用C#编写的 同步Socket通信接受数据不完整或接受不到，望知道的给与解答。
代码贴出来如下：
-------------------------------------                             Socket s = null;
                IPEndPoint hostEndPoint;
                IPAddress hostAddress = IPAddress.Parse(setting.FrontForIP);
                int conPort = int.Parse(setting.FrontForPort);
                hostEndPoint = new IPEndPoint(hostAddress, conPort);                // Creates the Socket to send data over a TCP connection.
                s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);                // Connect to the host using its IPEndPoint.
                s.Connect(hostEndPoint);                if (!s.Connected)
                {
                    s = null;
                }                byte[] msg = Encoding.UTF8.GetBytes(xmlBW);
                byte[] bytes = new byte[1024 * 10];
                string resp = string.Empty;
                try
                {
                    // Blocks until send returns.
                    int byteCount = s.Send(msg, 0, msg.Length, SocketFlags.None);
                   
                    // Get reply from the server.
                    byteCount = s.Receive(bytes, 0, bytes.Length, SocketFlags.None);                    int i = 0;
                    while (byteCount==0 && s.Available>0)
                    {
                        byteCount = s.Receive(bytes, 0, bytes.Length, SocketFlags.None);
                        if (i >= 4)
                            break;
                        i++;
                    }                    if (byteCount > 0)//表示有返回
                    {
                        resp = Encoding.UTF8.GetString(bytes);
                    }
                    s.Close();
                    return resp;                }
