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.
Assembly: mscorlib (in mscorlib.dll)
- 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.
Return ValueType: System.Boolean
true if the timer was successfully updated; otherwise, false.
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 Timeout.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 Timeout.Infinite, and dueTime is not Timeout.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.
