Avoid hard-coding controller and action names

Question

ASP.NET MVC seems to be encouraging me to use hard-coded strings to refer to controllers and actions.

For example, in a controller:

return RedirectT

Not sure if somebody already added an extension method to one of the ASP.NET MVC related projects but here's a piece of code that you can use to create your own extension method:

public RedirectToRouteResult RedirectToAction(Expression> action, RouteValueDictionary routeValues) where TController : Controller
    {
        RouteValueDictionary rv = Microsoft.Web.Mvc.Internal.ExpressionHelper.GetRouteValuesFromExpression(action);

        return RedirectToAction((string)rv["Action"], (string)rv["Controller"], routeValues ?? new RouteValueDictionary());
    }

    public ActionResult Index()
    {
        return RedirectToAction(x => x.Index(), null);
    }

There's no parameters merging logic, so you'll have to add it by your own.

UPDATE: @mccow002 added a similar solution a few seconds before me, so I think his solution should be accepted.
