read(data, 0, data.Length);
                        Msg = Encoding.UTF8.GetString(data);                        string Friends = Fs.getUserFriend(Convert.ToInt32(Msg));
                        string[] FriendArray = Friends.Split('|');
                        Friend.Model fm;
                        foreach (string D in FriendArray)
                        {
                            fm = new Friend.Model();
                            fm.UID = Convert.ToInt32(D);
                            fm.UserName = Us.getUserName(Convert.ToInt32(D));
                            data=Serialize.Serializer.ObjectToByte(fm);
                            NetworkStream.Write(data, 0, data.Length);
                        }
                        NetworkStream.Write(buf, 0, buf.Length);
                        ReceiveSocket.Close();
                    }
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }红色部分是修改的部分，但仍然这样我的本意是在服务器端用一个socket监听所有客户端连接，一个客户端连接之后发送数据，发送完成之后继续接收下一个客户端的连接，而不是新开一个监听端口这到底要怎么弄才行？

public void CreatSocket()
    {
        try
        {
            int port = 2000;
            string host = "127.0.0.1";
            /**/
            ///创建终结点（EndPoint）  
            IPAddress ip = IPAddress.Parse(host);//把ip地址字符串转换为IPAddress类型的实例  
            IPEndPoint ipe = new IPEndPoint(ip, port);//用指定的端口和ip初始化IPEndPoint类的新实例                  /**/            ///创建socket并开始监听 
            Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);//创建一个socket对像，如果用udp协议，则要用SocketType.Dgram类型的套接字              s.Bind(ipe);//绑定EndPoint对像（2000端口和ip地址） 
            s.Listen(0);//开始监听  
            Console.WriteLine("等待客户端连接");
            /**/            ///接受到client连接，为此连接建立新的socket，并接受信息  
            while (true)//定义循环，以便可以简历N次连接  
            {
                Socket temp = s.Accept();//为新建连接创建新的socket  
                //Console.WriteLine("建立连接");  
                string recvStr = "";
                byte[] recvBytes = new byte[1024];
                int bytes;
                bytes = temp.Receive(recvBytes, recvBytes.Length, 0);//从客户端接受信息  
                recvStr += Encoding.ASCII.GetString(recvBytes, 0, bytes);
                DBHelper.ExecutCommand("INSERT INTO [ShuJu]([strs_VAR]) VALUES('" + recvStr + "')");//存入数据库  
                if (temp != null)                    temp.Close();
            }            /**/
            ///给client端返回信息  
            //Console.WriteLine("server get message:{0}", recvStr);//把客户端传来的信息显示出来  
            //string sendStr = "ok!Client send message successful!";  
            //byte[] bs = Encoding.ASCII.GetBytes(sendStr);  
            //temp.Send(bs, bs.Length, 0);//返回信息给客户端  
            //temp.Close();  
            s.Close();
            //Console.ReadLine();  
        }
        catch (Exception ex)
        {
            string s = ex.ToString();
        }    }调用
void Application_Start(object sender, EventArgs e)   
     {           
       // 在应用程序启动时运行的代码  
         (new System.Threading.Thread(new System.Threading.ThreadStart( new Class1().CreatSocket))).Start();//开辟一个新线程  
      }
