LinkedList(Of T).ICollection(Of T).Add Method

Adds an item at the end of the ICollection(Of T).

Namespace:  System.Collections.Generic
Assembly:  System (in System.dll)

Private Sub Add ( _
	value As T _
) Implements ICollection(Of T).Add


Type: T
The value to add at the end of the ICollection(Of T).


ICollection(Of T).Add(T)

LinkedList(Of T) accepts Nothing as a valid Value for reference types and allows duplicate values.

If the LinkedList(Of 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 demonstrates that when a LinkedList(Of T) is cast to ICollection(Of T), the LinkedListSystem#Collections#Generic#ICollection{`0}#Add(UTP) method can be used to add a new node to the end of the linked list. The code example removes the last node in a linked list of strings, and adds a new node.

This code and output are part of a larger example provided for the LinkedList(Of T) class.

' When the linked list is cast to ICollection(Of String),
' the Add method adds a node to the end of the list.
