是HttpContext.Current在Web应用程序自从空？ [英] Is HttpContext.Current Ever Null in a Web Application?

问题描述

时HttpContext.Current在Web应用程序不断为空（未使用假设线程）？更具体地说，它会永远是空的无效Application_OnError（对象发件人，EventArgs五）？

Is HttpContext.Current ever null in a web Application (assuming threads are not being used)? More specifically, would it ever be null in void Application_OnError(object sender, EventArgs e)?

推荐答案

看<一个href=\"http://stackoverflow.com/questions/668447/asp-net-c-applicationerror-in-global-asax-cannot-access-session-variables\">this另一个问题

会议未初始化，直到AcquireRequestState事件添加，所以这点之前发生的任何错误将不会有会话变量。

Session is not initialized until the AcquireRequestState event, so any error occurring before this point will not have session variables available.

我认为同样适用于HttpContext.Current为HttpContext.Current.Session

I think the same applies to HttpContext.Current as HttpContext.Current.Session

所以，是的，我认为HttpContext.Current有时是空的Application_OnError

So yes, I think HttpContext.Current can sometimes be null in Application_OnError
