在Application_Start事件Request对象 [英] Request object in Application_Start event

问题描述

我们目前使用这行代码来获得在Application_Start事件中的当前应用程序的URL。

We currently use this line of code to get the current applications url in the Application_Start event.

string sApplicationURL = HttpContext.Current.Request.Url.Scheme + "://" 
                         + HttpContext.Current.Request.Url.Authority 
                         + HttpContext.Current.Request.ApplicationPath;

我刚刚发现，在IIS7.0请求对象不再可用时，Application_Start事件被激发。

I just recently found out that in IIS7.0 the Request object is no longer available when the Application_Start event is fired.

有另一种方式来获得当前应用程序的URL，而无需使用Request对象？

Is there another way to get the current applications url without using the Request object?

感谢

推荐答案

有一个看看这个：

在综上所述，由于请求上下文不再提供给Application_Start事件发生错误。该博客指出两个选择来处理此错误：

In summary, the error occurs because the Request context is not longer available to the Application_Start event. This blog states two choices to deal with this error:

1）改变你的代码工作W / O请求，或者
2）修改您的应用程序运行在经典模式（不推荐）。

1) Change your code to work w/o Request, or 2) Modify your application to run in Classic Mode (not recommended).

要获得ApplicationPath，使用 HttpRuntime.AppDomainAppVirtualPath

To get the ApplicationPath, use HttpRuntime.AppDomainAppVirtualPath.
