Timer.Change Method (Int64, Int64)

Changes the start time and the interval between method invocations for a timer, using 64-bit signed integers to measure time intervals.

Namespace:  System.Threading
Assembly:  mscorlib (in mscorlib.dll)

public bool Change(
	long dueTime,
	long period
)

Parameters

dueTime
Type: System.Int64
The amount of time to delay before the invoking the callback method specified when the Timer was constructed, in milliseconds. Specify Timeout.Infinite to prevent the timer from restarting. Specify zero (0) to restart the timer immediately.
period
Type: System.Int64
The time interval between invocations of the callback method specified when the Timer was constructed, in milliseconds. Specify Timeout.Infinite to disable periodic signaling.

Return Value

Type: System.Boolean
true if the timer was successfully updated; otherwise, false.

ExceptionCondition
ObjectDisposedException

The Timer has already been disposed.

ArgumentOutOfRangeException

The dueTime or period parameter is less than -1.

NotSupportedException

The dueTime or period parameter is greater than 4294967294.

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 Infinite, the callback method is never invoked; the timer is disabled, but can be re-enabled by calling Change and specifying a positive value for dueTime.

If period is zero (0) or Infinite, and dueTime is not Infinite, the callback method is invoked once; the periodic behavior of the timer is disabled, but can be re-enabled by calling Change and specifying a positive value for period.
