我正在运行WCF服务和WPF应用程序。当我调用wpf应用程序上的数据时,就会显示此错误。

错误:

代码语言:javascript
运行

An unhandled exception of type 'System.ServiceModel.FaultException' occurred in mscorlib.dll

Additional information: 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.

我想问题是来自我的服务,但不太确定,有什么建议吗?

如错误消息所示,将includeExceptionDetailsInFaults更改为serviceDebug配置(web.config)中的true:

代码语言:javascript
运行
复制
<serviceDebug includeExceptionDetailInFaults="true"/>

因此,您将从服务中获得异常。
