LinkedList AddAfter method in C#

Set a LinkedList.

int [] num = {1, 2, 3, 4, 5}; LinkedList<int> list = new LinkedList<int>(num);

Now add a node at the end using AddLast() method.

var newNode = list.AddLast(20);

To add a node after the above added node, use the AddAfter() method.

list.AddAfter(newNode, 30);

Example

 Live Demo

using System; using System.Collections.Generic; class Demo {    static void Main() {       int [] num = {1, 2, 3, 4, 5};       LinkedList<int> list = new LinkedList<int>(num);       foreach (var n in list) {          Console.WriteLine(n);       }       // adding a node at the end       var newNode = list.AddLast(20);       // adding a new node after the node added above       list.AddAfter(newNode, 30);       Console.WriteLine("LinkedList after adding new nodes...");       foreach (var n in list) {          Console.WriteLine(n);       }    } }

Output

1 2 3 4 5 LinkedList after adding new nodes... 1 2 3 4 5 20 30
