ASP.NET MVC – Catch All Route And Default Route

by

Use route constraints

In your case you should define your default route {controller}/{action}/{id} and put a constraint on it. Probably related to controller names or maybe even actions. Then put the catch all one after it and it should work just fine.

So when someone would request a resource that fails a constraint the catch-all route would match the request.

So. Define your default route with route constraints first and then the catch all route after it:

routes.MapRoute(
    "Default",
    "{controller}/{action}/{id}",
    new { controller = "Home", action = "Index", id = UrlParameter.Optional },
    new { controller = "Home|Settings|General|..." } // this is basically a regular expression
);
routes.MapRoute(
    "NotFound",
    "{*url}",
    new { controller = "Error", action = "PageNotFound" }
);
