Asp.net mvc html.routelink未转到指定的路由

我将一系列路线定义为：

routes.MapRoute(
                name: "ID",
                url: "{category}/{subcategory}/{lowercategory}/{lowercategory1}/{id}/{ignore}",
                defaults: new { controller = "Home", action = "Index", ignore = UrlParameter.Optional }
            );

            routes.MapRoute(
                name: "LowerCategory1",
                url: "{category}/{subcategory}/{lowercategory}/{lowercategory1}",
                defaults: new { controller = "Home", action = "Index" }
            );

            routes.MapRoute(
                name: "LowerCategory",
                url: "{category}/{subcategory}/{lowercategory}",
                defaults: new { controller = "Home", action = "Index" }
            );

            routes.MapRoute(
                name: "Subcategory",
                url: "{category}/{subcategory}",
                defaults: new { controller = "Home", action = "Index" }
            );

            routes.MapRoute(
                name: "Category",
                url: "{category}",
                defaults: new { controller = "Home", action = "Index" }
            );

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

现在我使用routeLink访问默认路由，但它不起作用

@Html.RouteLink("Create Ad", "Default", new { controller="Electronics",action="Details" })

请求转到主控台索引函数。我做错了什么。如何使用routeLink使请求转到默认路由。

我也遇到了这个问题。 代码似乎用签名调用RouteLink重载

RouteLink(string linkText, object routeValues, object htmlAttributes)

这意味着routeName永远不会使用此重载进行设置，并且很可能会得到一个带有空href属性的锚元素，或者使用默认控制器和操作生成的链接，因为RouteValue也没有设置为您期望的值

我们实际上想称之为重载

RouteLink(string linkText, string routeName, object routeValues)

这可以通过使用如下命名参数来确保：

@Html.RouteLink("Create Ad", routeName: "Default", routeValues: new { controller="Electronics",action="Details" })
