Unless I got you wrong, checking the version displayed for System.Web.Mvc in your windows\assembly folder should help you.
除非我弄错了，否则检查 windows\assembly 文件夹中为 System.Web.Mvc 显示的版本应该对您有所帮助。

C:\Program Files (x86)\Microsoft ASP.NET Inside this folder will be all versions of MVC that you have installed. This is for Win 7.
C:\Program Files (x86)\Microsoft ASP.NET 此文件夹内将包含您已安装的所有 MVC 版本。这适用于 Win 7。

Simply looking in the Program Files(x86) isn't enough. If you've installed MVC5 for instance via NuGet, then you won't see a MVC5 folder under that folder. In my opinion, the most effective way of knowing which version of MVC you are using is to go to your VS project and look at the references under your main web application. Then find "System.Web.Mvc", right click, then click properties. You will see the version as a property. I tried to post an image of this but it won't allow me to do that; oh well, sorry I couldn't.
仅仅查看 Program Files(x86) 是不够的。例如，如果您已经通过 NuGet 安装了 MVC5，那么您将不会在该文件夹下看到 MVC5 文件夹。在我看来，了解您使用的是哪个版本的 MVC 的最有效方法是转到您的 VS 项目并查看您的主 Web 应用程序下的引用。然后找到“System.Web.Mvc”，右键单击，然后单击属性。您将看到版本作为属性。我试图张贴这张图片，但它不允许我这样做；哦，对不起，我不能。

"don't forget to set properties of mvc.dll to 'copy local true' if you are using older version of MVC than latest installed or it will not work.
“如果您使用的 MVC 版本比最新安装的旧版本，请不要忘记将 mvc.dll 的属性设置为 'copy local true'，否则它将无法工作。

The ASP.NET programs folder is the best place to look as it will show the versions in folders. To note though, if you installed Visual Studio 2012, then it installed both versions MVC3 and MVC4.
ASP.NET 程序文件夹是最佳查看位置，因为它将显示文件夹中的版本。但请注意，如果您安装了 Visual Studio 2012，则它同时安装了 MVC3 和 MVC4 版本。
