推荐答案

ViewBag是动态集合.在您的控制器中，您可以将所需的任何内容放入其中，然后从视图中调用它.它们可以是您想要的任何对象和任何类型.

ViewBag is a dynamic collection. In your controller you can put whatever you want in it and call it from your View. They can be whatever objects and whatever types you want.

您提供的指向

The link you provided to the MSDN Documentation is providing an example of this.

如果您的控制器中包含以下内容:

If you have the following in your controller:

ViewBag.Something = thing;

事物在某处声明，您正在这里访问它.您无需声明 ViewBag ，并且在为其分配 thing 时， Something 会自动声明.

thing is declared somewhere, and you are accessing it here. You don't declare ViewBag, and Something gets automatically declared when you assign thing to it.
