如何克服 System.ServiceModel.FaultException

更新我的 WCF 客户端的服务引用时(只需在 Visual Studio 2008 中单击更新服务引用),发生以下错误:System.ServiceModel.FaultException:消息...
我创建了 ErrorServiceBehavior 类。由于此类行为是为错误处理而创建的,因此必须将 IErrorHandler 实现应用于每个通道调度程序。
public class ErrorServiceBehaviour : Attribute, IServiceBehavior
{
...
public Type FaultType
{
get { return _faultType; }
set { _faultType = value; }
}
public void ApplyDispatchBehavior(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase)
{
foreach (ChannelDispatcher dispatcher in serviceHostBase.ChannelDispatchers)
{
dispatcher.ErrorHandlers.Add(new ErrorHandler(_faultType));
}
}
}
public class ErrorHandler : IErrorHandler
{
public ErrorHandler(Type faultType)
{
_faultType = faultType;
}
...
}
后来,我通过将 ErrorServiceBehavior 属性应用于我的服务类来使用该行为:
[ErrorServiceBehavior(FaultType = typeof(MyServiceFault))]
public class MyService : IMyService
{
...
}
问题是,当我注释掉 ApplyDispatchBehavior 方法中的 foreach 循环时,我根本没有收到任何错误,但这不是出路(因为我希望我的错误得到处理)。
下面是我的服务配置:
<system.serviceModel>
<services>
<service behaviorConfiguration="DefaultBehavior" name="MyService">
<endpoint address="" binding="wsHttpBinding" contract="IMyService" bindingConfiguration="NoSecurityBinding"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="DefaultBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<wsHttpBinding>
<binding name="NoSecurityBinding" >
<security mode="None">
<transport clientCredentialType="None"/>
<message establishSecurityContext="false"/>
</security>
</binding>
<binding name="DefaultBinding" />
</wsHttpBinding>
</bindings>
</system.serviceModel>
替换代码并尝试:
<bindings>
<wsHttpBinding>
<binding name="NoSecurityBinding" >
<security mode="None">
<transport clientCredentialType="None"/>
<message clientCredentialType="None"/>
</security>
</binding>
<binding name="DefaultBinding" />
</wsHttpBinding>
</bindings>
