c# - How to route a multiple language URL with a MVC

Question

I need multi-language URL route of existing controller. Let me explain more:

I have a controller with name "Product" and View with name "Software"; therefore, by default if the user enters "http://example.com/en/Product/Software", get right content (that really exists in http://example.com/Product/Software),

However, if another user -- a French user -- types "http://example.com/fr/Produits/logiciels", must get above controller and show with right content (same http://example.com/Product/Software but with French text).

Note: I set the route table with "{language}/{controller}/{action}/{id}"

Any other invalid URL must show the 404 page.

Is it possible?

Building upon Dan's post, I'm using the beneath for translating my controller and action names.

I created a table to store the values, this could and probably should be held in the resource files to keep everything together; however I used a database table as it works better with my companies processes.

CREATE TABLE [dbo].[RoutingTranslations](
[RouteId] [int] IDENTITY(1,1) NOT NULL,
[ControllerName] [nvarchar](50) NOT NULL,
[ActionName] [nvarchar](50) NOT NULL,
[ControllerDisplayName] [nvarchar](50) NOT NULL,
[ActionDisplayName] [nvarchar](50) NOT NULL,
[LanguageCode] [varchar](10) NOT NULL)

The RouteConfig.cs file was then changed to:

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

        //Build up routing table based from the database.  
        //This will stop us from having to create shedloads of these statements each time a new language, controller or action is added
        using (GeneralEntities db = new GeneralEntities())
        {
            List<RoutingTranslation> rt = db.RoutingTranslations.ToList();
            foreach (var r in rt)
            {
                routes.MapRoute(
                    name: r.LanguageCode + r.ControllerDisplayName + r.ActionDisplayName,
                    url: r.LanguageCode + "/" + r.ControllerDisplayName + "/" + r.ActionDisplayName + "/{id}",
                    defaults: new { culture = r.LanguageCode, controller = r.ControllerName, action = r.ActionName, id = UrlParameter.Optional },
                    constraints: new { culture = r.LanguageCode }
                );
            }                
        }

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

    }
}

By default this will always use the English controller and action names, but allows you to provide an override by entering the values into the table.
