c# - HttpVerbs.Get とパラメーター?

Question

私は次のアクションを持っています:

public class IntegrationController : Controller
    {
        [AcceptVerbs(HttpVerbs.Get)]
        public ContentResult Feed(string feedKey)
        {
           ...
        }
}

この URL を使用しようとしました:

http://MyServer/Integration/Feed/MyTest 

しかしfeedKey、ヌルですか？これはルートと関係がありますか？

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                "Default", // Route name
                "{controller}/{action}/{id}", // URL with parameters
                new { controller = "Ad", action = "List", id = UrlParameter.Optional } // Parameter defaults
            );

            routes.MapRoute(
                "TreeEditing", // Route name
                "{controller}/{action}/{name}/{id}", // URL with parameters
                new { controller = "AdCategory", action = "Add", name = string.Empty, id = -1 }
            );
