        string strURL = "http://www.directnic.com/whois/index.php?query=" + txtDomain.Text;
        WebClient web = new WebClient();
        // byte array to store the extracted bufData by开发者_JS百科 webclient
        byte[] bufData = null;
        bufData = web.DownloadData(strURL);
        // got the bufData now convert it into string form
        firstLevelbufData = Encoding.Default.GetString(bufData);
    }
    catch (System.Net.WebException ex)

        //txtResult.Text = m.Groups["MYDATA"].Value + "<br>";//sasi
        lblresult.Text = m.Groups["MYDATA"].Value + "<br>";
