How to get route name from Attribute routing in ASP MVC5

Question

Does anyone know how to get the route name from Attribute routing in a action filter?

For example I have a controller and attribute route like this:

[HttpGet]
[CustomActionAttribute]
[Route("~/index", Name="IndexPage")]
public async Task<ActionResult> Index()
{
    //Controller logic
}

Is it possible to get route name in the CustomActionAttribute?

public override void OnActionExecuting(ActionExecutingContext filterContext)
{
    //Get the current route name here
}

You can extend RouteCollection to achieve this. You can find example code for this here

But that means I have to have a custom attribute route attribute?

After poking around the source code, I realized that the route name mapping is saved in a private field in RouteCollection class private Dictionary<string, RouteBase> _namedMap = new Dictionary<string, RouteBase>(StringComparer.OrdinalIgnoreCase); So I don't think we could access it. The only viable way would be create one for our own as you suggest it. Any other ideas?

From what I have read so far, It seems to be the least painful way.
