CultureInfo.TwoLetterISOLanguageName Property

Gets the ISO 639-1 two-letter code for the language of the current CultureInfo.

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

public virtual string TwoLetterISOLanguageName { get; }

Property Value

Type: System.String
The ISO 639-1 two-letter code for the language of the current CultureInfo.

For example, the two-letter abbreviation for English is "en".

The following code example displays several properties of the neutral cultures.

NoteNote:

The example displays the older "zh-CHS" and "zh-CHT" culture names with the 0x0004 and 0x7C04 culture identifiers, respectively. However, your Windows Vista applications should use the zh-Hans name instead of "zh-CHS" and the zh-Hant name instead of "zh-CHT". The zh-Hans and zh-Hant names represent the current standard, and should be used unless you have a reason for using the older names.

using System;
using System.Globalization;

public class SamplesCultureInfo  {

   public static void Main()  {

      // Displays several properties of the neutral cultures.
      Console.WriteLine( "CULTURE ISO ISO WIN DISPLAYNAME                              ENGLISHNAME" );
      foreach ( CultureInfo ci in CultureInfo.GetCultures( CultureTypes.NeutralCultures ) )  {
         Console.Write( "{0,-7}", ci.Name );
         Console.Write( " {0,-3}", ci.TwoLetterISOLanguageName );
         Console.Write( " {0,-3}", ci.ThreeLetterISOLanguageName );
         Console.Write( " {0,-3}", ci.ThreeLetterWindowsLanguageName );
         Console.Write( " {0,-40}", ci.DisplayName );
         Console.WriteLine( " {0,-40}", ci.EnglishName );
      }

   }
