MVC Route with Optional Section

I would like to create a route for my MVC page that looks like this:

/Articles/

/Articles/Page/2

/Articles/Page/3

I want the default page to be 1, but if the page is 1, then don't actually show the /Page/ piece.

I started out with:

routes.MapRoute(
    "Articles",
    "Articles/Page/{page}开发者_Go百科",
            new { controller = "Articles", action = "Index", page = 1 }
);

The problem with this is that when I do:

 <%= Html.RouteLink("Articles", new { page = 1 }) %>

My route ends up being: /Articles/Page/

You might need two route definitions for this (untested):

routes.MapRoute(
    "ArticlesDefault",
    "Articles",
    new { controller = "Articles", action = "Index", page = 1 }
);

routes.MapRoute(
    "Articles",
    "Articles/Page/{page}",
    new { controller = "Articles", action = "Index" }
);

and your controller action:

public ActionResult Index(int page)
{
    ...
}

Put both in:

// This will match routes where the page equals one. Since the page can't
// be specifed here, it will drop to the next one for page values other
// than 1.
routes.MapRoute("Articles",
                "Articles",
                new { controller = "Articles", action = "Index", page = 1 } 
); 

// This route handles pages other than 1
routes.MapRoute(null,
                "Articles/Page/{page}",
                new { controller = "Articles", action = "Index" }
); 

You don't need to do anything with the controller.
