Property Value


A string that is the RFC 4646 standard identification for a language.




This property and the GetCultureInfoByIetfLanguageTag method are deprecated. Instead, you should use a the CultureInfo.Name property. IETF tags and names are identical.

The RFC 4646 standard that is maintained by the Internet Engineering Task Force (IETF) defines an IETF language tag, which provides a uniform means of identifying a language. The format of an IETF language tag is similar to the culture name returned by the Name property, but does not identify a culture uniquely. That is, different cultures share the same IETF language tag if those cultures have identical linguistic characteristics. The linguistic characteristics of a culture are contained in the TextInfo object associated with a CultureInfo object.

An IETF language tag consists of a mandatory language identifier, an optional script identifier, and an optional region identifier.

For more information, see RFC 5646, "Tags for Identifying Languages. For a list of subtags, see The IANA Language Subtag Registry.
