Question

I have this code, when I try to get not existed culture I get exception.
Is there exists method like TryGetCultureInfo, which return bool value? I don’t want to use try-catch statement

CultureInfo culture = CultureInfo.GetCultureInfo(cultureCode);
if (culture == null)
{
    culture = CultureInfo.GetCultureInfo(DefaultCultureCode);
}

I think there’s no such method. So you could just try-catch or check all installed cultures:

string cultureCode = "de-DE";
CultureInfo[] cultures = CultureInfo.GetCultures(CultureTypes.AllCultures & ~CultureTypes.NeutralCultures);
var culture = cultures.FirstOrDefault(c => c.Name.Equals(cultureCode, StringComparison.OrdinalIgnoreCase));
if (culture == null)
{
    culture = cultures.FirstOrDefault(c => c.Name.Equals(DefaultCultureCode, StringComparison.OrdinalIgnoreCase));
    if (culture == null)
        culture = CultureInfo.CurrentCulture;
}

But i would prefer the try-catch, i’m sure it is more efficient.

public bool TryGetCultureInfo(string cultureCode, string DefaultCultureCode, out CultureInfo culture)
{
    try
    {
        culture = CultureInfo.GetCultureInfo(cultureCode);
        return true;
    } catch(CultureNotFoundException)
    {
        if (DefaultCultureCode == null)
            culture = CultureInfo.CurrentCulture;
        else
        {
            try
            {
                culture = CultureInfo.GetCultureInfo(DefaultCultureCode);
            } catch (CultureNotFoundException)
            {
                culture = CultureInfo.CurrentCulture;
            }
        }
    }
    return false;
}
