The following example creates two disparate HashSet objects and compares them to each another.

//from   w w  w.j a v a  2  s  .  c  o m
using System;
using System.Collections.Generic;
public class MainClass{
  public static void Main(String[] argv){  
    HashSet<int> lowNumbers = new HashSet<int>();
    HashSet<int> allNumbers = new HashSet<int>();

    for (int i = 1; i < 5; i++)
    {
        lowNumbers.Add(i);
    }

    for (int i = 0; i < 10; i++)
    {
        allNumbers.Add(i);
    }

    Console.WriteLine(allNumbers.SetEquals(lowNumbers));

  }
}
    

The code above generates the following result.
