I have a windows service application. I want this windows service to run a method after every x minutes. I also want when the existing method is running, it should not allow the timer method to execute. I have,
private static readonly ILogger Logger = GetLogger();
private Timer _timer;
protected override void OnStart(string[] args)
{
Logger.Log("Starting Timer");
StartTimer();
}
protected override void OnStop()
{
Logger.Log("Stoping Timer");
StopTimer();
}
private void Timer_Elapsed(object state)
{
Logger.Log("Timer Elapsed");
DoWork();
RestartTimer();
}
private static void DoWork()
{
try
{
// Doing my work there
}
catch (Exception ex)
{
Logger.Log(ex);
}
}
private void StartTimer()
{
Logger.Log("Running first time manually");
ThreadPool.QueueUserWorkItem((_) => DoWork());
var frequency = GetTimerFrequency();
_timer = new Timer(Timer_Elapsed, null, frequency, Timeout.Infinite);
}
private void RestartTimer()
{
var frequency = GetTimerFrequency();
_timer.Change(frequency, Timeout.Infinite);
}
private void StopTimer()
{
_timer.Change(Timeout.Infinite, Timeout.Infinite);
_timer.Dispose();
_timer = null;
}
I dunno why but some-times when the method DoWork is running, Timer_Elapsed is executing. I want until one DoWork finished, no more DoWork is allowed to execute.
