asp.net-mvc - 类型或命名空间 ActionExecutingContext 或 ActionFilterAttribute

Question

你好，突然我的 mvc 应用程序开始出现异常:

rror    36  The type or namespace name 'ActionExecutingContext' could not be found (are you missing a using directive or an assembly reference?)    C:\Users\TMM\Desktop\04.09\BEAWEB_WITH_LANG - Copy\MvcBeaWeb\MvcBeaWeb\Filters\InitializeSimpleMembershipAttribute.cs   18  48  MvcBeaWeb
Error   22  The type or namespace name 'ActionFilterAttribute' could not be found (are you missing a using directive or an assembly reference?) C:\Users\TMM\Desktop\04.09\BEAWEB_WITH_LANG - Copy\MvcBeaWeb\MvcBeaWeb\Filters\NoCacheAttribute.cs  9   36  MvcBeaWeb
Error   30  The type or namespace name 'ActionFilterAttribute' could not be found (are you missing a using directive or an assembly reference?) C:\Users\TMM\Desktop\04.09\BEAWEB_WITH_LANG - Copy\MvcBeaWeb\MvcBeaWeb\Filters\InitializeSimpleMembershipAttribute.cs   12  63  MvcBeaWeb
Error   39  The type or namespace name 'ActionResult' could not be found (are you missing a using directive or an assembly reference?)  C:\Users\TMM\Desktop\04.09\BEAWEB_WITH_LANG - Copy\MvcBeaWeb\MvcBeaWeb\Controllers\AccountsController.cs    24  16  MvcBeaWeb

我什至重新安装了 Visual Studio 2012!

最诚挚的问候，

米卡的回答对我有用。 Windows 更新到底是什么？ “您可以做的就是在 mvc Web 应用程序的引用文件夹中 - 删除对 System.Web.Mvc 的引用，然后再次添加对 System.Web.Mvc 的引用。这解决了我的问题!是的，问题是因为更新”
