How to get Action and Controller name in ASP.Net Core MVC app?

Question

How to get Action and Controller names in ASP.Net MVC Core RC1 Application in Startup.cs?

I want to create a middleware and log the information (I want to Log detailed response to my Database, so I need Action and Controller info.) after following code in configure method of startup.cs -

 app.UseMvc(routes =>
{
     routes.MapRoute(
            name: "default",
            template: "{controller=User}/{action=Index}/{id?}");
 });

//Want to get Action and controller names here..

Answer 1

You'll want to inject the IActionDescriptorCollectionProvider service into your middleware. From that, you can use the property ActionDescriptors.Items to get a list of ActionDescriptor, which has all the route values for that action. If you cast that to ControllerActionDescriptor, you'll have access to ControllerName and ActionName.
