Add New Node at the End of Linked List in C#

To add new node or value at the end of LinkedList, the code is as follows −

Example

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main() {
      LinkedList<String> list = new LinkedList<String>();
      list.AddLast("A");
      list.AddLast("B");
      list.AddLast("C");
      list.AddLast("D");
      list.AddLast("E");
      list.AddLast("F");
      Console.WriteLine("Count of nodes = " + list.Count);
      Console.WriteLine("Elements in LinkedList...");
      foreach (string res in list) {
         Console.WriteLine(res);
      }
      list.AddLast("G");
      list.AddLast("H");
      list.AddLast("I");
      Console.WriteLine("Count of nodes = " + list.Count);
      Console.WriteLine("Elements in LinkedList...");
      foreach (string res in list) {
         Console.WriteLine(res);
      }
   }
}

Output

This will produce the following output −

Count of nodes = 6
Elements in LinkedList...
A
B
C
D
E
F
Count of nodes = 9
Elements in LinkedList...
A
B
C
D
E
F
G
H
I

Example

Let us see another example −

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main() {
      LinkedList<int> list = new LinkedList<int>();
      list.AddLast(100);
      list.AddLast(200);
      list.AddLast(300);
      Console.WriteLine("Count of nodes = " + list.Count);
      Console.WriteLine("Elements in LinkedList...");
      foreach (int res in list) {
         Console.WriteLine(res);
      }
      list.AddLast(400);
      list.AddLast(500);
      list.AddLast(600);
      Console.WriteLine("Count of nodes = " + list.Count);
      Console.WriteLine("Elements in LinkedList...");
      foreach (int res in list) {
         Console.WriteLine(res);
      }
   }
}

Output

This will produce the following output −

Count of nodes = 3
Elements in LinkedList...
100
200
300
Count of nodes = 6
Elements in LinkedList...
100
200
300
400
500
600
