C# | Check if a SortedSet object is a proper superset of the specified collection
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:
using System;
using System.Collections.Generic;
class GFG {
public static void Main()
{
SortedSet< int > mySet1 = new SortedSet< int >();
for ( int i = 0; i < 10; i++) {
mySet1.Add(i);
}
SortedSet< int > mySet2 = new SortedSet< int >();
mySet2.Add(3);
mySet2.Add(4);
mySet2.Add(5);
mySet2.Add(6);
Console.WriteLine(mySet2.IsProperSupersetOf(mySet1));
}
}

Example 2:
using System;
using System.Collections.Generic;
class GFG {
public static void Main()
{
SortedSet< string > mySet1 = new SortedSet< string >();
mySet1.Add( "A" );
mySet1.Add( "B" );
mySet1.Add( "C" );
mySet1.Add( "D" );
mySet1.Add( "A" );
SortedSet< string > mySet2 = new SortedSet< string >();
mySet2.Add( "B" );
mySet2.Add( "C" );
mySet2.Add( "D" );
mySet2.Add( "D" );
Console.WriteLine(mySet1.IsProperSupersetOf(mySet2));
}
}
