空消息，同时从插座

接收数据我试图连接到服务器UAP（用于华为发送和接收USSD消息）使用Socket类，但同时从服务器接收数据有问题。我可以正确连接到服务器，也可以将数据发送到服务器，但我在接收数据时遇到问题。空消息，同时从插座

这是我的连接和发送消息代码：

IPAddress ipAddress = IPAddress.Parse("127.0.0.1"); //server 
IPEndPoint remoteEP = new IPEndPoint(ipAddress, 2020); 

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

clientSocket.Connect(remoteEP); 

//bind to socket, here I send bind message 
Bind();

和Bind功能里面，我叫receive方法从服务器获取数据：

private static void receive() 
{ 
    try 
    { 
     // Create the state object. 
     StateObject state = new StateObject(); 
     state.workSocket = clientSocket; 

     // Begin receiving the data from the remote device. 
     clientSocket.BeginReceive(state.buffer, 0, StateObject.BufferSize, 0, 
      new AsyncCallback(receiveCallback), state); 

    } 
    catch (Exception ex) 
    { 
     Console.WriteLine("receive | " + ex.ToString()); 
    } 

}//receive

在这里你可以看到我的Wireshark日志而连接，发送数据和从服务器接收数据：
