How can I get the route name in controller in ASP.NET MVC?

by

The route name is not stored in the route unfortunately. It is just used internally in MVC as a key in a collection. I think this is something you can still use when creating links with HtmlHelper.RouteLink for example (maybe somewhere else too, no idea).

Anyway, I needed that too and here is what I did:

public static class RouteCollectionExtensions
{
    public static Route MapRouteWithName(this RouteCollection routes,
    string name, string url, object defaults, object constraints)
    {
        Route route = routes.MapRoute(name, url, defaults, constraints);
        route.DataTokens = new RouteValueDictionary();
        route.DataTokens.Add("RouteName", name);

        return route;
    }
}

So I could register a route like this:

routes.MapRouteWithName(
    "myRouteName",
    "{controller}/{action}/{username}",
    new { controller = "Home", action = "List" }
    );

In my Controller action, I can access the route name with:

RouteData.DataTokens["RouteName"]

Hope that helps.
