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
