C# | How to get a subset in a SortedSet

Last Updated : 11 Jul, 2025
SortedSet class represents the collection of objects in sorted order. This class comes under the System.Collections.Generic namespace. SortedSet<T>.GetViewBetween(T, T) method is used to return a view of a subset in a SortedSet<T>. 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: public virtual System.Collections.Generic.SortedSet<T> GetViewBetween (T lowerValue, T upperValue); Parameters: lowerValue: The lowest desired value in the view. upperValue: The highest desired value in the view. Return Value: A subset view that contains only the values in the specified range.
Exceptions :
  • ArgumentException: If lowerValue is more than upperValue according to the comparer.
  • ArgumentOutOfRangeException: A tried operation on the view was outside the range specified by lowerValue and upperValue.
Example 1: CSHARP 
// C# code to get the subset of a SortedSet
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("E");
        mySet1.Add("F");
        mySet1.Add("G");
        mySet1.Add("H");
        mySet1.Add("I");

        // Get the subset between "C" and "G"
        SortedSet<string> mySet2 = mySet1.GetViewBetween("C", "G");

        // Displaying the elements in the subset
        foreach(string str in mySet2)
        {
            Console.WriteLine(str);
        }
    }
}
Output: 
C
D
E
F
G
Example 2: CSHARP 
// C# code to get the subset of a SortedSet
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);
        }

        // Get the subset between "3" and "7"
        SortedSet<int> mySet2 = mySet1.GetViewBetween(3, 7);

        // Displaying the elements in the subset
        foreach(int i in mySet2)
        {
            Console.WriteLine(i);
        }
    }
}
Output: 
3
