The name 'ViewBag' does not exist in the current context -- When in an "Area"
提问by 010110110101
My problem is very similar to this problem, except mine is in a sub-Area (right click, Create Area)
我的问题与这个问题非常相似，除了我的在一个子区域中（右键单击，创建区域）
The name 'ViewBag' does not exist in the current context
I ran the upgrade tool and it did discover the web.config in the area, but I still get the error. My layout page is very simple:
我运行了升级工具，它确实发现了该区域中的 web.config，但我仍然收到错误消息。我的布局页面非常简单：
<!DOCTYPE html>
<html>
<head>
<title>@ViewBag.Title</title>
</head>
<body>
<div>
@RenderBody()
</div>
</body>
</html>
And my content page looks like this near the top:
我的内容页面在顶部附近看起来像这样：
@model IEnumerable<ProjectName.Models.OrderViewModel>
@{
ViewBag.Title = "Index";
Layout = "~/Areas/Admin/_AdminLayoutPage.cshtml";
}
<h2>Index</h2>

You should be aware that when creating an MVC application, you get two Web.Configfiles. One in the root of the project and one under the Views folder. I had the same issue and for some reason when I was working on my project, I accidentally modified the one under the Views. Cleaning it (the one under the Views folder) fixed that error. Hope it helps.
您应该知道，在创建 MVC 应用程序时，您会得到两个Web.Config文件。一个在项目的根目录下，一个在 Views 文件夹下。我遇到了同样的问题，出于某种原因，当我在做我的项目时，我不小心修改了视图下的那个。清理它（Views 文件夹下的那个）修复了这个错误。希望能帮助到你。

I have web.config working in an area. See if your web.config in your View folder of the area has s part like following
我有 web.config 在一个区域工作。查看该区域的 View 文件夹中的 web.config 是否有如下部分

Check to make sure that the web.config file located in your "Views" directory is located at the ROOT of that directory. I accidentally moved it to "Shared" directory and tore my hair out for a while until I figured this out...
检查以确保位于“视图”目录中的 web.config 文件位于该目录的根目录下。我不小心把它移到了“共享”目录，然后把我的头发扯了一段时间，直到我弄明白了……
