CultureInfo Constructor (Int32)
Initializes a new instance of the CultureInfo class based on the culture specified by the culture identifier.
Assembly: mscorlib (in mscorlib.dll)
Predefined culture identifiers are listed in the National Language Support (NLS) API Reference at the Go Global Developer Center.
In most cases, the culture parameter is mapped to the corresponding National Language Support (NLS) locale identifier. The value of the culture parameter becomes the value of the LCID property of the new CultureInfo.
We recommend that you call the locale name constructor CultureInfo.CultureInfo, because locale names are preferable to LCIDs. For custom locales, a locale name is required.
The user might choose to override some of the values associated with the current culture of Windows through the regional and language options portion of Control Panel. For example, the user might choose to display the date in a different format or to use a currency other than the default for the culture. If the specified culture identifier matches the culture identifier of the current Windows culture, this constructor creates a CultureInfo that uses those overrides, including user settings for the properties of the DateTimeFormatInfo instance returned by the DateTimeFormat property, and the properties of the NumberFormatInfo instance returned by the NumberFormat property. If the user settings are incompatible with the culture associated with the CultureInfo (for example, if the selected calendar is not one of the OptionalCalendars) the results of the methods and the values of the properties are undefined.
If the specified culture identifier does not match the identifier of the current Windows culture, this constructor creates a CultureInfo that uses the default values for the specified culture.
The UseUserOverride property is always set to true.
For example, suppose that Arabic (Saudi Arabia) is the current Windows culture and the user has changed the calendar from Hijri to Gregorian.
For cultures that use the euro, the .NET Framework and Windows XP set the default currency as euro. However, older versions of Windows do not. Therefore, if the user of an older version of Windows has not changed the currency setting through the regional and language options portion of Control Panel, the currency might be incorrect. To use the .NET Framework default setting for the currency, the application should use a CultureInfo constructor overload that accepts a useUserOverride parameter and set it to false.
For backwards compatibility, a culture constructed using a culture parameter of 0x0004 or 0x7c04 will have a Name property of zh-CHS or zh-CHT, respectively. You should instead prefer to construct the culture using the current standard culture names of zh-Hans or zh-Hant, unless you have a reason for using the older names.
Notes to Callers:
The .NET Framework 3.5 and earlier versions throw an ArgumentException if culture is not a valid culture identifier. Starting with the .NET Framework 4, this constructor throws a CultureNotFoundException. Starting with apps that run under the .NET Framework 4 or later on Windows 7 or later, the method attempts to retrieve a CultureInfo object whose identifier is culture from the operating system; if the operating system does not support that culture, the method throws a CultureNotFoundException exception.
