Resolving routing provided that incorrect pairs locale - localisation

[manst]

Hello, In RouteLocalization.Mvc.Sample

/en/Welcome => culture: en, Contoller: Home, Action: Index /de/Willkommen => culture: de, Contoller: Home, Action: Index /en/Willkommen => 404 /de/Welcome => 404

Сan I made to work if incorrect pairs locale - localisation: /en/Willkommen => culture: en, Contoller: Home, Action: Index /de/Welcome => culture: de, Contoller: Home, Action: Index

Thank You, Yuriy

Hi,

it is not really supported, but you can do it like this:

Since RouteLocalization does not add the culture as parameter (its a fixed string), you would have to disable AddCultureAsRoutePrefix:

configuration.AddCultureAsRoutePrefix = false;

Then add the culture parameter manually to the route:

[RoutePrefix("{culture}")]
public partial class HomeController : Controller
{

And create your own culture detection filter:

public class CustomFilter : CultureSensitiveActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext context)
    {
        // Check for RouteData
        if (context.RouteData.Values["culture"] == null)
        {
            return;
        }

        // Get RouteData
        string cultureName = (string)context.RouteData.Values["culture"];

        // Set culture
        CultureInfo cultureInfo = new CultureInfo(cultureName);

        // Try to override to region dependent browser culture
        if (TryToPreserverBrowserRegionCulture)
        {
            if (AcceptedCultures.Count == 0)
            {
                throw new InvalidOperationException("TryToPreserverBrowserRegionCulture can only be used in combination with AcceptedCultures.");
            }

            cultureInfo =
                Localization.DetectCultureFromBrowserUserLanguages(
                    new HashSet<string>(AcceptedCultures.Where(culture => culture.StartsWith(cultureInfo.Name))), cultureInfo.Name)(
                        context.HttpContext.ApplicationInstance.Context);
        }

        if (SetCurrentCulture)
        {
            Thread.CurrentThread.CurrentCulture = cultureInfo;
        }

        if (SetCurrentUICulture)
        {
            Thread.CurrentThread.CurrentUICulture = cultureInfo;
        }
    }
}

Which you can then use like the original one:

GlobalFilters.Filters.Add(new CustomFilter()
{
    // Set this options only if you want to support detection of region dependent cultures
    // Supports this use case: https://github.com/Dresel/RouteLocalization/issues/38#issuecomment-70999613
    AcceptedCultures = acceptedCultures,
    TryToPreserverBrowserRegionCulture = true
});

Hope that helps.
