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

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. |
If ISO 639-1 does not define a two-letter language code for a particular culture, the TwoLetterISOLanguageName property returns a string that consists of three or more letters. For more information, see the example.
The following example lists the cultures whose TwoLetterISOLanguageName property does not consist of a two-letter language code.
using System; using System.Globalization; public class Example { public static void Main() { // Get all available cultures on the current system. CultureInfo[] cultures = CultureInfo.GetCultures(CultureTypes.AllCultures); Console.WriteLine("{0,-32} {1,-13} {2,-6}\n", "Display Name", "Name", "TwoLetterISOLanguageName"); foreach (var culture in cultures) { // Exclude custom cultures. if ((culture.CultureTypes & CultureTypes.UserCustomCulture) == CultureTypes.UserCustomCulture) continue; // Exclude all two-letter codes. if (culture.TwoLetterISOLanguageName.Length == 2) continue; Console.WriteLine("{0,-32} {1,-13} {2,-6}", culture.DisplayName, culture.Name, culture.TwoLetterISOLanguageName); } } } // The example output like the following: // Display Name Name TwoLetterISOLanguageName // // Upper Sorbian hsb hsb // Konkani kok kok // Syriac syr syr // Tamazight tzm tzm // Filipino fil fil // Quechua quz quz // Sesotho sa Leboa nso nso // Mapudungun arn arn // Mohawk moh moh // Alsatian gsw gsw // Sakha sah sah // K'iche qut qut // Dari prs prs // Upper Sorbian (Germany) hsb-DE hsb // Konkani (India) kok-IN kok // Syriac (Syria) syr-SY syr // Filipino (Philippines) fil-PH fil // Quechua (Bolivia) quz-BO quz // Sesotho sa Leboa (South Africa) nso-ZA nso // Mapudungun (Chile) arn-CL arn // Mohawk (Mohawk) moh-CA moh // Alsatian (France) gsw-FR gsw // Sakha (Russia) sah-RU sah // K'iche (Guatemala) qut-GT qut // Dari (Afghanistan) prs-AF prs // Lower Sorbian (Germany) dsb-DE dsb // Tamazight (Latin, Algeria) tzm-Latn-DZ tzm // Quechua (Ecuador) quz-EC quz // Quechua (Peru) quz-PE quz // Sami, Lule (Norway) smj-NO smj // Sami, Lule (Sweden) smj-SE smj // Sami, Southern (Norway) sma-NO sma // Sami, Southern (Sweden) sma-SE sma // Sami, Skolt (Finland) sms-FI sms // Sami, Inari (Finland) smn-FI smn // Sami (Inari) smn smn // Sami (Skolt) sms sms // Sami (Southern) sma sma // Lower Sorbian dsb dsb // Sami (Lule) smj smj // Tamazight (Latin) tzm-Latn tzm
