Route prefix is not working with index

Question

I have controller: DoomPlaceController

In route: I have used: doom-place/{parameter} // no action

and In controller :

[Route("doom-place/{parameter}")]
public ActionResult Index(string parameter)
{
    return View(); 
}

What I want: when I hit URL: www.xyz.com/doom-place it should open Doom-Place/index page.

But right now, I am able to access the page with doom-place/index but I want when I hit www.xyz.com/doom-place, it will automatically open index page.

Help will be appreciated.

Answer 1

You can make the parameter optional

[RoutePrefix("doom-place")]
public class DoomPlaceController : Controller {
    //Matches GET /doom-place
    //Matches GET /doom-place/some_parameter
    [HttpGet]
    [Route("{parameter?}")]
    public ActionResult Index(string parameter) { 
        return View(); 
    }
}

Given that attribute routing is being used, the assumption is that attribute routing has been enabled in RouteConfig.RegisterRoutes

public static void RegisterRoutes(RouteCollection routes) {
    routes.IgnoreRoute(“{resource}.axd/{*pathInfo}”);

    //enable attribute routing     
    routes.MapMvcAttributeRoutes();

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