Url.RouteUrl返回null，MVC5？

Question

我有以下RouteConfig：

routes.MapRoute(
    "CompareDevicesByPage",
    "ComparedDevices/{id}/{sortingType}/{sortingDirection}/{searchText}/{page}",
    new { controller = "Compare", action = "Page", id = UrlParameter.Optional, sortingType = UrlParameter.Optional, sortingDirection = UrlParameter.Optional, searchText = UrlParameter.Optional, page = UrlParameter.Optional }
);

routes.MapRoute(
    "ManufacturerDevices",
    "Manufacturer/{objectName}/{id}/{title}/{sortingType}/{sortingDirection}/{searchText}/{page}",
    new { controller = "Manufacturer", action = "Devices", title = UrlParameter.Optional, page = UrlParameter.Optional, sortingType = UrlParameter.Optional, sortingDirection = UrlParameter.Optional, searchText = UrlParameter.Optional }
);

每当我使用Url.RouteUrl时，它都会返回null。

Url.RouteUrl("CompareDevicesByPage", new { id = 0, page = 1, sortingType = (short)DevicesSortingEnum.Popular, sortingDirection = (int)SortDirection.Descending, searchText = "" })

出了什么问题？

我发现了问题，
我必须将地图路线更改为以下内容：

routes.MapRoute(
    "CompareDevicesByPage",
    "ComparedDevices/{id}/{sortingType}/{sortingDirection}/{page}/{searchText}",
    new { controller = "Compare", action = "Page", id = UrlParameter.Optional, sortingType = UrlParameter.Optional, sortingDirection = UrlParameter.Optional, searchText = UrlParameter.Optional, page = UrlParameter.Optional }
);

routes.MapRoute(
    "ManufacturerDevices",
    "Manufacturer/{objectName}/{id}/{title}/{sortingType}/{sortingDirection}/{page}/{searchText}",
    new { controller = "Manufacturer", action = "Devices", title = UrlParameter.Optional, page = UrlParameter.Optional, sortingType = UrlParameter.Optional, sortingDirection = UrlParameter.Optional, searchText = UrlParameter.Optional }
);
