LinkedList AddAfter method in C#

CsharpProgrammingServer Side Programming

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);
      }
   }
}
