Parameters

dueTime

A TimeSpan representing the amount of time to delay before invoking the callback method specified when the System.Threading.Timer was constructed. Specify negative one (-1) milliseconds to prevent the timer from restarting. Specify zero (0) to restart the timer immediately.

period

The time interval between invocations of the callback method specified when the System.Threading.Timer was constructed. Specify negative one (-1) milliseconds to disable periodic signaling.

Returns

true if the timer was successfully updated; otherwise, false.

Exceptions

Type	Reason
ArgumentOutOfRangeException	dueTime or period is negative and is not equal to Timeout.Infinite .

Remarks

The callback method is invoked once after dueTime elapses, and thereafter each time the time interval specified by period elapses.

If dueTime is zero (0), the callback method is invoked immediately. If dueTime is negative one (-1) milliseconds, the callback method is never invoked; the timer is disabled, but can be re-enabled by calling Timer.Change(int, int) and specifying a positive value for dueTime.

If period is zero (0) or negative one (-1) milliseconds, and dueTime is positive, the callback method is invoked once; the periodic behavior of the timer is disabled, but can be re-enabled by calling Timer.Change(int, int) and specifying a value greater than zero for period.
