Check if HashSet and the specified collection contain the same elements in C#

Csharp Server Side Programming Programming

To check if HashSet and the specified collection contain the same elements, the code is as follows −

Example

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main() {
      HashSet<string> set1 = new HashSet<string>();
      set1.Add("One");
      set1.Add("Two");
      set1.Add("Three");
      set1.Add("Four");
      set1.Add("Five");
      set1.Add("Six");
      set1.Add("Seven");
      HashSet<string> set2 = new HashSet<string>();
      set2.Add("One");
      set2.Add("Two");
      set2.Add("Three");
      set2.Add("Four");
      Console.WriteLine("Does it contains the same elements? = "+set1.SetEquals(set2));
   }
}

Output

This will produce the following output −

Does it contain the same elements? = False

Example

Let us see another example −

Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main() {
      HashSet<int> set1 = new HashSet<int>();
      set1.Add(100);
      set1.Add(200);
      set1.Add(300);
      set1.Add(400);
      set1.Add(500);
      set1.Add(600);
      HashSet<int> set2 = new HashSet<int>();
      set2.Add(100);
      set2.Add(200);
      set2.Add(300);
      set2.Add(400);
      set2.Add(500);
      set2.Add(600);
      Console.WriteLine("Does it contain the same elements? = "+set1.SetEquals(set2));
   }
}

Output

This will produce the following output −

Does it contain the same elements? = True
