assign a double value to timer interval

Question

I am trying to assign a huge number of (milliseconds) to a timer interval, but i got this crash on "timer.Enabled = true" line !

The Exception Says :

An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in mscorlib.dll

Additional information: Number must be either non-negative and less than or equal to Int32.MaxValue or -1.

This is my code:

    CurrencyTimer.Interval = 2626086891.0;
    CurrencyTimer.Enabled = true;
    CurrencyTimer.AutoReset = true;
    CurrencyTimer.Elapsed += new System.Timers.ElapsedEventHandler(TimerWorker);
    CurrencyTimer.Start();

The Exception point to this line : CurrencyTimer.Enabled = true; Thanks,

You want to wait for `30` days???? `2626086891/1000/60/60/24 = 30...` — M.kazem Akhgary, Dec 22 '16 at 13:20

The exception (and the documentation) is fairly clear about that the interval has to be between 0 and int.MaxValue. So, don't assign a value larger than that.

For very long timer intervals you may have to split your interval in shorter intervals and count yourself. I'd also be curious why you think you need a 30-day timer interval ...

but the interval type is double ! – Qutaiba Dec 22 '16 at 13:20
you should use schedulers in windows instead or some kind of schedulers like that @Qutaiba – M.kazem Akhgary Dec 22 '16 at 13:22
Reading the docs sometimes helps. _The value must be greater than zero, and less than or equal to Int32.MaxValue_ – Steve Dec 22 '16 at 13:22
@Qutaiba: So what? An array index is also an `int` and the valid values are only a subset of the full range. That's not unusual at all. – Joey Dec 22 '16 at 13:22
@Steve yes i know that, but the interval type is double ! – Qutaiba Dec 22 '16 at 13:23

@Qutaiba oh well, then look at this http://stackoverflow.com/questions/11610611/why-is-the-data-type-of-system-timers-timer-interval-a-double – Steve Dec 22 '16 at 13:25

Use:

Threading.Timer

The constructor has several overloads two of which accept TimeSpan or Int64 values. The documentation does not mention limits on the values except for the intrinsic limitations of the data types.
