Question

任何人都可以提供一些意见来确定问题。

这是我的流程：

我有一个应用程序执行冗长的图像处理，从单页tiff文件生成多个多页tiff文件，文件分离是扫描单页tiff文件上的条形码。
多页tiff文件的名称与条形码相同。这些最初存储在临时工作文件夹中。
我浏览了临时工作文件夹路径中的每个多页tiff文件，提取条形码（文件名）并调用wcf服务以获取网络路径。
我将多页tiff文件移动到各自的网络路径。

我的问题是对GetNetworkPath(imageID)的调用随机失败。这是服务跟踪。非常感谢任何帮助。

我尝试检查服务状态并打开服务，如果它出现故障但没有帮助。

LookupManagerServiceClient client = new LookupManagerServiceClient();
    if (client.State.Equals(System.ServiceModel.CommunicationState.Faulted) ||
        client.State.Equals(System.ServiceModel.CommunicationState.Closing) ||
        client.State.Equals(System.ServiceModel.CommunicationState.Closed))
    {
             client = new LookupManagerServiceRef.LookupManagerServiceClient();
            }
_result = client.GetNetworkPath(_imageID);

WCF调用随机失败
