我有一个3层架构并使用tcp套接字在传输层(TCP客户端)中发送一些数据这种方法是使用BeginSend方法异步的.

public void TransportData(Stream stream)
{
    try
    {
        SetTransporterState(StateObject.State.SendingData);
        if (clientSock.Connected)
        {
            ASCIIEncoding asen = new ASCIIEncoding();
            stream.Position = 0;
            byte[] ba = GetStreamAsByteArray(stream);
           if (clientSock.Connected)
              clientSock.BeginSend(ba, 0, ba.Length, SocketFlags.None, new AyncCallback(SendData), clientSock);
           else
               throw new SockCommunicationException("Socket communication failed");

         }
         catch (SocketException sex)
         {
             throw sex;
         }
         catch (SockCommunicationException comex)
         {
             bool rethrow = ExceptionPolicy.HandleException(comex, "TransportLayerPolicy");
         if (rethrow)
         {
             throw;
         }
       }
     }
   }
   catch (SocketException soex)
   {
     throw soex;
   }
   catch (SockCommunicationException comex)
   {
      bool rethrow = ExceptionPolicy.HandleException(comex, "TransportLayerPolicy"); …
