您不能通过属性路由来做到这一点，请通过MVC4方式做到这一点:

You can't do this with Attribute routing, do this the MVC4 way:

像这样在您的routemapper中映射一条路线:

Map a route in your routemapper like this:

routes.MapRoute("RouteName","{*url}",new { controller = "YourFancyController", action = "YourAction" });

这将是您的全部路线.

如果您想将所有路由映射到其控制器，则可以执行以下操作:

If you would like to map all the routes to their controller you can do this:

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

    routes.MapMvcAttributeRoutes();

    AreaRegistration.RegisterAllAreas();

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