Finding a Culture with the same Language

Question

I am working on a globalization project using .resx resourse files. I have some fallback logic in case the language that the user selected doesn't have a resx file. Is there a way to find a culture that has the same language but a different region than a supplied culture?

Answer 1

Resources that are specific to a language, but not to a specific culture, should be in their own file, e.g. if you have the following resource files:

Resources.resx
Resources.en.resx
Resources.fr.resx
Resources.fr-FR.resx

(language-invariant strings in Resources.resx, French strings in Resources.fr.resx, and France-specific French strings in Resources.fr-FR.resx)

And the user's culture is fr-CA (Canadian French), then it will use resources from the following files, in this order:

Resources.fr.resx
Resources.resx

This is the default resource behavior.

Answer 2

If I understand you correctly then you're looking for something like cultures with same languages

var culture = new CultureInfo("fr");
var sameLanguageCultures = CultureInfo.GetCultures(CultureTypes.AllCultures & ~CultureTypes.NeutralCultures)
    .Where(x => x.ThreeLetterISOLanguageName == culture.ThreeLetterISOLanguageName && x.Name != culture.Name)
    .ToArray();

foreach (var c in sameLanguageCultures)
{
    Console.WriteLine(c.Name);
}

this will output

fr-FR
fr-BE 
fr-CA
fr-CH
fr-LU
fr-MC

Make it clear if am wrong.
