问题描述

我正在运行 IIS 7 集成模式，并且正在运行

I'm running IIS 7 Integrated mode and I'm getting

请求在此上下文中不可用

当我尝试在从 Application_Start 调用的 Log4Net 相关函数中访问它时.这是我的代码行

when I try to access it in a Log4Net related function that is called from Application_Start. This is the line of code I've

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

并且正在抛出异常以进行第二次比较.

and an exception is being thrown for second comparison.

除了检查 HttpContext.Current.Request 是否为 null 之外，我还能检查什么??

What else can I check other than checking HttpContext.Current.Request for null??
