void AddFirst(System::Collections::Generic::LinkedListNode<T> ^ node);public void AddFirst(System.Collections.Generic.LinkedListNode<T> node);member this.AddFirst : System.Collections.Generic.LinkedListNode<'T> -> unitPublic Sub AddFirst (node As LinkedListNode(Of T))Parameters
- node
- LinkedListNode<T>
The new LinkedListNode<T> to add at the start of the LinkedList<T>.
Exceptions
node is null.
node belongs to another LinkedList<T>.
Examples
For an example that includes this method, see the LinkedList<T> class.
Remarks
LinkedList<T> accepts null as a valid Value for reference types and allows duplicate values.
If the LinkedList<T> is empty, the new node becomes the First and the Last.
This method is an O(1) operation.
