值未在url中传递

Question

 //In Controller this is what I have 
 public class AjaxController : Controller
 {

    [AcceptVerbs(new string[]{"GET"})]
    public ActionResult FindRooms(string selectedBuilding)
    {
        return Json(new { Room = "x"}, JsonRequestBehavior.AllowGet);
    }

 }

 //In Global.asax.cs I have  
 routes.MapRoute
 (
     "AjaxRoute1",
     "Ajax/FindRooms/{selectedBuilding}",
     new { controller = "Ajax", action = "FindRooms", selectedBuilding = "" }
 );

如果我浏览到URL localhost / Ajax / FindRooms / SOMEBUILDING。 SOMEBUILDING未传递给FindRooms方法的selectedBuilding参数。它总是空的？我如何解决这个问题，以便它在POST和GET中都有效？

正如TA先生建议其他路线影响这一点。路由的顺序很重要。

我把默认的路线路线放在最后，就像一个魅力。!!

        routes.MapRoute
        (
           "AjaxRoute1",
           "Ajax/FindRooms/{selectedBuilding}",
           new { controller = "Ajax", action = "FindRooms", selectedBuilding = "" }
        );

        routes.MapRoute
        (
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Home", action = "Index", id = UrlParameter.Optional }

        );
