Public Interface IImmutableList(Of T)
Implements IEnumerable(Of T), IReadOnlyCollection(Of T), IReadOnlyList(Of T)

Type Parameters

T

The type of elements in the list.

Derived: System.Collections.Immutable.ImmutableArray<T>

System.Collections.Immutable.ImmutableList<T>

Implements: IEnumerable<T> IReadOnlyCollection<T> IReadOnlyList<T> IEnumerable

Remarks

When you add or remove items from an IImmutableList<T>, a copy of the original list is created, with the changes applied. Incremental changes to a list share as much memory as possible with earlier versions of a list and enable garbage collection to clean up any unique list data that is no longer being referenced.

For information on creating an IImmutableList<T> implementation, see System.Collections.Immutable.ImmutableList<T>.
