WinCE Socket.BeginSend()为什么数据发不出去呢?连接没有问题

Connect没有问题,断点调试连接没有问题,
关键是电脑服务端往手机端发数据,手机端能正确接收,
而手机端往电脑服务器端发数据,服务端打断点根本就走不到,也就是接收不到数据.
但手机端BeginSend()方法没有报错,这是怎么回事呢?

代码客户端发送



        public void ASend(byte[] SendData)

        {

            if (SendData == null)

            {

                return;

            }

            try

            {

                mSocket.BeginSend(SendData, 0, SendData.Length, 0, new AsyncCallback(SendCallBack), mSocket);

            }

            catch (Exception ex)

            {

                if (onClosed != null)//发送出现异常,则执行onClosed委托事件,

                {

                    onClosed(ID, "在线Socket发送数据出错" + ex.Message);

                }

            }

        }

服务端事件注册和接收数据代码



        private void TheListener_OnAccept(Maunite.Common.AsySocket AcceptedSocket)

        {

            AcceptedSocket.OnStringDataAccept += new Maunite.Common.StringDataAcceptHandler(Accept_OnStringDataAccept);//注册接收在线消息的事件

              AcceptedSocket.OnClosed += new Maunite.Common.AsySocketClosedEventHandler(Accept_OnClosed);//注册监听在线消息关闭的事件



              try

            {

                AcceptedSocket.BeginAcceptData();//这个原型代码在下面

              }

            catch (ArgumentNullException ex)

            {

                //            

            }

            //添加客户端

              theClient.Add(AcceptedSocket.ID, AcceptedSocket);

        }

        private void Accept_OnStringDataAccept(string AccepterID, string AcceptData)

        {

            MsgRef msgref = new MsgRef(ReceiveMessage);//MsgRef是申明的委托

              this.BeginInvoke(msgref, new object[] { AcceptData });

        }

        private void ReceiveMessage(string id, string msg)

        {

            try

            {

                string[] msgList = msg.Split('|');

                if (msg.Length < 1)

                {

                    return;

                }

                //code

            }

          }

//BeginAccept原型

         public void BeginAcceptData()

        {

            try

            {

                //开始接收数据

                  StateObject state = new StateObject();

                state.workSocket = mSocket;

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

            }

            catch (SocketException ex)//

            {

                if (onClosed != null)

                {

                    onClosed(ID, "在线Socket发送数据出错" + ex.Message);

                }

            }

        }
