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

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 with a PointKeyFrame constraint.
Constructors
PointKeyFrameCollection() |
Initializes a new instance of the PointKeyFrameCollection class. |
Properties
Size |
Gets the size (count) of the collection. |
Methods
Append(PointKeyFrame) |
Adds a new item to the collection. |
Clear() |
Removes all items from the collection. |
First() |
Returns the iterator for iteration over the items in the collection. |
GetAt(UInt32) |
Returns the item located at the specified index. |
GetMany(UInt32, PointKeyFrame[]) |
Retrieves multiple elements in a single pass through the iterator. |
GetView() |
Gets an immutable view into the collection. |
IndexOf(PointKeyFrame, UInt32) |
Retrieves the index of the specified item. |
InsertAt(UInt32, PointKeyFrame) |
Inserts the specified item at the specified index. |
RemoveAt(UInt32) |
Removes the item at the specified index. |
RemoveAtEnd() |
Removes the last item in the collection. |
ReplaceAll(PointKeyFrame[]) |
Initially clears the collection, then inserts the provided array as new items. |
SetAt(UInt32, PointKeyFrame) |
Sets the value at the specified index to the PointKeyFrame value specified. |
