如何获得在ASP.NET控制器中的'MvcApplication“实例？ [英] How to get an 'MvcApplication' instance in ASP.NET controller?

问题描述

我觉得 MvcApplication 是一个全球性的单。我想获得 MvcApplication 的实例在控制器中。然后，我把下面的code控制器中：

I think MvcApplication is a global singleton. I want to get the instance of MvcApplication in the controller. Then I put the following code in controller:

MvcApplication app = HttpContext.Current.Application as MvcApplication;

它给了我一个错误：

It gives me an error:

错误2'System.Web.HttpContextBase不包含当前和没有扩展方法当前接受型System.Web.HttpContextBase第一个参数的定义可以找到（是否缺少使用指令或程序集引用？）

Error 2 'System.Web.HttpContextBase' does not contain a definition for 'Current' and no extension method 'Current' accepting a first argument of type 'System.Web.HttpContextBase' could be found (are you missing a using directive or an assembly reference?)

为什么呢？如何访问 MvcApplication 控制器？
