 //显示楼主地理位置 
SqlDataReader Rg = DataHelper.ExecuteReader("SELECT [srcip],[tkg] FROM [wap_online] WHERE [uid]=" + tuid + "");
 while (Rg.Read())
    {
        int tkg = Convert.ToInt32(Rg[1]);
        string woip = Rg[0].ToString();
          if (tkg == 1)
        {
            TextString += "<iframe width=\"250\" height=\"27\" frameborder=\"0\" scrolling=\"no\" src=\"https://up.pcno.cn/m/ip/?ip="+ woip +"\"></iframe>\r\n";
        }
        else
        {
            TextString += "<img src=\"/image/site/map.png\" height=\"18\" alt=\"ip\"/>楼主关闭了地理位置，隐私保护中！<br/>\r\n";
}
