能够访问会话状态的Global.asax事件

问题描述

我试图访​​问会话状态在我的Global.asax为每个请求（网页，文档，PDF等）。我知道我不能这样做在的Application_BeginRequest，我以为我的Application_AcquireRequestState，但它不会工作，这很奇怪，因为它在另一个项目。

I'm trying to access the session state in my global.asax for every request (page, documents, PDF, etc.). I know i can't do that in Application_BeginRequest, and i thought i could in Application_AcquireRequestState, but it won't works, which is strange because it works in another project.

所以，我在找一个事件中，我总是有机会获得会话状态为每一个请求。

So, i'm looking for an event in which i would always have access to the session state for every request.

感谢

我试着这样做

Sub Application_PreRequestHandlerExecute(ByVal sender As Object, ByVal e As EventArgs)
    Session("test") = "test"
End Sub

但我仍然得到错误，因为我没有访问会话状态。

But i still get errors as i don't have access to session state.

推荐答案

会话被Application_AcquireRequestState期间加载。您安全的赌注是建立 Application_ preRequestHandlerExecute 和访问它。

The session gets loaded during Application_AcquireRequestState. Your safe bet is to build Application_PreRequestHandlerExecute and access it there.

更新：并不是每一个请求有一个会话状态。您还需要检查空：如果（！System.Web.HttpContext.Current.Session = NULL）

Update: Not every request has a session state. You need to also check for null: if (System.Web.HttpContext.Current.Session != null).
