獲取域名的詳細信息域名

當我搜索域名檢查的開放源代碼時，我得到了這個參考http://www.codeproject.com/KB/aspnet/DataScraping.aspx 其實它是在vb.net我轉換成C＃代碼並粘貼代碼在我的網頁我發送總源和代碼獲取域名的詳細信息域名

源代碼

雅是工作很好謝謝你非常Mr.Surajitkhamrai – 2009-11-04 08:28:35

嗨Mr.surjitkhamrai你r代碼工作正常，但它沒有得到域名的詳細信息，例如'.co'，'。in'域名是「對不起，這些信息目前不可用!!」。我需要域名信息，這是在.co，.in域名像'axisbank.co.in'它沒有提供的信息，請幫助我 – 2009-11-18 12:22:39
