Parsing three-letter language names as culture info

Question

I'm working with an API that returns some information about audio streams in a file, more specifically the audio language in its three-letter ISO name (ISO 639-2) representation.

I would like to parse this information into a new CultureInfo object, but there is no constructor that takes a three-letter code. I could of course write an enormous select statement (switch for you C# people), but I figured it would be more cost-efficient to ask around for a better way first. So am I out of luck or is there a secret way to create a CultureInfo object using three letter names?

Answer 1

EDIT: sorry, I've used the wrong property:

public static CultureInfo FromISOName(string name)
{
    return CultureInfo
        .GetCultures(CultureTypes.NeutralCultures)
        .FirstOrDefault(c => c.ThreeLetterISOLanguageName == name);
}

However, there are still duplicates in the list and no support for "dut".

Answer 2

I would go for Balazs solution, but it would be better in your case to use CultureTypes.NeutralCultures as you don't seem to be concerned with region/country data.

It would always return a single CultureInfo with no need of FirstOrDefault
