我自己做了一些改变,似乎工作

它实际上现在工作.我删除了使用并在服务客户端添加了一些清理.

if (Service != null && Service.State != CommunicationState.Faulted)
                {
                    success = true;
                    Service.Close();
                }

            }
            catch (Exception ex)
            {
                msg = "Error" + Environment.NewLine + ex.Message + Environment.NewLine + ex.StackTrace;
            }
            finally{
                if (!success)
                {
                    if (Service != null) Service.Abort();
                }
            }

这是例外：

The communication object,System.ServiceModel.Channels.ServiceChannel,cannot be used for communication because it is in the Faulted state.
