Asp.net mvc 3 url.Action和Html.ActionLink生成的url不正确

我有以下路线：

routes.MapRoute(
    "NewsRoute",
    "News/{newsId}/{newsTitle}",
    new {
        controller = "News",
        action = "News",
        newsId = UrlParameter.Optional,
        newsTitle = UrlParameter.Optional
    }
);
routes.MapRoute(
    "Default", // Route name
    "{controller}/{action}/{id}", // URL with parameters
    new { controller = "Home", action = "Home", id = UrlParameter.Optional } // Parameter defaults
);

使用方法：

@Url.Action("News", "News", new { newsId = "", newsTitle = "" })

我希望有“/News”url，但正在生成“/News/News”。我想是使用了默认路线。

所以问题是为什么跳过新闻路线？

解决方案是使用两个可选参数和操作将路线拆分为两个单独的操作：

routes.MapRoute(
    "NewsRoute",
    "News", new {
        controller = "News",
        action = "Index"
    }
);

routes.MapRoute(
    "Specific News",
    "News/{id}/{title}",
    new {
        controller = "News",
        action = "News",
        title = UrlParameter.Optional
    }
);

);

routes.MapRoute(

看起来像2个禁止使用的可选辅助设备看起来像2个禁止使用的可选辅助设备
