Hi friend, first get the page source like WebRequest Request = WebRequest.Create("URL"); WebResponse Response = Request.GetResponse(); Stream RStream = Response.GetResponseStream(); Encoding en = System.Text.Encoding.GetEncoding("utf-8"); StreamReader read = new StreamReader( RStream, en ); string str=read.ReadToEnd(); and made searches in the str(source page) and display on default page
