ASP.NET MVC Attribute & Conventional Routing not working

Question

I am trying to configure routing with both Conventional & Attribute based.

If I just use the default Conventional route included with MVC everything works. but if I add this Route attribute, I get a 404.

Here is the GET request URL: http://localhost:52386/Home/SimpleSearch?searchTerms=test&dateRange=0

Here is my RouteAttributes in Code:

[RoutePrefix("Home")] 
public class HomeController : Controller
{
    [Route("SimpleSearch/{searchTerms}/{dateRange}/{page?}")]
    [HttpGet]
    public ActionResult SimpleSearch(string searchTerms, DateRangeEnum dateRange, int page = 1)
    {
       //Code here
    }

}

Also the Route Config looks like this:

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapMvcAttributeRoutes();

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

I don't see what is wrong with this RouteAttribute, but even if something is wrong with it, why doesnt it fall back onto the default Conventional Route and work?

Answer 1

With the attribute route definition, you explicitly specified the route pattern to be

Home/SimpleSearch/{searchTerms}/{dateRange}/{page?}

So you should try to access your action method with same url pattern.

This should work.

 http://localhost:52386/Home/SimpleSearch/test/0

and Model binder will be able to map "test" to searchTerms parameter and 0 to dateRange parameter.

Your conventional (explicitly using querystring) will not work when you have an attribute route with a different pattern
