Question

routes.MapRoute(
                "top", // Route name
                "{controller}/Casestudy/{action}"
            );

Anyone know why this routing doesn’t resolve to;

/Auction/Casestudy/ABC/

The controller Auction is there, the Action ABC is there and the view is there?

Answer 1

My guess is that you put your "top" route after your "Default" route (provided you didn’t change that call to MapRoute()).

You need to ensure that your "top" route appears before you Default route, otherwise your "Default" route will surely match your tested URL and deliver a 404.

routes.MapRoute(
                "top", // Route name
                "{controller}/Casestudy/{action}"
            );

routes.MapRoute(
    "Default", // Route name
    "{controller}/{action}/{id}", // URL with parameters
    new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);

If those are switched up and your "Default" route comes first, then you’ll have your route matching the "Default" route with controller = "Auction", action = "Casestudy", id = "ABC". Which is obviously not the intention.
