无法触发事件（计时器）

Question

I have a function in winform that is executed every x time (eg. every 60 minutes).
And then it does some stuff, then I want it to wait some seconds (using a timer) and then execute do some stuff part2.

 private void goToFtp(int time)
        { 
            double interval = time* 60 * 1000;
            System.Timers.Timer checkForTime = new System.Timers.Timer(interval);
            checkForTime.Elapsed += new ElapsedEventHandler(checkForTime_Elapsed);
            checkForTime.Enabled = true;
        }



    System.Windows.Forms.Timer timerDelayWatcher = new System.Windows.Forms.Timer();

    private void checkForTime_Elapsed(object sender, ElapsedEventArgs e)
        {

         .......Do some stuff part1

            timerDelayWatcher.Tick += new EventHandler(timerDelayWatcher_Tick); // Everytime timer ticks, timer_Tick will be called
            timerDelayWatcher.Interval = (1000) * (5);              
            timerDelayWatcher.Enabled = true;                       
            timerDelayWatcher.Start();
        }


            private void timerDelayWatcher_Tick(object sender, EventArgs e)
        {

            timerDelayWatcher.Stop();

                .......Do some stuff part2

        }

The problem is that the timerDelayWatcher_Tick is not fired...any ideias why?

Answer 1

Try calling the start method on the system.timers.timer firstly, and I would recommend sticking to one type of timer, and pattern of use, say use the system.timer.timer and do the work you need on elapsed, then restart with and wait for the next elapsed event.

Either that or I would suggest looking at the task library and async flow in .net 4/4.5 and as @Ferri suggests using a Sleep

Answer 2

You need use:

Thread.Sleep(5000);

But first you need add

using System.Threading;

or use

System.Threading.Thread.Sleep(5000);

on 5000 are the time in milliseconds

Sample

private void timerDelayWatcher_Tick(object sender, EventArgs e)
    {

        timerDelayWatcher.Stop();

        System.Threading.Thread.Sleep(5000);

            .......Do some stuff part2

    }

Take also care on loosing reference to the class containing the timerDelayWatcher member. If it happens the timer is disposed so no more events...
