Reset System.Timers.Timer to prevent an expired event

I am trying to use Timerevents to trigger data transmission over a network. I created a simple class for debugging. Mostly I have List<string>one that I would like to send. I want the following:

  • Add row to List
  • Run Timerin 10 seconds
  • Add a second line ListtoTimer.Elapsed
  • Restart Timerback for 10 seconds.

So far I have this:

public static List<string> list;
public static Timer timer;
public static bool isWiredUp = false;

public static void Log(string value) {
    if (list == null) list = new List<string>();
    list.Add(value);

    //this does not reset the timer, elapsed still happens 10s after #1
    if (timer != null) {
        timer = null;
    }

    timer = new Timer(10000);
    timer.Start();
    timer.Enabled = true;
    timer.AutoReset = false;

    if (!isWiredUp) {
        timer.Elapsed += new ElapsedEventHandler(SendToServer);
        isWiredUp = true;
    }
}

static void SendToServer(object sender, ElapsedEventArgs e) {
    timer.Enabled = false;
    timer.Stop();
}

Any ideas?
