C＃WCF客户端错误

Question

我试图调用WCF web服务函数来发送数据和我收到波纹管例外

System.ServiceModel.FaultException: The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the <serviceDebug> configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework SDK documentation and inspect the server trace logs.

我在相同的应用程序和同样的形式称为同一Web服务的其他功能，它工作正常。但这不是。

任何人都可以请向我解释什么意思这个例外，如何解决它？ 谢谢

在web服务端有一些例外。 可以调试webservice方法，也可以在webservice配置文件中设置IncludeExceptionDetailInFaults = true。
