CultureInfo Constructor

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Updated: June 2010

Initializes a new instance of the CultureInfo class based on the culture specified by name.

Namespace:  System.Globalization
Assembly:  mscorlib (in mscorlib.dll)


Public Sub New ( _
    name As String _
public CultureInfo(
    string name



Exception Condition

name is null.


On Windows systems, name is not a valid culture name.


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.

If name is not a valid culture name, the behavior of this constructor differs by platform. On Windows systems, it throws an CultureNotFoundException. On Macintosh systems, it returns a CultureInfo object that represents the system's default culture.

If name is the name of the current system culture, the CultureInfo object instantiated by this method reflects any customizations that the user may have made to the system's culture information. 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 user settings are incompatible with the culture associated with the CultureInfo object (for example, if the selected calendar is not a member of the current culture's OptionalCalendars array), 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 information for the specified culture that is supplied by the operating system.

Older operating system versions do not always recognize the euro as a particular culture's default currency. In this case, the .NET Framework for Silverlight will reflect this inaccuracy because it is dependent on the operating system for its currency information,
