域名检查器（Whois）？

。我用c＃语言开发了一个使用asp.net的网页，在这个网页中，我有一个用于获取域和按钮的url的文本框。当用户在文本框中输入域名并按下按钮时，该域的详细信息将显示在另一个窗口中。我从stackoverflow用户获得帮助，我得到的代码工作正常，但是当我输入域名特别是“.in”时，doamins没有提供详细信息。只是域可用消息显示实际上该域名已注册例如我尝试“axisbank.co.in”在我的网页它显示的域是可用的，但实际上它已被采取。我送我的代码，请帮我（特别。在域名）域名检查器（Whois）？

protected void Button1_Click(object sender, EventArgs e) 
{ 
    lblDomainName.Text = Session["WhoIs"].ToString(); 
    string firstLevelbufData = null; 
    // Stores the bufData extracted from the webclient 
    try 
    { 
     // similarly we can select any server address for bufData mining 
     string strURL = "http://www.directnic.com/whois/index.php?query=" + txtDomain.Text; 
     WebClient web = new WebClient(); 
     // byte array to store the extracted bufData by 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) 
    { 
     // this exception will be fired when the host name is not resolved or any other connection problem 
     //txtResult.Text = ex.Message.ToString();//sasi 
     lblresult.Text = ex.Message.ToString(); 
     return; 
    } 
    try 
    { 
     // first and last are the regular expression string for extraction bufData witnin two tags 
     // you can change according to your requirement 
     string first = null; 
     string last = null; 
     // chr(34) is used for (") symbol 
     first = "<p class=\"text12\">"; 
     last = "</p>"; 

     Regex RE = new Regex(first + "(?<MYDATA>.*?(?=" + last + "))", RegexOptions.IgnoreCase | RegexOptions.Singleline); 
     // try to extract the bufData within the first and last tag 
     Match m = RE.Match(firstLevelbufData); 
     // got the result 
     //txtResult.Text = m.Groups["MYDATA"].Value + "<br>";//sasi 
     lblresult.Text = m.Groups["MYDATA"].Value + "<br>"; 
     // check if no information abour that domain is available 
     //if (txtResult.Text.Length < 10) txtResult.Text = "Domain "+ txtDomain .Text +" is Available";//sasi 
     if (lblresult.Text.Length < 10) 

      lblresult.Text = "Domain " + txtDomain.Text + " is Available"; 
    } 
    catch (System.Net.WebException ex) 
    { 
     lblresult.Text = " Sorry the information is currently not available !! "; 
    } 

}
