Areas-Controller-Action Listing for URL Authorize

var areas = Assembly.GetExecutingAssembly().GetTypes().Where(type => typeof(AreaRegistration).IsAssignableFrom(type)).ToList();
foreach(var area in areas)
{
var controllers = Assembly.GetExecutingAssembly().GetTypes().Where(type => typeof(Controller).IsAssignableFrom(type)).ToList();
foreach (var controller in controllers)
{
var methods = controller.GetMethods(BindingFlags.Public | BindingFlags.Instance);
foreach (var method in methods)
{
if (method.ReturnType == typeof(ActionResult))
{
lstControllerActions.Add(string.Format("Area -> Controller -> Action : {0} -> {1} -> {2}", area.Name, controller.Name, method.Name));
}
}
}
}

this problem is solved. quotation from @kamal-hamidi, thanks.
