if (HttpContext.Current != null && HttpContext.Current.Request != null)

和一个异常被抛出了第二个比较。

推荐答案

请参阅<一个href=\"http://mvolo.com/iis7-integrated-mode-request-is-not-available-in-this-context-exception-in-applicationstart/\">IIS7集成模式：请求不可用在的Application_Start 这种情况下例外：

Please see IIS7 Integrated mode: Request is not available in this context exception in Application_Start:

请求不在此可用
  背景的例外就是就越会

The "Request is not available in this context" exception is one of the more common errors you may receive on when moving ASP.NET applications to Integrated mode on IIS 7.0. This exception happens in your implementation of the Application_Start method in the global.asax file if you attempt to access the HttpContext of the request that started the application.
