WCF异常——故障状态

我将WCF服务引用添加到我的项目中。下一步是从代码中创建一个通道。

 WSHttpBinding bindingDialingType = new WSHttpBinding();
        EndpointAddress endingPointDialingType = new EndpointAddress("http://wsvc.corporate.my.com/International/DialingService.svc");
        ChannelFactory<IDialingService> iDialingServiceChannelFactory = new ChannelFactory<IDialingService>(bindingDialingType, endingPointDialingType);
        IDialingService instanceIDialingService = iDialingServiceChannelFactory.CreateChannel();

因为我遇到了一个异常，所以我猜我的通道工厂代码有问题。

The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the Faulted state.

为了捕获异常，我编写了以下代码:

My app.config is:
 <system.serviceModel>
  <bindings>
   <basicHttpBinding>
    <binding name="BasicHttpBinding_iLuCRE" />
   </basicHttpBinding>
   <wsHttpBinding>
    <binding name="WSHttpBinding_IDialingService">
     <security mode="None" />
   </binding>
   </wsHttpBinding>
  </bindings>
  <client>
   <endpoint address="http://wsvc.corporate.my.com/LuCRE/LuCRE.svc"
    binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_iLuCRE"
    contract="LuCRE.iLuCRE" name="BasicHttpBinding_iLuCRE" />
   <endpoint address="http://wsvc.corporate.my.com/International/DialingService.svc"
    binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IDialingService"
    contract="DialingService.IDialingService" name="WSHttpBinding_IDialingService" />
  </client>
 </system.serviceModel>

我使用WCFTestClient来测试它，但是该服务确实工作。我将服务引用添加到我的项目中，但我不知道代码细节。

更新:

如果我使用代码

 DialingServiceClient client = new DialingServiceClient();

然后通过client调用该方法，则一切正常。为什么?

WSHttpBinding bindingDialingType = new WSHttpBinding
   { Security = new WSHttpSecurity { Mode = SecurityMode.None } };
