CultureInfo::TwoLetterISOLanguageName Property


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Gets the ISO 639-1 two-letter code for the language of the current CultureInfo.

Namespace:   System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

property String^ TwoLetterISOLanguageName {
	virtual String^ get();

Property Value

Type: System::String^

The 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".


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.

No code example is currently available or this language may not be supported.
