How to check if culture exists in .NET

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);
}
