Timer in Portable Library

Question

I can\'t find a timer in portable library / Windows Store. (Targeting .net 4.5 and Windows Store aka Metro)

Does any have an idea on how to created some kind of timi

Answer 1

Following suggestion #3 from David Kean, here's my hacky Timer adapter - put this in a PCL library that targets .net 4.0, and reference it from 4.5:

    public class PCLTimer
    {
        private Timer _timer;

        private Action _action;

        public PCLTimer(Action action, TimeSpan dueTime, TimeSpan period)
        {
            _action = action;

            _timer = new Timer(PCLTimerCallback, null, dueTime, period);           
        }

        private void PCLTimerCallback(object state)
        {
            _action.Invoke();
        }

        public bool Change(TimeSpan dueTime, TimeSpan period)
        {
            return _timer.Change(dueTime, period);
        }
    }

And then to use it, you can do this from your 4.5 PCL library:

    private void TimeEvent()
    {            
        //place your timer callback code here
    }

    public void SetupTimer()
    {            
        //set up timer to run every second
        PCLTimer _pageTimer = new PCLTimer(new Action(TimeEvent), TimeSpan.FromMilliseconds(-1), TimeSpan.FromSeconds(1));

        //timer starts one second from now
        _pageTimer.Change(TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));

    }
