ThreadPoolTimer.CreatePeriodicTimer(TimerElapsedHandler, TimeSpan, TimerDestroyedHandler) method

Applies to Windows and Windows Phone

Creates a periodic timer and specifies a method to call after the periodic timer is complete. The periodic timer is complete when the timer has expired without being reactivated, and the final call to handler has finished.

Syntax


public static ThreadPoolTimer CreatePeriodicTimer(
  TimerElapsedHandler handler, 
  TimeSpan period, 
  TimerDestroyedHandler destroyed
)

Parameters

handler

Type: TimerElapsedHandler

The method to call when the timer expires.

period

Type: System.TimeSpan [.NET] | Windows::Foundation::TimeSpan [C++]

The amount of time until the timer expires. The timer reactivates each time the period elapses, until the timer is canceled.

C++:  This amount of time is specified in ticks (100-nanosecond units) using the Windows::Foundation::TimeSpan structure.

JavaScript and C#:  This amount of time is specified using the System.TimeSpan structure. It can be specified in ticks, or it can be specified in milliseconds, seconds, and so on.

Note  A TimeSpan value of zero (or any value less than 1 millisecond) will cause the periodic timer to behave as a single-shot timer.

destroyed

Type: TimerDestroyedHandler

The method to call after the periodic timer is complete.

Return value

Type: ThreadPoolTimer

An instance of a periodic timer.
