ASP.net MVC support for URL's with hyphens

Question

Is there an easy way to get the MvcRouteHandler to convert all hyphens in the action and controller sections of an incoming URL to underscores as hyphens are not supported in method or class names.

This would be so that I could support such structures as sample.com/test-page/edit-details mapping to Action edit_details and Controller test_pagecontroller while continuing to use MapRoute method.

I understand I can specify an action name attribute and support hyphens in controller names which out manually adding routes to achieve this however I am looking for an automated way so save errors when adding new controllers and actions.

C# version of John's Post for anyone who would prefer it: C# and VB version on my blog

public class HyphenatedRouteHandler : MvcRouteHandler{
        protected override IHttpHandler  GetHttpHandler(RequestContext requestContext)
        {
            requestContext.RouteData.Values["controller"] = requestContext.RouteData.Values["controller"].ToString().Replace("-", "_");
            requestContext.RouteData.Values["action"] = requestContext.RouteData.Values["action"].ToString().Replace("-", "_");
            return base.GetHttpHandler(requestContext);
        }
    }

...and the new route:

routes.Add(
            new Route("{controller}/{action}/{id}", 
                new RouteValueDictionary(
                    new { controller = "Default", action = "Index", id = "" }),
                    new HyphenatedRouteHandler())
        );

You can use the following method too but bear in mind you would need to name the view My-Action which can be annoying if you like letting visual studio auto generate your view files.

[ActionName("My-Action")]
public ActionResult MyAction() {
    return View();
}
