Using Google Translate in C# [closed]

Question

I have to translate some text with Google's translate service. All code I've found doesn't work. I think because they have changed their service. If someone has working code, I would be very glad.

Answer 2

The reason the first code sample doesn't work is because the layout of the page changed. As per the warning on that page: "The translated string is fetched by the RegEx close to the bottom. This could of course change, and you have to keep it up to date." I think this should work for now, at least until they change the page again.

public string TranslateText(string input, string languagePair)
{
    string url = String.Format("http://www.google.com/translate_t?hl=en&ie=UTF8&text={0}&langpair={1}", input, languagePair);
    WebClient webClient = new WebClient();
    webClient.Encoding = System.Text.Encoding.UTF8;
    string result = webClient.DownloadString(url);
    result = result.Substring(result.IndexOf("<span title=\"") + "<span title=\"".Length);
    result = result.Substring(result.IndexOf(">") + 1);
    result = result.Substring(0, result.IndexOf("</span>"));
    return result.Trim();
}

Google Translate Kit, an open source library http://ggltranslate.codeplex.com/

Translator gt = new Translator();
/*using cache*/
DemoWriter dw = new DemoWriter();
gt.KeyGen = new SimpleKeyGen();
gt.CacheManager = new SimleCacheManager();
gt.Writer = dw;
Translator.TranslatedPost post = gt.GetTranslatedPost("Hello world", LanguageConst.ENGLISH, LanguageConst.CHINESE);
Translator.TranslatedPost post2 = gt.GetTranslatedPost("I'm Jeff", LanguageConst.ENGLISH, LanguageConst.CHINESE);
this.result.InnerHtml = "<p>" + post.text +post2.text+ "</p>";
dw.WriteToFile();

I found this code works for me:

public String Translate(String word)
{
    var toLanguage = "en";//English
    var fromLanguage = "de";//Deutsch
    var url = $"https://translate.googleapis.com/translate_a/single?client=gtx&sl={fromLanguage}&tl={toLanguage}&dt=t&q={HttpUtility.UrlEncode(word)}";
    var webClient = new WebClient
    {
        Encoding = System.Text.Encoding.UTF8
    };
    var result = webClient.DownloadString(url);
    try
    {
        result = result.Substring(4, result.IndexOf("\"", 4, StringComparison.Ordinal) - 4);
        return result;
    }
    catch
    {
        return "Error";
    }
}

Answer 5

When I used above code.It show me translated text as question mark like (???????).Then I convert from WebClient to HttpClient then I got a accurate result.So you can used code like this.

public static string TranslateText( string input, string languagePair)       
{
    string url = String.Format("http://www.google.com/translate_t?hl=en&ie=UTF8&text={0}&langpair={1}", input, languagePair);
    HttpClient httpClient = new HttpClient();
    string result = httpClient.GetStringAsync(url).Result;
    result = result.Substring(result.IndexOf("<span title=\"") + "<span title=\"".Length);
    result = result.Substring(result.IndexOf(">") + 1);
    result = result.Substring(0, result.IndexOf("</span>"));
    return result.Trim();
}

Then you Call a function like.You put first two letter of any language pair.

From English(en) To Urdu(ur).

TranslateText(line, "en|ur")

Answer 6

Here is my slighly different code, solving also the encoding issue:

public string TranslateText(string input, string languagePair)
{
    string url = String.Format("http://www.google.com/translate_t?hl=en&ie=UTF8&text={0}&langpair={1}", input, languagePair);
    WebClient webClient = new WebClient();
    webClient.Encoding = System.Text.Encoding.Default;
    string result = webClient.DownloadString(url);
    result = result.Substring(result.IndexOf("TRANSLATED_TEXT"));
    result = result.Substring(result.IndexOf("'")+1);
    result = result.Substring(0, result.IndexOf("'"));
    return result;
}

Example of the function call:

var input_language = "en";
var output_language = "es";
var result = TranslateText("Hello", input_language + "|" + output_language);

The result will be "Hola"

Answer 7

Google is going to shut the translate API down by the end of 2011, so you should be looking at the alternatives!
