How to enumerate Areas in ASP.NET MVC 2 RC

My controller has to enumerate all the areas in the application. Is it possible? 开发者_如何学PythonAnd how?

From this issue, something like that =>

RouteTable.Routes.OfType<Route>()
            .Where(r => r.DataTokens != null)
            .Select(r => (string) r.DataTokens["area"]);
