PointKeyFrameCollection PointKeyFrameCollection PointKeyFrameCollection Class

Represents a collection of PointKeyFrame objects that can be individually accessed by index. PointKeyFrameCollection is the value of the KeyFrames property.

Syntax

Declaration

public sealed class PointKeyFrameCollectionpublic sealed class PointKeyFrameCollectionPublic NotInheritable Class PointKeyFrameCollection

Remarks

Enumerating the collection in C# or Microsoft Visual Basic

A PointKeyFrameCollection is enumerable, so you can use language-specific syntax such as foreach in C# to enumerate the items in the collection. The compiler does the type-casting for you and you won't need to cast to IEnumerable<PointKeyFrame> explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable<T> with a PointKeyFrame constraint.
