Remarks
For example, the two-letter abbreviation for English is "en". The TwoLetterISOLanguageName property value for the invariant culture is "iv".
Note
When communicating between processes or persisting data it is usually better to use the full CultureInfo.Name. Using just the language can lose context and data.
If ISO 639-1 does not define a two-letter language code for a particular culture, the TwoLetterISOLanguageName property returns a string that consists of three or more letters. For more information, see the example.
