Asp.net mvc 4 asp mvc友好url路由问题

我将下一个MapRoute添加到我的RouteConfig：

 routes.MapRoute(
            name: "Noticias",
            url: "{controller}/{action}/{id}/{urlAmiga}",
            defaults: new
                {
                    controller = "Noticias",
                    action = "Noticia",
                    id = "",
                    urlAmiga = ""
                }
            );

鉴于此，我有以下几点：

 <a href="<%= Url.Action("Noticia","Noticias", new {id = item.IdNoticia, urlAmiga="this-is-a-test" }) %>">
                                <h5>
                                    <%= item.Titulo %>
                                </h5>
                            </a>

我希望生成的链接如下所示：

但是，结果是：

为什么？

确保在默认路线之前已声明此路线：

routes.MapRoute(
    name: "Noticias",
    url: "{controller}/{action}/{id}/{urlAmiga}",
    defaults: new
    {
        controller = "Noticias",
        action = "Noticia",
        id = "",
        urlAmiga = ""
    }
);

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

显示所有路线。现在就像下面的答案一样，在我改变顺序之前继续，我把它移到了第一位，正如你所说的，但它还不起作用。我在RegisterRoutes方法中设置了一个断点，我可以看到它没有触发，我不知道是否可能与此有关。。。

routes.MapRoute(
    name: "Noticias",
    url: "{controller}/{action}/{id}/{urlAmiga}",
    defaults: new
    {
        controller = "Noticias",
        action = "Noticia",
        id = "",
        urlAmiga = ""
    }
);

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