Hello i found the following script to get the culture info from the browser properties

public static CultureInfo ResolveCulture()
        {

            string[] languages = HttpContext.Current.Request.UserLanguages;

            if (languages == null || languages.Length == 0)
                return null;
            try
            {
                string language = languages[0].ToLowerInvariant().Trim();
                return CultureInfo.CreateSpecificCulture(language);
            }

            catch (ArgumentException)
            {
                return null;
            }
        }
        
        public static RegionInfo ResolveCountry()
        {
            CultureInfo culture = ResolveCulture();
            if (culture != null)

            return new RegionInfo(culture.LCID);
            return null;

        }

If i try to use it in XSLT i get the following error:

Extension function parameters or return values which have Clr type 'RegionInfo' are not supported.

Can someone please help?

I just want to get the language and use it in XSLT
