Easy DataServiceContext有问题吗? [英] Easy DataServiceContext Question?

问题描述

大家好，

我认为这很容易-我在C#客户端应用程序中使用DataServiceContext-如果发生异常(例如，在调用SaveChanges时)，我可以调用客户端获取异常详细信息的任何功能吗? br/>
使用WP7客户端时，我注意到调试器似乎显示了更多信息-例如失败，因为属性X不能为空"，

有什么想法吗?

在此先感谢！

Hi All,

I think this is an easy one - I am using a DataServiceContext in a C# client application - if there is an exception, for example when calling SaveChanges, is there any function I can call client-side to get the details of the exception?

when using a WP7 client I noticed the debugger seems to show more info - for example ''Failed because Property X cannot be null'',

Any ideas?

Thanks in advance!

推荐答案

大家好，

如果有人遇到相同的问题，请使用以下属性装饰服务类:

Hi All,

In case anyone has the same problem, decorate the service class with the following attribute:

[System.ServiceModel.ServiceBehavior(IncludeExceptionDetailInFaults = true)]

有关更多信息，您还可以将以下内容添加到web.config文件中:

For further info you can also add the following to the web.config file:

<system.diagnostics>
  <sources>
    <source name="System.ServiceModel"

            switchValue="Information, ActivityTracing"





            propagateActivity="true">
      <listeners>
        <add name="traceListener"

            type="System.Diagnostics.XmlWriterTraceListener"

            initializeData= "c:\log\Traces.svclog" />
      </listeners>
    </source>
  </sources>
</system.diagnostics>
