ThreeLetterISOLanguageName Property

CultureInfo.ThreeLetterISOLanguageName Property

Gets the ISO 639-2 three-letter code for the language of the current CultureInfo.

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

abstract ThreeLetterISOLanguageName : string
override ThreeLetterISOLanguageName : string

Property Value

Type: System.String
The ISO 639-2 three-letter code for the language of the current CultureInfo.

For example, the three-letter abbreviation for English is "eng".


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.

The following code example displays several properties of the neutral cultures.


The example displays the older "zh-CHS" and "zh-CHT" culture names with the 0x0004 and 0x7C04 culture identifiers, respectively. However, your Windows Vista applications should use the zh-Hans name instead of "zh-CHS" and the zh-Hant name instead of "zh-CHT". The zh-Hans and zh-Hant names represent the current standard, and should be used unless you have a reason for using the older names.

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