C#向IIS的黑名单写IP

通过前台WEB记录IP访问情况，后台服务定时作规则统计，写黑名单写入IIS的拒绝访问列表里，很有意义噢

static void Main(string[] args)
        {
            try

                // retrieve the list of currently denied IPs
                Console.WriteLine("Retrieving the list of currently denied IPs.");
                // get the IPSecurity property
