LinkedList<T>.AddLast Method (T)

Adds a new node containing the specified value at the end of the LinkedList<T>.

Namespace:  System.Collections.Generic
Assembly:  System (in System.dll)
public LinkedListNode<T> AddLast(
	T value
)

Parameters

value
Type: T
The value to add at the end of the LinkedList<T>.

Return Value

Type: System.Collections.Generic.LinkedListNode<T>
The new LinkedListNode<T> containing value.

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.

The following code example and output demonstrate the AddLast method. The code example removes the last node in a linked list of strings, uses the AddLast(T) method overload to add a new node to the end of the list, marks that node, removes it, and inserts it at the beginning of the list.

This code and output are part of a larger example provided for the LinkedList<T> class.


// Move the last node to be the first node.
mark1 = sentence.Last;
sentence.RemoveLast();
sentence.AddFirst(mark1);
