Name
Timer
Synopsis
This class can execute actions on a periodic basis. Actions can be
performed once or multiple times.
The constructor takes a
TimerCallback
delegate, a state
object
, a due time, and a period. Both due time
and period are measured in milliseconds.
Use the state argument to hold state information between delegate
calls, or pass in null
if you don’t have any
state to maintain. After the timer is created, it begins counting
down until the due time expired, and then it invokes the delegate.
The period is the amount of time to wait between delegate invocations
before resuming the countdown again.
If the period is zero, the timer executes only once. If either due
time or period are negative (and not equal to
Timeout.Infinite
), the constructor fails,
throwing an System.ArgumentOutOfRangeException
.
Change()
changes the due
time and period after the timer is created. Specify a due
time of Timeout.Infinite
to halt the timer. An
Infinite
period prevents the timer
from being raised repeatedly.
