Check If Two LinkedList Objects Are Equal in C#

To check if two LinkedList objects are equal, the code is as follows −

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>();
      list3 = list2;
      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
Is LinkedList3 equal to LinkedList2? = True

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);
      }
      Console.WriteLine("Is LinkedList2 equal to LinkedList1? = "+list2.Equals(list1));
   }
}

Output

This will produce the following output −

Elements in LinkedList1...
One
Two
Three
Four
Five

Elements in LinkedList2...
India
US
UK
Canada
Poland
Netherlands
Is LinkedList2 equal to LinkedList1? = False
