In .NET Compact Framework applications, culture is not supported by the operating system of the device.

For a list of predefined culture names, see the National Language Support (NLS) API Reference at the Go Global Developer Center.

If name is String.Empty, the constructor creates an instance of the invariant culture; this is equivalent to retrieving the value of the InvariantCulture property.

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 culture identifier associated with name matches the culture identifier of the current Windows culture, this constructor creates a CultureInfo object 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 object, 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 culture identifier associated with the specified culture name does not match the culture identifier of the current Windows culture, this constructor creates a CultureInfo object 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 culture of Windows and the user changed the calendar from Hijri to Gregorian.

The LCID property of the new CultureInfo is set to the culture identifier associated with the specified name.

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 do this. 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.
