如何重定向到特定的动作路线

Question

this is my custom route.but when I want to use RedirectToAction("action","controller"); it cause error. No route in the route table matches the supplied values. I visited some related post but I could not solve it. How do I can fix it?

routes.MapMvcAttributeRoutes();
routes.LowercaseUrls = true;
routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}/{filter1}/{filter2}/{filter3}/{filter4}/{filter5}/{filter6}/{filter7}/{filter8}/{filter9}/",
    defaults: new
    {
        controller = "Shop",
        action = "Category",
        id = UrlParameter.Optional,
        filter1 = UrlParameter.Optional,
        filter2 = UrlParameter.Optional,
        filter3 = UrlParameter.Optional,
        filter4 = UrlParameter.Optional,
        filter5 = UrlParameter.Optional,
        filter6 = UrlParameter.Optional,
        filter7 = UrlParameter.Optional,
        filter8 = UrlParameter.Optional,
        filter9 = UrlParameter.Optional,
    }
);

I had a similar problem once with RedirectToAction and found out that you need a valid route registered that leads to that action. in your case, the error occurred because your optional parameter is more than expected amount.

I test code and it works :

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}/{filter1}/{filter2}",
    defaults: new
    {
        controller = "Employees",
        action = "Index",
        id = UrlParameter.Optional,
        filter1 = UrlParameter.Optional,
        filter2 = UrlParameter.Optional
    }
);

if you want your own route you can use [Route("")] on top of your Action, at the first Add routes.MapMvcAttributeRoutes(); to RegisterRoutes method in RouteConfig.cs . After that do like below:

[Route("{TestEmployee}/{Index}/{id?}/{filter1?}/{filter2?}/{filter3?}/{filter4?}/{filter5?}/{filter6?}/{filter7?}/{filter8?}/{filter9?}")]
public ActionResult Index()
{
    //do something 
}

then you can redirectToAction :

return RedirectToAction("Index", "TestEmployee" ,routeValues: null);
