How to create a route without action?

Is it possible to create a route without action?

I have this default route:

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

But I also I want to have URLs like this: http://mysite/bar/1234 where 1234 is the ID and bar is the controller.

So I created the following route:

routes.MapRoute(
    name: "BarRoute",
    url: "{controller}/{id}",
    defaults: new { controller = "bar", action = "Index", id = UrlParameter.Optional }
);

But when I navigate to http://mysite/bar/1234, it said the resource is not found. What did I do wrong in the second route?

routes.MapRoute(
  name:        "BarRoute",
  url:         "{controller}/{id}",
  defaults:    new { controller = "Bar", action = "Index" },
  constraints: new { id = @"\d+" }
);

You have to take into account that your route has to be placed in appropriate place - before the more general routes, for example:

routes.MapRoute(
           name: "BarRoute",
routes.MapRoute(
           name: "Default",

You cannot have the following 2 routes in that order without any constraints

  • {controller}/{action}/{id}
  • {controller}/{id}

Those 2 routes are incompatible. When you attempt to access http://mysite/bar/1234, the routing engine is analyzing your routes and /bar/1234 matches your first route. Except that I guess you do not have an action called 1234 on the Bar controller.

So if you want this setup to work you need to specify some constraints. Also don't forget that the order of your routes definition is important because they are resolved in the order you defined them. So make sure you place more specific routes at the top.
