是否可以在运行时动态指定动作名称？

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

public class MyRouteHander : IRouteHandler
{
    public IHttpHandler GetHttpHandler(RequestContext requestContext)
    {
        var rd = requestContext.RouteData;
        var action = rd.GetRequiredString(\"action\");
        var controller = rd.GetRequiredString(\"controller\");
        if (string.Equals(action, \"users\", StringComparison.OrdinalIgnoreCase) &&
            string.Equals(controller, \"home\", StringComparison.OrdinalIgnoreCase))
        {
            // The action name is dynamic
            string actionName = \"Index\";
            requestContext.RouteData.Values[\"action\"] = actionName;
        }
        return new MvcHandler(requestContext);
    }
}

routes.MapRoute(
    \"Default\",
    \"{controller}/{action}/{id}\",
    new { controller = \"Home\", action = \"Index\", id = UrlParameter.Optional }
).RouteHandler = new MyRouteHander();

/home/users

Home

Index
