Check if two SortedSet objects are equal in C#

To check if two SortedSet objects are equal, the code is as follows −

Example

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      SortedSet<int> set1 = new SortedSet<int>();
      set1.Add(100);
      set1.Add(200);
      set1.Add(300);
      set1.Add(400);
      Console.WriteLine("Elements in SortedSet1...");
      foreach (int res in set1) {
         Console.WriteLine(res);
      }
      Console.WriteLine("Does the SortedSet1 contains the element 400? = "+set1.Contains(400));
      SortedSet<int> set2 = new SortedSet<int>();
      set2.Add(100);
      set2.Add(200);
      set2.Add(300);
      set2.Add(400);
      Console.WriteLine("Elements in SortedSet2...");
      foreach (int res in set2){
         Console.WriteLine(res);
      }
      Console.WriteLine("Does the SortedSet2 contains the element 500? = "+set2.Contains(500));
      Console.WriteLine("Are both the sets equal? = "+set1.Equals(set2));
   }
}

Output

This will produce the following output −

Elements in SortedSet1...
100
200
300
400
Does the SortedSet1 contains the element 400? = True
Elements in SortedSet2...
100
200
300
400
Does the SortedSet2 contains the element 500? = False
Are both the sets equal? = False

Example

Let us see another example −

 Live Demo

using System;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      SortedSet<int> set1 = new SortedSet<int>();
      set1.Add(10);
      set1.Add(15);
      set1.Add(30);
      set1.Add(50);
      set1.Add(75);
      set1.Add(100);
      set1.Add(150);
      Console.WriteLine("Elements in SortedSet1...");
      foreach (int res in set1){
         Console.WriteLine(res);
      }
      Console.WriteLine("Does the SortedSet1 contains the element 400? = "+set1.Contains(400));
      SortedSet<int> set2 = new SortedSet<int>();
      set2.Add(25);
      set2.Add(50);
      set2.Add(100);
      set2.Add(200);
      set2.Add(400);
      set2.Add(500);
      Console.WriteLine("Elements in SortedSet2...");
      foreach (int res in set2){
         Console.WriteLine(res);
      }
      set2 = set1;
      Console.WriteLine("Are both the sets equal? = "+set1.Equals(set2));
   }
}

Output

This will produce the following output −

Elements in SortedSet1...
10
15
30
50
75
100
150
Does the SortedSet1 contains the element 400? = False
Elements in SortedSet2...
25
50
100
200
400
500
Are both the sets equal? = True
