Get Action name from URL inside ActionFilterAttribute

Question

I am writing custom filter attribute inherited from ActionFilterAttribute class in ASP.Net MVC. I want to get name of action from url, I tried

ControllerContext controllerContext = new ControllerContext();
controllerContext.RouteData.Values["action"].ToString();

but there is no item in controllerContext.RouteData.Values, hence giving me null reference error. Is any other way to get the same?

Try the following

    public override void OnActionExecuted(ActionExecutedContext filterContext)
    {

        string action = filterContext.ActionDescriptor.ActionName;
        string controller = filterContext.Controller.GetType().Name;

    }
