域名檢查器（Whois）？

。我用c＃語言開發了一個使用asp.net的網頁，在這個網頁中，我有一個用於獲取域和按鈕的url的文本框。當用戶在文本框中輸入域名並按下按鈕時，該域的詳細信息將顯示在另一個窗口中。我從stackoverflow用戶獲得幫助，我得到的代碼工作正常，但是當我輸入域名特別是「.in」時，doamins沒有提供詳細信息。只是域可用消息顯示實際上該域名已註冊例如我嘗試「axisbank.co.in」在我的網頁它顯示的域是可用的，但實際上它已被採取。我送我的代碼，請幫我（特別。在域名）域名檢查器（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 !! "; 
    } 

}
