Use Timer to update NotifyIcon

using System;

using System.Windows.Forms;
public class NotifyIconTimerUpdate : Form

    }
    private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)

        index++;
        if (index > 7) 
           index = 0;
    }
    [STAThread]

using System;

        images[7] = new Icon("3.ico");
    }
    private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
    {
        notifyIcon.Icon = images[index];
        index++;
        if (index > 7) 
           index = 0;
    }
    [STAThread]
