Debug模式下因为
函数调用层次过多导致StackOverFlowException
后来在一些位置使用了Task.Factory.StartNew

IVDataQueueProvider.GetAsync

  public void GetAsync(Variety arg_vOption, Action<ErrorObject, IVDataQueue> arg_fnRet)
        {
            if(_dtQueue.ContainsKey(arg_vOption))

                        //所以这里采用Task来跳出Stack
