* E2 y4 V+ M+ e) OHere is how you can translate a Text using Google's "Unofficial" API's.
) D/ B- M+ h; ^' D( mThe 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.
' C% D( D! @0 }4 ABelow is a C# function which translates, scrapes and gives you the result. I am using String.Substring function but you can use Regex too.
