C# WCF如何全局处理错误

C# WCF如何全局处理错误,c#,.net,wcf,C#,.net,Wcf,所以基本上我想集中处理WCF服务中的异常。为此,我创建了一个实现IErrorHandler的类和一个实现IServiceBehavior的类,在该服务行为实现中,我要说的是,对于每个通道调度器,我希望像这样添加自定义错误处理程序 public void ApplyDispatcherBehavior(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase) { IErrorHandler errorHa

所以基本上我想集中处理WCF服务中的异常。为此,我创建了一个实现
IErrorHandler
的类和一个实现
IServiceBehavior
的类,在该服务行为实现中,我要说的是,对于每个通道调度器,我希望像这样添加自定义错误处理程序

public void ApplyDispatcherBehavior(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase)
{
    IErrorHandler errorHandler = new CustomErrorHandler();
    foreach (var channelDispatcher in serviceHostBase.ChannelDispatchers)
    {
        channelDispatcher.ErrorHandlers.Add(errorHandler);
    }
}
我所做的最后一件事是创建了一个类,该类通过适当的实现从
BehaviorExtensionElement
派生,并在配置文件中注册了扩展名。但它似乎不起作用。我的意思是,我想做的事情是,如果异常未被处理,我想在一个集中的地方处理它。但它似乎对我不起作用。我的实现是否正确,我是否误解了我实现的整个事情应该如何工作。如有任何建议,将不胜感激

以下是您的web配置中缺少的配置文件部分

如果您尚未应用扩展,则需要在服务行为中添加扩展:

  <serviceBehaviors>
    <behavior name="defaultBehavior">
      <serviceDebug includeExceptionDetailInFaults="false" />
      <serviceMetadata httpGetEnabled="true" />

      <MyCustomBehaviorExtensionElement />
    </behavior>
  </serviceBehaviors>
配置文件:

<system.serviceModel>
  <extensions>
    <behaviorExtensions>
      <add name="webHttpWhithErrorHanlding" type="Server.Web.WebHttpWithErrorHandlingElement, Server.Web"/>
    </behaviorExtensions>
  </extensions>


  <!-- other staff -->
  <behaviors>
    <endpointBehaviors>
      <behavior name="webBehavior">
        <webHttpWhithErrorHanlding />
      </behavior>
    </endpointBehaviors>

  </behaviors>
</system.serviceModel>

然后将其应用于端点:

  <service name="YourServiceContract">

    <endpoint address=""
              binding="webHttpBinding"
              behaviorConfiguration="webBehavior"
