Represents a collection of Timeline objects (specific type animations). A TimelineCollection is the value of the Storyboard.Children property.

Remarks
Enumerating the collection in C# or Microsoft Visual Basic
A TimelineCollection 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<Timeline> explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable with a Timeline constraint.

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 Timeline located at the specified index. |
| GetMany(UInt32, Timeline[]) |
Retrieves multiple elements in a single pass through the iterator. |
| GetView() |
Gets an immutable view into the collection. |
| IndexOf(Timeline, UInt32) |
Retrieves the index of the specified item. |
| InsertAt(UInt32, Timeline) |
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(Timeline[]) |
