ThreeLetterWindowsLanguageName Property

CultureInfo.ThreeLetterWindowsLanguageName Property


Gets the three-letter code for the language as defined in the Windows API.

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

public virtual string ThreeLetterWindowsLanguageName { get; }

Property Value

Type: System.String

The three-letter code for the language as defined in the Windows API.

This property returns the same value as the Windows API method GetLocaleInfo with the LOCALE_SABBREVLANGNAME value. For example, the three-letter code for English (United States) as defined in the Windows API is "enu".


When communicating between processes or persisting data it is usually better to use the full CultureInfo.Name. Using just the language can lose context and data.

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


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.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);
