Introduction
This class provides information about a specific culture, such as the names of the culture, the writing system, the calendar used, and how to format dates and sort strings. The information for this class is provided in the following table.
The CultureInfo class holds culture-specific information, such as the associated language, sublanguage, country/region, calendar, and cultural conventions. This class also provides access to culture-specific instances of DateTimeFormatInfo, NumberFormatInfo, CompareInfo, and TextInfo. These objects contain the information required for culture-specific operations, such as casing, formatting dates and numbers, and comparing strings. The String class indirectly uses this class to obtain information about the default culture.
Culture Names and Identifiers
The culture names follow the RFC 1766 standard in the format "<languagecode2>-<country/regioncode2>", where <languagecode2> is a lowercase two-letter code derived from ISO 639-1 and <country/regioncode2> is an uppercase two-letter code derived from ISO 3166. For example, U.S. English is "en-US". In cases where a two-letter language code is not available, the three-letter code derived from ISO 639-2 is used; for example, the three-letter code "div" is used for cultures that use the Dhivehi language. Some culture names have suffixes that specify the script; for example, "-Cyrl" specifies the Cyrillic script, "-Latn" specifies the Latin script. The following predefined culture names and identifiers are accepted and used by this and other classes in the System.Globalization namespace.
