ASP.Net MVC路由问题url无法正常工作

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

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

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }
}

public class ProductController : Controller
{
    public ActionResult Details(int id)
    {
        return View();
    }
}

public class ProductController : Controller
{
    [Route("product/{id:int}")]
    public ActionResult Details(int id)
    {
        return View();
    }
}

public class ProductController : Controller
{
    [Route("product/{id:int}", Order = 1)]
    public ActionResult Details(int id)
    {
        return View();
    }

    [Route("product/{name}", Order = 2)]
    public ActionResult Details(string name)
    {
        return View();
    }
}

public class ProductController : Controller
{
    [Route("product/{id:int}")]
    public ActionResult Details(int id)
    {
        return View();
    }
}
