Timeline.GetNaturalDuration Method

Returns the length of a single iteration of this Timeline.

Namespace:  System.Windows.Media.Animation
Assembly:  PresentationCore (in PresentationCore.dll)
protected internal Duration GetNaturalDuration(
	Clock clock
)

Parameters

clock
Type: System.Windows.Media.Animation.Clock

The Clock that was created for this Timeline.

Return Value

Type: System.Windows.Duration
The length of a single iteration of this Timeline, or Automatic if the natural duration is unknown.

This method should only be called when the Duration property is set to Automatic. If Duration is Automatic, the natural duration is determined by that particular class's implementation of GetNaturalDurationCore.

If GetNaturalDuration returns Automatic, it means that the natural duration is unknown, which implies a natural duration of Forever. Such is the case for streaming media.

Note that passing this method a clock other than the one that was created for this timeline is possible, but will provide unreliable results.
