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