Get controller and action name from within controller?

Simple and easiest way to get controller name in MVC are

string actionName = this.ControllerContext.RouteData.Values["action"].ToString();
string controllerName = this.ControllerContext.RouteData.Values["controller"].ToString();

var routeValues = HttpContext.Current.Request.RequestContext.RouteData.Values;
if (routeValues != null) 
{
    if (routeValues.ContainsKey("action"))
    {
        var actionName = routeValues["action"].ToString();
                }
    if (routeValues.ContainsKey("controller"))
    {
        var controllerName = routeValues["controller"].ToString();
    }
}
