Check If Two List Objects Are Equal in C#

To check if two List 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){
      List<string> list1 = new List<string>();
      list1.Add("One");
      list1.Add("Two");
      list1.Add("Three");
      list1.Add("Four");
      list1.Add("Five");
      Console.WriteLine("Elements in List1...");
      foreach (string res in list1){
         Console.WriteLine(res);
      }
      List<string> list2 = new List<string>();
      list2.Add("India");
      list2.Add("US");
      list2.Add("UK");
      list2.Add("Canada");
      list2.Add("Poland");
      list2.Add("Netherlands");
      Console.WriteLine("Elements in List2...");
      foreach (string res in list2){
         Console.WriteLine(res);
      }
      Console.WriteLine("Is List2 equal to List1? = "+list2.Equals(list1));
   }
}

Output

This will produce the following output −

Elements in List1...
One
Two
Three
Four
Five
Elements in List2...
India
US
UK
Canada
Poland
Netherlands
Is List2 equal to List1? = False

Example

Let us see another example −

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(String[] args){
      List<string> list1 = new List<string>();
      list1.Add("One");
      list1.Add("Two");
      list1.Add("Three");
      list1.Add("Four");
      list1.Add("Five");
      Console.WriteLine("Elements in List1...");
      foreach (string res in list1){
         Console.WriteLine(res);
      }
      List<string> list2 = new List<string>();
      list2.Add("India");
      list2.Add("US");
      list2.Add("UK");
      list2.Add("Canada");
      list2.Add("Poland");
      list2.Add("Netherlands");
      Console.WriteLine("Elements in List2...");
      foreach (string res in list2){
         Console.WriteLine(res);
      }
      List<string> list3 = new List<string>();
      list3 = list2;
      Console.WriteLine("Is List3 equals to List2? = "+list3.Equals(list2));
   }
}

Output

This will produce the following output −

Elements in List1...
One
Two
Three
Four
Five
Elements in List2...
India
US
UK
Canada
Poland Netherlands
Is List3 equals to List2? = True
