$ {( Z9 f8 o) j  f
: O' Z$ k/ s2 R- u" lHere is how you can translate a Text using Google's "Unofficial" API's.
/ g$ i/ p  p0 J) m0 _. TThe URL for Google Translate is - http://www.google.com/translate_ ... =UTF8&text={0}&langpair={1}
* G" }  ^# X" j# [

[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.
Below is a C# function which translates, scrapes and gives you the result. I am using String.Substring function but you can use Regex too.
