Multiple Routes on a Controller

问题:

Was wondering if it was possible to have more than one route pointing to a WebApi controller?

For example I will like to have both http://domain/calculate and http://domain/v2/calculate pointing to the same controller function?

public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API configuration and services
            // Configure Web API to use only bearer token authentication.
            config.SuppressDefaultHostAuthentication();
            config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType));

            // Web API routes
            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(
                name: "route1",
                routeTemplate: "calculate",
                defaults: new { controller = "Calculator", action = "Get" });

            config.Routes.MapHttpRoute(
                name: "route2",
                routeTemplate: "v2/calculate",
                defaults: new { controller = "Calculator", action = "Get" });

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
        }
    }

OR

public class CalculatorController: ApiController
{
    [Route("calculate")]
    [Route("v2/calculate")]
    public String Get() {
        return "xxxx";
    }
}
