CultureInfo.TwoLetterISOLanguageName Property
Gets the ISO 639-1 two-letter code for the language of the current CultureInfo.
Assembly: mscorlib (in mscorlib.dll)

Type: System.StringThe ISO 639-1 two-letter code for the language of the current CultureInfo.
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.
The following example lists the cultures whose TwoLetterISOLanguageName property does not consist of a two-letter language code.
