How do I redirect everything to a single controller?

Question

I have three specific routes:

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

    routes.MapRoute(
       "Admin Section",
       "AdminSection/{action}/{id}",
       new { controller = "AdminSection", action = "Index", id = UrlParameter.Optional }
       );

    routes.MapRoute(
       "Listings",
       "{controller}/{action}/{id}",
       new { controller = "Listings", action = "Index", id = UrlParameter.Optional }
       );

Basically, the first two routes work as planned, however, I want everything that isn't specifically in a route to be redirected to the listings controller.

I am still quite new to routing and have been trying to Google this for the past hour without any luck - I know exactly what is going on here, but, I don't know how to fix it.

I have used RouteDebugger, and I can see that it is hitting the route, but, the issue is that it will only go to the Listings controller if a controller is not specified - but, obviously there will always be something there.

I have tried a few different combinations - I thought I was on to a winner by removing the {controller} part of the URL and still defining the default value, but, I am not having much luck.

Does anyone know what I need to do?

Answer 1

How about this:

routes.MapRoute("Listings", "{action}/{id}", 
        new { controller = "Listings", action = "Index", id = UrlParameter.Optional });

site.com/test :

It'll go to action: test, controller: listing, id = blank

Edit: As I understand it you want a catch-all route.

routes.MapRoute("Listings", "{*url}",
    new { controller = "Listings", action = "Index" }
);

Original:

I can't test this at the moment but

routes.MapRoute(
   "Listings",
   "{anythingOtherThanController}/{action}/{id}",
   new { controller = "Listings", action = "Index", id = UrlParameter.Optional }
   );

This should work.

In your Listings controller, just accept a string parameter "anythingOtherThanController" and it will get bound to it.

The main problem here is that /some/action will be mapped to the same action as /another/action. So I'm not sure what you're trying to do here :)

Answer 3

Provide a default route and provide controller name as listings controller. Keep this route mapping at the bottom of all the mappings.

 routes.MapRoute(
   "Default",
   "{controller}/{action}/{id}",
   new { controller = "Listings", action = "Index", id = UrlParameter.Optional }
   );

Sorry I got sequence mixed.
