Asp.net MVC路由模糊,同一页面的两条路径

public static void RegisterRoutes(RouteCollection routes)
{
    routes.MapRoute(
        name: "Route1",
        url: "home/index/{id}",
        defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    );

    routes.MapRoute(
        name: "Route2",
        url: "home/index/{name}",
        defaults: new { controller = "Home", action = "Index", name = UrlParameter.Optional }
    );
}

public ActionResult Index(int? id, string name)
{
    if (id.HasValue)
    {
        // Handle the first route
    }
    else if (!string.IsNullOrEmpty(name))
    {
        // Handle the second route
    }
    else
    {
        // Handle the default case
    }
}
