我想知道是否有去允许跟踪/诊断上通过app.config文件的SQLConnection很像你可以用，当你需要跟踪的支持（如下图）WCF？

Hi i was wondering if there is away to allow tracing / diagnostics on a SQLConnection via the app.config file much like you can with WCF when you need tracing support (as below)?

<system.diagnostics>
   <switches>
      <add name="DataMessagesSwitch" value="0" />
      <add name="TraceLevelSwitch" value="0" />
   </switches>
</system.diagnostics>

我试图拦截和记录从我的应用程序SQL请求（无需创建的IDbConnection垫片过的SQLConnection捕捉到的请求，因为他们执行）

I'm trying to intercept and log SQL requests from within my application (without needing to create an IDBConnection shim over a SQLConnection to capture the requests as they are executed)

有什么想法？
