Mapping route & parameters in ASP.NET MVC

In Area VIPUsers I have controller ProfileController and other controllers.

If I want every method in ProfileController to have parameter (id) and every method in other controllers to have parameter (userid and id) how would I map it?

Would it be

context.MapRoute(
  "ProfileMapping",
  "VIPUsers/Profile/{action}/{id}",
  new {controller="ManageUsers", id=""}
);

and then map a default one for all the controllers?

context.MapRoute(
  "Default",
  "VIPUsers/{controller}/{action}/{userId}/{id}",
  new {action="Index", userId="", id = ""}
);

and...that's it? I see it's working but then it's weird...

If I go to a page on ProfileController and give it two parameters after {action} (VIPUsers/Profile/SomeAction/4/4/), it'd use the second mapped route. I开发者_如何学Pythons that correct?

thanks

and if I want the url to always require a UserId, how do I specify that?

The behavior you are seeing is correct. You will want to implement some route constraints to further narrow things down:
