C# Program to add a node after the given node in a Linked List

Set a LinkedList and add elements.

string [] students = {"Beth","Jennifer","Amy","Vera"}; LinkedList<string> list = new LinkedList<string>(students);

Firstly, add a new node at the end.

var newNode = list.AddLast("Emma");

Now, use the AddAfter() method to add a node after the given node.

list.AddAfter(newNode, "Matt");

The following is the complete code.

Example

 Live Demo

using System; using System.Collections.Generic; class Demo {    static void Main() {       string [] students = {"Beth","Jennifer","Amy","Vera"};       LinkedList<string> list = new LinkedList<string>(students);       foreach (var stu in list) {          Console.WriteLine(stu);       }       // adding a node at the end       var newNode = list.AddLast("Emma");       // adding a new node after the node added above       list.AddAfter(newNode, "Matt");       Console.WriteLine("LinkedList after adding new nodes...");       foreach (var stu in list) {          Console.WriteLine(stu);       }    } }

Output

Beth Jennifer Amy Vera LinkedList after adding new nodes... Beth Jennifer Amy Vera Emma Matt
