LinkedList AddFirst method in C#
In a Linked List, if you want to add a node at the first position, use AddFirst method.
Let’s first set a LinkedList.
string [] students = {"Jenifer","Angelina","Vera"}; LinkedList<string> list = new LinkedList<string>(students);
Now, to add an element as a first node, use AddFirst() method.
List.AddFirst(“Natalie”);
Example
using System; using System.Collections.Generic; class Demo { static void Main() { string [] students = {"Jenifer","Angelina","Vera"}; LinkedList<string> list = new LinkedList<string>(students); foreach (var stu in list) { Console.WriteLine(stu); } // add a node Console.WriteLine("Node added at the first position..."); list.AddFirst("Natalie"); foreach (var stu in list) { Console.WriteLine(stu); } } }
Output
Jenifer Angelina Vera Node added at the first position... Natalie Jenifer Angelina Vera
