c# - 在服务器上打开 IncludeExceptionDetailInFaults(来自 ServiceBehaviorAttribute 或 配置行为)

Question

我有一个运行良好的 WCF 服务，但我不知道发生了什么变化。

我得到这个异常:

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 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 3.0 SDK documentation and inspect the server trace logs.

这很令人困惑，因为我正在运行 .NET 4.0。

我在哪里打开 IncludeExceptionDetailInFaults？我正在努力寻找它。

定义一个 behavior在您的 .config 文件中:

<configuration>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="debug">
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    ...
  </system.serviceModel>
</configuration>

然后按照以下方式将行为应用于您的服务:

<configuration>
  <system.serviceModel>
    ...
    <services>
      <service name="MyServiceName" behaviorConfiguration="debug" />
    </services>
  </system.serviceModel>
</configuration>

您也可以通过编程方式设置它。参见 this question .
