        string domain = Request["domain"].Trim();        string[] domainarry = domain.Split(".");
        string tar = "http://panda.www.net.cn/cgi-bin/Whois.cgi?domain=" + Server.UrlEncode(domainarry[0]) + "&referer=http://www.net.cn/static/domain/&"
        string domtemp = domain.Replace(domainarry[0],"");
        domtemp = domtemp.Replace(".中国",".cn");
        domtemp=domtemp.Replace(".网络",".net.cn");
        domtemp=domtemp.Replace(".公司",".com.cn");        string xend = domtemp.Replace(".","")&"=yes";
        tar=tar&xend;        string retdns=P_GETx(tar,"http://www.net.cn/static/domain/");
public string P_GETx(string tar , string url)
    {
        string returnstr;
        try 
    {         
    WebRequest request = WebRequest.Create(url);
            request.Timeout=20000;
            WebResponse response = request.GetResponse();
            Stream resStream = response.GetResponseStream();
            StreamReader sr = new StreamReader(resStream, System.Text.Encoding.Default);
            returnstr=sr.ReadToEnd();
            resStream.Close();
            response.Close();
            request.Abort();
            sr.Close();
    }
    catch (WebException ex)
        {
            if (ex.Status == WebExceptionStatus.ConnectFailure)
            {
                //无法连接到远程服务器, --换代理 IP 
                //MessageBox.Show(ex.ToString()); 
                //初始化代理  IP 
                returnstr="无法连接到远程服务器";
            }
            else if (ex.Status == WebExceptionStatus.Timeout)
            {
                //超时 --换代理 IP 
                //MessageBox.Show(ex.ToString()); 
                returnstr="超时";
            }
            else if (ex.Status == WebExceptionStatus.ProtocolError)
            {
                //文件未找到--跳出 
                //MessageBox.Show(ex.ToString()); 
                returnstr="文件未找到";
            }
        }
    }这样是否可行?
高手指点一下.
