Here is how you can translate a Text using Google's "Unofficial" API's.
) _; C7 k4 c7 qThe URL for Google Translate is - http://www.google.com/translate_ ... =UTF8&text={0}&langpair={1}

[li]"text" is your input string which needs to be translated. [/li][li]langpair is the language pairs involved in the tranlsation. E.g. "ar|en" means translate from Arabic to English.[/li]

The result when you browse to the URL is a HTML page. You will have to do screen scraping to get your translated text.
' o; L! h- [3 \/ o8 g) }1 G4 CBelow is a C# function which translates, scrapes and gives you the result. I am using String.Substring function but you can use Regex too.
