根据外网IP获取地址

须下载QQip数据库“QQWry.Dat” 调用方式如下： //string ipfilePath = @"C:\Program Files\Tencent\QQ\Bin\QQWry.Dat"; //IPSearch ipSearch = new IPSearch(ipfilePath); //string ip = CommHelper.GetWebIp();//"72.51.27.51"; //IPSearch.IPLocation loc = ipSearch.GetIPLocation(ip); //Console.WriteLine("你查的ip是：{0} 地理位置：{1} {2}", ip, loc.country, loc.area);
