This seems to work nicely for me (so far), also works if you are using attribute routing.

<pre><code>public class BaseController : Controller
{
 protected string CurrentAction { get; private set; }
 protected string CurrentController { get; private set; }

 protected override void Initialize(RequestContext requestContext)
 {
 this.PopulateControllerActionInfo(requestContext);
 }

 private void PopulateControllerActionInfo(RequestContext requestContext)
 {
 RouteData routedata = requestContext.RouteData;

 object routes;

 if (routedata.Values.TryGetValue("MS_DirectRouteMatches", out routes))
 {
 routedata = (routes as List&lt;RouteData&gt;)?.FirstOrDefault();
 }

 if (routedata == null)
 return;

 Func&lt;string, string&gt; getValue = (s) =&gt;
 {
 object o;
 return routedata.Values.TryGetValue(s, out o) ? o.ToString() : String.Empty;
 };

 this.CurrentAction = getValue("action");
 this.CurrentController = getValue("controller");
 }
}
</code></pre>

blocks|key|258772|text|为什么不做一些简单的事情呢？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|258773|只需调用Request.Path，它将返回一个以"/“分隔的字符串|offset|length|style|CODE|258774|然后，您可以使用.Split('/')[1]来获取控制器名称。|258775|​|258776|📷|atomic|258777|258778|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://ask.qcloudimg.com/http-save/yehe-900000/f124cc554b1896f8f05896e5a35040cb.png|imageAlt^0|0|4|C|0|8|E|0|0|0|1|0|0|0^^$0|@$1|2|3|4|5|6|7|Y|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Z|8|@$D|10|E|11|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|12|8|@$D|13|E|14|F|G]]|9|@]|A|$]]|$1|J|3|K|5|6|7|15|8|@]|9|@]|A|$]]|$1|L|3|M|5|N|7|16|8|@]|9|@$D|17|E|18|1|19]]|A|$]]|$1|O|3|K|5|6|7|1A|8|@]|9|@]|A|$]]|$1|P|3|-4|5|6|7|1B|8|@]|9|@]|A|$]]]|Q|$R|$5|S|T|U|A|$V|W|X|-4]]]]

Why not having something simpler?

Just call <code>Request.Path</code>, it will return a String Separated by the "/"

and then you can use <code>.Split('/')[1]</code> to get the Controller Name.

Here is the simplest and most practical answer to getting a name:

<pre><code>var actionName = RouteData.Values["action"];
var controllerName = RouteData.Values["controller"];

Or

<pre><code>string actionName = RouteData.Values["action"].ToString();
string controllerName = RouteData.Values["controller"].ToString();

Code above tests with asp.net mvc 5.

For our web application I need to save the order of the fetched and displayed items depending on the view - or to be precise - the controller and action that generated the view (and the user id of course, but that's not the point here).
Instead of just giving an identifier myself in each controller action (in order to use it for some view-dependant sorting of DB outputs), I thought that it would be safer and easier to create this identifier automatically from the controller and action method it gets called from.
How can I get the name of the controller and action from within the action method in a controller? Or do I need reflection for that?

Get controller and action name from within controller?

路由

对于我们的web应用程序，我需要根据视图-或者更准确地说-生成视图的控制器和操作(当然还有用户id，但这不是这里的重点)保存获取和显示的项的顺序。与其自己在每个控制器操作中给出一个标识符(以便使用它对DB输出进行一些与视图相关的排序)，我认为从从中调用它的控制器和操作方法自动创建这个标识符会更安全、更容易。如何从控制器...
