ASP.NET MVC routing returning null

Question

I am trying to get a URL for the following route:

RouteTable.Routes.MapRoute(
    null,
    "cinema",
    new
{
    Controller = "CinemaListings",
    Action = "ShowCinemaLandingPage",
    SiteArea = "CinemaTimes",
    MainLandingPage = true
});

I've tried the following methods to produce the URL:

<%:Url.Action("ShowCinemaLandingPage", "CinemaTimes", new { SiteArea = "CinemaTimes", MainLandingPage = true})%>
<%:Url.RouteUrl(new { Controller = "CinemaTimes", Action = "ShowCinemaLandingPage", SiteArea = "CinemaTimes", MainLandingPage = true })%>

I've also tried with only the controller and action names. I get null returned - what am I missing?

What 'type' is SiteArea? Is it a string parameter? Can you show us the controller/action with parameters that this maps to? — George Stocker

Doesn't this work?

<%:Url.Action("ShowCinemaLandingPage", "CinemaListings", new { SiteArea = "CinemaTimes", MainLandingPage = true })%>

It seems from your code that you've mixed up SiteArea with Controller values. So instead of providing controller name in Url.Action, you've provided SiteArea twice (as second parameter and as additional route value).

It is hard to understand your route. First of all, you have not given it name (passing null which I have experienced before causing problem) and then there is no place holder in there.

This cannot work without giving it a controller.

<%:Url.Action("ShowCinemaLandingPage", "CinemaTimes", new { SiteArea = "CinemaTimes", MainLandingPage = true})%>

Here you are passing controller name but since there is no controller name, no path will be matched.

So I would use - at bare minimum - this:

RouteTable.Routes.MapRoute(
    "GiveMeSomeNameWillYa?",
    "{Controller}/{Action}",
    new
{
    Controller = "CinemaListings",
    Action = "ShowCinemaLandingPage",
    SiteArea = "CinemaTimes",
    MainLandingPage = true
});

The route does work for incoming requests. Any requests to /cinema will be handled by the ShowCinemaLandingPage on the CinemaListings controller. I need to maintain this behaviour. I've tried adding the route name but this had no effect.

-1 Route name is completely optional. The URL template doesn't require controller and action tokens, if these are provided with default values.
