How do I get Route name from RouteData?

Question

I have several routes defined in my Global.asax;

When I\'m on a page I need to figure out what is the route name of the current route, because route name drives my site

Answer 1

RouteCollection maintains a private dictionary of named routes.

Route names can be coaxed out of it by

1. using reflection to retrieve the value of the private field and
2. querying the dictionary for the item whose value is the route.

The extension method below follows this process:

public static string Name(this RouteBase original)
{
    var routes = System.Web.Routing.RouteTable.Routes;

    if (routes.Contains(original))
    {
        var namedMapField = routes.GetType().GetField("_namedMap", BindingFlags.NonPublic | BindingFlags.Instance);
        var namedMap = namedMapField.GetValue(routes) as Dictionary;

        var query = 
            from pair in namedMap 
            where pair.Value == original 
            select pair.Key;

        return query.Single();
    }

    return string.Empty;
}
