[Edit]
If you want to translate a complete page, try this:
protected void Page_Load(object sender, EventArgs e)
{
string originalLanguage = "en";
string newLanguage = "nl";
string newLocation = String.Format("http://translate.google.com/translate?sl={0}&tl={1}&u={2}", originalLanguage, newLanguage, Request.Url.AbsoluteUri);
Response.Redirect(newLocation);
}
If you do this, you redirect your users to the Google Translate page that translates the content of your web page.
Hope this helps.
