Language to = GoogleTranslator.GetLanguageByName("Japanese");

TranslationResult result = await translator.TranslateLiteAsync("Hello. How are you?", from, to);

//The result is separated by the suggestions and the '\n' symbols
string[] resultSeparated = result.FragmentedTranslation;

//You can get all text using MergedTranslation property
string resultMerged = result.MergedTranslation;

//There is also original text transcription
string transcription = result.TranslatedTextTranscription; // Kon'nichiwa! Ogenkidesuka?

var result2 = await translator.TranslateLiteAsync("Drones", Language.Auto, Language.Czech);

foreach(LanguageDetection languageDetection in result2.LanguageDetections)
{

// Spanish (0.61010)
// English (0.34365)

Language spanish = new Language("Spanish", "es"); // For the method, only the second parameter is important (ISO639)

result2 = await translator.TranslateLiteAsync("world", spanish, Language.Czech);
Console.WriteLine(result2.LanguageDetections.First()); // English (0.98828)
Console.WriteLine(result2.MergedTranslation) // мир

var result3 = await translator.TranslateLiteAsync(misspellingsText, english, GoogleTranslator.GetLanguageByISO("ru"));

if(result3.Corrections.TextWasCorrected)
	Console.WriteLine(string.Join(",", result3.Corrections.CorrectedWords); // "quick", "over"
	
Console.WriteLine(result3.MergedTranslation) // "Быстрая коричневая лиса прыгает через ленивую собаку"

GoogleTranslator translator = new GoogleTranslator();
