名称"ViewBag"在当前上下文中不存在 [英] The name 'ViewBag' does not exist in the current context

问题描述

我正在尝试在我的应用程序中使用ViewBag，我拥有所有最新的dll，MVC 3的最新版本，但仍然出现错误:

I am trying to use ViewBag in my application, I have all of the recent dlls, the latest version of MVC 3, but yet I am still getting the Error:

名称'ViewBag'在当前上下文中不存在"

"The name 'ViewBag' does not exist in the current context"

我什至卸载并重新安装了MVC 3，但没有任何变化.

I have even uninstalled and then re-installed MVC 3 and yet there is no change.

此外，我不认为该dll在GAC中显示.

Also, I do not believe that the dll's are showing up in the GAC.

我可能是什么问题?或如何将dll添加到GAC?

What might be my problem? Or how to add the dll's to the GAC?

推荐答案

您需要将MVC特定的Razor配置添加到web.config.参见此处:找不到Razor HtmlHelper扩展(或其他用于视图的命名空间)

You need to add the MVC-specific Razor configuration to your web.config. See here: Razor HtmlHelper Extensions (or other namespaces for views) Not Found

使用 MVC 3升级工具，以自动确保您拥有正确的配置值.

Use the MVC 3 upgrade tool to automatically ensure you have the right config values.
