Clear Removes all items from the collection.
Contains [C#, VB]Determines whether an element is in the collection.
CopyTo [C#, VB]Copies the elements of the collection to an array, starting at a particular array index.
First [C++]Returns the iterator for iteration over the items in the collection.
GetAt [C++]Returns the Timeline located at the specified index.
GetMany [C++]Retrieves multiple elements in a single pass through the iterator.
GetView [C++]Gets an immutable view into the collection.
IndexOf [C++]Retrieves the index of the specified item.
IndexOf [C#, VB]Determines the index of a specific item in the collection.

Properties

The TimelineCollection class has these properties.

PropertyAccess typeDescription

Count [C#, VB]

Read-onlyGets the number of elements contained in the collection.

IsReadOnly [C#, VB]

Read-onlyGets a value indicating whether the collection is read-only.

Item [C#, VB]

Read/writeGets or sets the element at the specified index.

Size [C++]

Read-onlyGets the size (count) of the collection.

 

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<T> with a Timeline constraint.
