Get the number of nodes contained in LinkedList in C#

CsharpServer Side ProgrammingProgramming

To get the number of nodes contained in the 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");
      list.AddLast("G");
      list.AddLast("H");
      list.AddLast("I");
      list.AddLast("J");
      Console.WriteLine("Count of nodes = " + list.Count);
      Console.WriteLine("First Node = "+list.First.Value);
      list.Clear();
      Console.WriteLine("Count of nodes (updated) = " + list.Count);
   }
}

Output

This will produce the following output −

Count of nodes = 10
First Node = A
Count of nodes (updated) = 0

Example

Let us see another example −

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(String[] args) {
      LinkedList<String> list1 = new LinkedList<String>();
      list1.AddLast("One");
      list1.AddLast("Two");
      list1.AddLast("Three");
      list1.AddLast("Four");
      list1.AddLast("Five");
      Console.WriteLine("Elements in LinkedList1...");
      foreach (string res in list1) {
         Console.WriteLine(res);
      }
      LinkedList<String> list2 = new LinkedList<String>();
      list2.AddLast("India");
      list2.AddLast("US");
      list2.AddLast("UK");
      list2.AddLast("Canada");
      list2.AddLast("Poland");
      list2.AddLast("Netherlands");
      Console.WriteLine("Elements in LinkedList2...");
      foreach (string res in list2) {
         Console.WriteLine(res);
      }
      LinkedList<String> list3 = new LinkedList<String>();
      Console.WriteLine("Count of nodes in LinkedList3 = "+list3.Count);
      list3 = list2;
      Console.WriteLine("Count of nodes in LinkedList3 (Updated) = "+list2.Count);
      Console.WriteLine("Is LinkedList3 equal to LinkedList2? = "+list3.Equals(list2));
   }
}

Output

This will produce the following output −

Elements in LinkedList1...
One
Two
Three
Four
Five
Elements in LinkedList2...
India
US
UK
Canada
Poland
Netherlands
Count of nodes in LinkedList3 = 0
Count of nodes in LinkedList3 (Updated) = 6
Is LinkedList3 equal to LinkedList2? = True
