C# | Get the last node of the LinkedList<T>
LinkedList<T>.Last property is used to get the last node of the LinkedList<T>.
Syntax:
public System.Collections.Generic.LinkedListNode Last { get; }
Return Value: The last LinkedListNode<T> of the LinkedList<T>.
Below given are some examples to understand the implementation in a better way:
Example 1:
// C# code to get the last // node of the LinkedList using System; using System.Collections; using System.Collections.Generic; class GFG { // Driver code public static void Main() { // Creating a LinkedList of Strings LinkedList<String> myList = new LinkedList<String>(); // Adding nodes in LinkedList myList.AddLast( "A" ); myList.AddLast( "B" ); myList.AddLast( "C" ); myList.AddLast( "D" ); myList.AddLast( "E" ); // To get the last node of the LinkedList if (myList.Count > 0) Console.WriteLine(myList.Last.Value); else Console.WriteLine( "LinkedList is empty" ); } } |
Output:
E
Example 2:
// C# code to get the last // node of the LinkedList using System; using System.Collections; using System.Collections.Generic; class GFG { // Driver code public static void Main() { // Creating a LinkedList of Integers LinkedList< int > myList = new LinkedList< int >(); // To get the last node of the LinkedList if (myList.Count > 0) Console.WriteLine(myList.Last.Value); else Console.WriteLine( "LinkedList is empty" ); } } |
Output:
LinkedList is empty
Note:
- LinkedList accepts null as a valid Value for reference types and allows duplicate values.
- If the LinkedList is empty, the First and Last properties contain null.
- Retrieving the value of this property is an O(1) operation.
