I'm currently facing an issue with my code related to the way CultureInfo.GetCultures method is sending me the list of countries.

I have this in my getCountries method:

System.Threading.Thread.CurrentThread.CurrentCulture = new CultureInfo("en-GB"); 
System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-GB"); 
var cultures = CultureInfo.GetCultures(CultureTypes.SpecificCultures);

Which retrieves me a list of Cultures in associated to English Culture.

I was trying to do something like

public List<String> getCountriesNamesbyCountry(string countrycode){

    System.Threading.Thread.CurrentThread.CurrentCulture = new CultureInfo(countrycode); 
    System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo(countrycode); 
    var cultures = CultureInfo.GetCultures(CultureTypes.SpecificCultures);

    var cultureList = new List<String>();

       foreach (CultureInfo cul in cultures)
            var country = new RegionInfo(cul.LCID);

            if (!cultureList.Contains(country.DisplayName))

        return cultureList;

If I try to do this

List<String> en = getCountriesNamesbyCountry("en");
List<String> es = getCountriesNamesbyCountry("es");

Both lists will give me a list of country names in english.
What am I doing wrong >.<?

Build a resource yourself, which you can then include and use in your application. Perhaps you can find one online. There must've been more people facing this issue.
