How can I redirect my action to the root of the web site?

Question

I have the following code in my controller to redirect my user after he has logged out:

public ActionResult Logout()
        {
            FormsAuthentication.SignOut();
            return new RedirectToRouteResult(
                new RouteValueDictionary(
                    new {
                        area = "Administration",
                        controller = "Menus", 
                        action = "Home" 
                    }
                )
            );
        }

I would like to redirect the user to / or the base URL (root) of my site. Is there a way that I can do this without having to give details of the area, controller and action?

Solution

if you don't want to use RedirectToAction (for me is the right choice) you can use

return Redirect(Url.Content("~/"));

UPDATE

As stated in the comments, this should also works

return Redirect("~/");

Url.Content should not be required. You can just do: return Redirect("~");

Perfect solution! Works great when using MVC Areas too unlike trying to use RedirectToAction("Default");

@CurtisYallop I had to do return Redirect("~/");
