问题描述

如何在我所有的视图中访问某些ViewBag属性?我想获得一些信息，例如当前用户名等，可在任何地方访问，但不必在我的项目中的每个ActionResult方法中专门定义属性

How can I access some ViewBag properties across all my views? I want to have some information like current user name, etc accessible everywhere, but without having to to specifically define the properties in each ActionResult method on my project

推荐答案

达到要求的最佳，直接的方法是制作一个自定义基础控制器"并从该基础控制器继承您的控制器.

The best and straight forward way to accomplish your requirement is to make a Custom Base Controller and inherit your Controller from this Base Controller.

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

现在，代替继承Controller类，在控制器中继承MyBaseController，如下所示:-

Now instead of inheriting Controller class,inherit MyBaseController in your Controller as shown :-

public class MyOtherController : MyBaseController
{
    public ActionResult MyOtherAction()
    {
       //Your Stuff
       return View();
    }
    //Other ActionResults
}
