推荐答案

来自 ASP.NET网站:

ViewBag是一个动态对象，这意味着您可以放置​​任何想要的东西 进去;在您放置ViewBag对象之前，它没有定义的属性 里面的东西.

ViewBag is a dynamic object, which means you can put whatever you want in to it; the ViewBag object has no defined properties until you put something inside it.

ViewBag.Title属性只是一个字符串对象.在这种情况下，实际上是在视图中使用它定义 Title属性.如果您要查看_Layout.cshtml文件，则可能会看到类似以下内容的

The ViewBag.Title property is simply a string object. In this case it's being used in the view to actually define the Title property. If you were to look in your _Layout.cshtml file you would likely see something like:

<title>@ViewBag.Title</title>

还记得在视图中定义属性的时间吗?最终呈现页面后，该属性最终出现在HTML标记中，如下所示:

Remember when the property was defined in the view? When the page is finally rendered, that property ends up in the HTML markup looking like:

<title>Store</title>

设置浏览器标题.
