问题描述

我需要做到以下几点：
我有一些现成控制器运行，但现在我想创建一个 BaseController 。
我的每控制器应该继承它是这样的：

I need to do the following: I have some Controllers ready and running, but now I want to create a BaseController. Each of my Controllers should inherit from it like this:

public class MySecondController : BaseController

这就是到目前为止已经运行。 现在的问题：

我要添加 ViewBag 进入这个基地控制器。这 ViewBag 应该从每一个被称为我的看法控制器accessable。

I want to add a ViewBag into this base controller. This ViewBag should be accessable from every view which is called in my controllers.

推荐答案

覆盖OnActionExecuting方法，添加whetever要添加到ViewBag

override OnActionExecuting method, add whetever you want to add to ViewBag

public class BaseController : Controller
{
    protected override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        ViewBag.someThing = "someThing"; //Add whatever
        base.OnActionExecuting(filterContext);
    }
}
