Declaration
public CultureInfo Culture { get; set; }
Property Value
System.Globalization.CultureInfo

Remarks

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 CultureInfo names and identifiers are accepted and used by this class and other classes in the System.Globalization namespace.
