我有我的/ Views文件夹中的默认_ViewStart.cshtml。我想能够访问我的ViewBag对象，所以我可以设置所有我的视图的默认标题。
但是，用：
@{
Layout = "~/Views/Shared/SiteLayout.cshtml";
ViewBag.Title = "bytecourse - Online Courses in Technology";
}
我得到“名称’ViewBag’在当前上下文中不存在”作为运行时错误。
我需要做什么？
解决方法
简而言之…使用控制器的查看包。
ViewContext.Controller.ViewBag.MyVar = "myVal";
和
@ViewContext.Controller.ViewBag.MyVar

Generally,ViewData[“StoreName”] is same as ViewBag.StoreName
Also,Controller.ViewData[“StoreName”] = Controller.StoreName =
ViewContext.Controller.ViewBag.StoreName
=ViewContext.Controller.ViewData[“StoreName”]But every view and partial view gets its own instance of viewdata.
