LinkedList<T>.AddFirst Method
Definition
Adds a new node or value at the start of the LinkedList<T>.
Overloads
AddFirst(LinkedListNode<T>) |
Adds the specified new node at the start of the LinkedList<T>. |
AddFirst(T) |
Adds a new node containing the specified value at the start of the LinkedList<T>. |
AddFirst(LinkedListNode<T>)
Adds the specified new node at the start of the LinkedList<T>.
public:
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> -> unit
Public 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.
