如何在连接时读取套接字的响应？

Question

在我的项目中，我正在维护一个异步Socket连接，以便向手机发送消息。所以，我的问题是这个连接是异步的，所以当很长时间没有数据到达时，远程服务器套接字会自动关闭连接。因此，即使没有数据传输，我的要求是使连接始终保持24小时。我的客户也希望一直看到接收和发送状态。这样他们就能理解正在发生的事情。但我在这方面很新，所以我需要帮助来实现这一需求。任何帮助将不胜感激。

我的问题是：

1. 当套接字连接到服务器套接字时，它是否可能收到一些字节？即使根本没有数据传输？

2. 如果连接客户端套接字后收到一些数据，我该如何实现？

下面是我的BeginReceive（）和Callback方法的代码：

  #region Receive & ReceiveCallBack
    public void Receive(Socket client)
    {
        if (m_clientSocket.Connected)
        {
            StateObject state = new StateObject();
            state.workSocket = client;

            client.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0, new AsyncCallback(ReceiveCallback), state);
        }

        else
        {
            Connect();
        }
    }

    public void ReceiveCallback(IAsyncResult ar)
    {
        if (m_clientSocket.Connected)
        {
            StateObject state = (StateObject)ar.AsyncState;
            Socket client = state.workSocket;
            string receiveData = "";
            string sendData = "";

            int bytesRead = client.EndReceive(ar);

            if (bytesRead > 0)
            {

                state.sb.Append(System.Text.Encoding.ASCII.GetString(state.buffer, 0, bytesRead));

                client.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0, new AsyncCallback(ReceiveCallback), state);

                receiveData = state.sb.ToString();
                this.Invoke((MethodInvoker)(() => IsBulk.Items.Add(receiveData)));

                sendData = getReply(receiveData);
                write_log(DateTime.Now.ToString() + " : " + receiveData, "bytesRead", "bytesRead");

                try
                {
                    Object objData = sendData;
                    byte[] byData = System.Text.Encoding.ASCII.GetBytes(objData.ToString());
                    if (m_clientSocket != null)
                    {
                        m_clientSocket.Send(byData);
                    }

                    write_log(DateTime.Now.ToString() + " : " + sendData, "sendData", "sendData");
                }
                catch (SocketException se)
                {
                    logstr = se.Message;
                    write_log(logstr, "WaitForData", "waitfordata");
                }

            }
            else
            {

                receiveData = state.sb.ToString();
                if (!string.IsNullOrEmpty(receiveData))
                {
                    write_log(DateTime.Now.ToString() + " : " + receiveData, "receiveData2", "receiveData2");
                }


                receiveDone.Set();
            }
            state.sb.Clear();
        }
        else
        {
            Connect();
        }
    }
    #endregion

    private void Connect()
    {

        m_clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);


        IPAddress ip = IPAddress.Parse("10.151.41.134");

        int iPortNo = System.Convert.ToInt16("6561");

        IPEndPoint ipEnd = new IPEndPoint(ip, iPortNo);

        m_clientSocket.Connect(ipEnd);

        if (m_clientSocket.Connected)
        {
            this.stStatus.Text = "Server Connected";

            timer3.Enabled = true;
            timer4.Enabled = true;
        }
        else
        {
            this.stStatus.Text = "Server Failed to Connect";
            m_clientSocket.Shutdown(SocketShutdown.Both);
        }

    }

更新：这是我必须在Windows程序中显示的内容：



谢谢。
