ASP.NET MVC routing returning null

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开发者_运维技巧 and action names. I get null returned - what am I missing?

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
});
