HumanLanguages 11.0.1

HumanLanguages

HumanLanguages is an open-source C# class library that provides a comprehensive database of human language names. It knows the name of every supported language in every supported language — 240 languages, fully cross-translated — plus locale/script variations and helpers for parsing ISO-style codes like en-US or da_DK.

Features

• Language names: the name of any language, written in any other language.
• Native names (endonyms): every language's own name for itself.
• Locale variations: per-language region and script variations (e.g. en-GB, sr-Cyrl) with native display names.
• Parsing: turn strings like "da-DK" or "da_DK" into strongly typed codes.
• No dependencies: plain data and enums, nothing else.

Getting Started

Install the NuGet package:

dotnet add package HumanLanguages

Usage

Parse a language code

using HumanLanguages;

var isoCode = HumanHelper.CreateLanguageIsoCode("da-DK"); // '-' and '_' both work, case-insensitive

Console.WriteLine(isoCode.LanguageId);                  // da
Console.WriteLine(isoCode.LanguageLocaleVariationCode); // DK
Console.WriteLine(isoCode.ToIsoCodeString());           // "da-DK"
Console.WriteLine(isoCode.ToIsoCodeString('_'));        // "da_DK"

Null, empty or unrecognized input falls back to English (en, Default).

Get a language's name in another language

var danish = Languages.LanguagePropertiesDictionary[LanguageId.da];

Console.WriteLine(danish.LanguageNames[LanguageId.en]); // "Danish"
Console.WriteLine(danish.LanguageNames[LanguageId.fr]); // "danois"
Console.WriteLine(danish.LanguageNames[LanguageId.ja]); // "デンマーク語"
Console.WriteLine(danish.LanguageNames[LanguageId.da]); // "dansk" (its own name)

List all languages with their native names

foreach (var languageId in Enum.GetValues<LanguageId>())
{
    var properties = Languages.LanguagePropertiesDictionary[languageId];
    Console.WriteLine($"{languageId}: {properties.LanguageNames[languageId]}");
}
// aa: Afar
// af: Afrikaans
// ...
// zu: isiZulu

Locale and script variations

var english = Languages.LanguagePropertiesDictionary[LanguageId.en];
Console.WriteLine(english.VariationNativeNames[LanguageLocaleVariationCode.GB]); // "United Kingdom"

var serbian = HumanHelper.CreateLanguageIsoCode("sr-Cyrl");
var serbianProperties = Languages.LanguagePropertiesDictionary[serbian.LanguageId];
Console.WriteLine(serbianProperties.VariationNativeNames[serbian.LanguageLocaleVariationCode]); // "ћирилица (Cyrillic)"
