Examples

using System;
using System.Globalization;
public class SamplesCultureInfo

    public static void Main()

        CultureInfo myCIintl = new CultureInfo("es-ES", false);
        // Creates and initializes the CultureInfo which uses the traditional sort.
        CultureInfo myCItrad = new CultureInfo(0x040A, false);
        // Displays the properties of each culture.

	Remarks
In most cases, the culture identifier is mapped to the corresponding NLS locale identifier.
In versions of Windows prior to Windows 10, the locale identifier LOCALE_CUSTOM_UNSPECIFIED (0x1000, or 4096) is assigned to custom cultures created by the user. Starting with Windows 10, it is assigned to any culture that does not have a unique locale identifier and does not have complete system-provided data. As a result, code that iterates cultures and retrieves those with an LCID value of LOCALE_CUSTOM_UNSPECIFIED returns a larger subset of CultureInfo objects if run under Windows 10.
Note
LCIDs are being deprecated, and implementers are strongly encouraged to use newer versions of APIs that support BCP 47 locale names instead. Each LCID can be represented by a BCP 47 locale name, but the reverse is not true. The LCID range is restricted and unable to uniquely identify all the possible combinations of language and region.
