答

是否this申请？服务器显然是IIS7，你的本地主机可能是IIS6。

从链接引用提到：

这个错误是由于在IIS7集成管道，使得在Application_Start事件无法请求上下文中的设计更改。当使用经典模式（在以前的版本的IIS上运行时的唯一模式）时，尽管Application_Start事件始终打算作为应用程序中的全局和请求不可知事件，但该请求上下文曾经可用，即使也可用一生。尽管如此，由于ASP.NET应用程序总是通过对应用程序的第一次请求启动，因此通过静态HttpContext.Current字段可以获得请求上下文。

不知道这是否有助于某人.. 但我将应用程序池设置为经典.NET AppPool，并且错误消失。

答

请在代码中使用的

HttpContext.Current.Response.Redirect("PageName");

代替

Response.Redirect("PageName");

。
