# Google Language Translator in C#

## Google Language Translator in C#

In this article, I am trying to explain the concept of how to use Google Language Translator in C#? Here I am using Asynchronous Google Translator and create the WebClient instance.

##### Getting started: -

**(1).** Create a console application and give the appropriate name.

**(2).** Create a class for mapping the Language

```
public static void LanguageMap(Dictionary<string, string> language)
{
       language.Add("Afrikaans", "af");
       language.Add("Albanian", "sq");
       language.Add("Arabic", "ar");
       language.Add("Armenian", "hy");
       language.Add("Azerbaijani", "az");
       language.Add("Basque", "eu");
       language.Add("Belarusian", "be");
       language.Add("Bengali", "bn");
       language.Add("Bulgarian", "bg");
       language.Add("Catalan", "ca");
       language.Add("Chinese", "zh-CN");
       language.Add("Croatian", "hr");
       language.Add("Czech", "cs");
       language.Add("Danish", "da");
       language.Add("Dutch", "nl");
       language.Add("English", "en");
 }
```

Get all Languages then follow this link [http://msdn.microsoft.com/en-us/goglobal/bb896001.aspx](http://msdn.microsoft.com/en-us/goglobal/bb896001.aspx)

**(3).** In the Main method write the below line of code.

```
static void Main(string[] args)
{
    try
    {
        string fromLanguage, toLanguage, text; // create string type of variable
        text = "hello"; // give the text for converting other language
        fromLanguage = "English"; // form language means source language
        toLanguage = "Danish"; // to language for converting in this language
        var language = new Dictionary<string, string>(); // create a Dictionary type  variable
        Language.LanguageMap(language); // Call the LanuageMap method for initiate the language.
        Console.WriteLine("Your Text: " + text); // show your raw text on the screen
        Uri address = new Uri("http://translate.google.com/translate_t"); // create a uri type address named variable and uriString means pass the URL.
        WebClient webClient = new WebClient();// create the WebClient instance
        webClient.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded"; // Give the Content type for WebClents Headers
        webClient.UploadStringCompleted += new UploadStringCompletedEventHandler(webClient_UploadStringCompleted); // overload the UploadStringComplete event.
        webClient.UploadStringAsync(address, GetPostData(language[fromLanguage], language[toLanguage], text)); // this method is uploads the specified string to the specified resorce.
        Console.ReadKey();
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex);
        Console.ReadKey();
    }
}
```

Note: - The content-type "application/x-www-form-URL-encoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content-type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.

**(4).** Create a method with GetPostData() name which takes three parameters with from language, language and text and it will put the language translation for from and to and also encode the content.

```
static string GetPostData(string fromLanguage, string toLanguage, string text)
{
     string data = string.Format("hl=en&ie=UTF8&oe=UTF8submit=Translate&langpair={0}|{1}", fromLanguage, toLanguage); // Here put the language translation for from and to.
     return data += "&text=" + HttpUtility.UrlEncode(text); // Here Encoded the content.
}
```

**(5).** In the last handle the UploadStringComplete event with a method which name is webClient_UploadStringCompleted

```
static void webClient_UploadStringCompleted(object sender, UploadStringCompletedEventArgs e)
{
  if (e.Result != null) // Check the event result is null or not.
  {
    var document =new HtmlDocument();// create new HtmlDocument to store my page html.
    document.LoadHtml(e.Result); // Now load the getting Html
    var node = document.DocumentNode.SelectSingleNode("//span[@id='result_box']"); // Here finding particular tag to get value from HtmlDocument
    var output = node != null ? node.InnerText : e.Error.Message;
    Console.WriteLine("Translated Text: " + output); // show the output
  }
}
```

                toLanguage = "Danish";
                var language = new Dictionary<string, string>();
                Language.LanguageMap(language);
                Console.WriteLine("Your Text: " + text);
                Uri address = new Uri("http://translate.google.com/translate_t");
                WebClient webClient = new WebClient();
                webClient.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
                webClient.UploadStringCompleted += new UploadStringCompletedEventHandler(webClient_UploadStringCompleted);

            {
                Console.WriteLine(ex);
                Console.ReadKey();
            }
        }
        static string GetPostData(string fromLanguage, string toLanguage, string text)
        {
            string data = string.Format("hl=en&ie=UTF8&oe=UTF8submit=Translate&langpair={0}|{1}", fromLanguage, toLanguage);
            return data += "&text=" + HttpUtility.UrlEncode(text);
        }

        {
            if (e.Result != null)
            {
                var document = new HtmlDocument(); // Here creating new html document to store my page html
                document.LoadHtml(e.Result); // now load getting html
                var node = document.DocumentNode.SelectSingleNode("//span[@id='result_box']"); // finding particular tag to get value from html document
                var output = node != null ? node.InnerText : e.Error.Message;
                Console.WriteLine("Translated Text: " + output); // show the output
            }
        }
    }
    public class Language
    {
        public static void LanguageMap(Dictionary<string, string> language)
        {
            language.Add("Afrikaans", "af");
            language.Add("Albanian", "sq");
            language.Add("Arabic", "ar");
            language.Add("Armenian", "hy");
