C# | Check if a SortedSet object is a proper superset of the specified collection

Last Updated : 01 Feb, 2019

SortedSet class represents the collection of objects in sorted order. This class comes under the System.Collections.Generic namespace. SortedSet<T>.IsProperSupersetOf(IEnumerable<T>) method is used to check whether a SortedSet object is a proper superset of the specified collection or not.

Properties:

In C#, SortedSet class can be used to store, remove or view elements.
It maintains ascending order and does not store duplicate elements.
It is suggested to use SortedSet class if you have to store unique elements and maintain ascending order.

Syntax:

mySet1.IsProperSupersetOf(mySet2);

Here, mySet1 and mySet2 are the objects of two SortedSet.

Return Value: This method returns True if the SortedSet<T> object is a proper superset of other, otherwise returns False.

Exception: This method will give ArgumentNullException if the SortedSet is null.

Below programs illustrate the use of SortedSet<T>.IsProperSupersetOf(IEnumerable<T>) method:

Example 1:

// C# code to Check if a SortedSet is a
// proper superset of the specified collection
using System;
using System.Collections.Generic;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Creating a SortedSet of integers
        SortedSet<int> mySet1 = new SortedSet<int>();
  
        // Inserting elements in SortedSet
        for (int i = 0; i < 10; i++) {
            mySet1.Add(i);
        }
  
        // Creating a SortedSet of integers
        SortedSet<int> mySet2 = new SortedSet<int>();
  
        // Inserting elements in SortedSet
        mySet2.Add(3);
        mySet2.Add(4);
        mySet2.Add(5);
        mySet2.Add(6);
  
        // Check if a SortedSet is a proper superset
        // of the specified collection
        // It should return false as SortedSet mySet2
        // is not a proper superset of SortedSet mySet1
        Console.WriteLine(mySet2.IsProperSupersetOf(mySet1));
    }
}

Output:

False

Example 2:

// C# code to Check if a SortedSet is a
// proper superset of the specified collection
using System;
using System.Collections.Generic;
  
class GFG {
  
    // Driver code
    public static void Main()
    {
  
        // Creating a SortedSet of strings
        SortedSet<string> mySet1 = new SortedSet<string>();
  
        // Inserting elements in SortedSet
        mySet1.Add("A");
        mySet1.Add("B");
        mySet1.Add("C");
        mySet1.Add("D");
        mySet1.Add("A");
  
        // Creating a SortedSet of strings
        SortedSet<string> mySet2 = new SortedSet<string>();
  
        // Inserting elements in SortedSet
        mySet2.Add("B");
        mySet2.Add("C");
        mySet2.Add("D");
        mySet2.Add("D");
  
        // Check if a SortedSet is a proper superset
        // of the specified collection
        // It should return true as SortedSet mySet1
        // is proper superset of SortedSet mySet2
        Console.WriteLine(mySet1.IsProperSupersetOf(mySet2));
    }
}

Output:

True
