关于使用Timer定时监测网络是否ping通

 void timer_Tick(object sender, EventArgs e)
        {
            Ping pingSender = new Ping();
            PingReply reply = pingSender.Send("192.168.1.104", 1000);
            if (reply.Status != IPStatus.Success)
            {
                Message.show("网络异常")
            }
        }

 void pingSender_PingCompleted(object sender, PingCompletedEventArgs e)
        {
            (sender as IDisposable).Dispose();
        }
