C# | How to get a subset in a SortedSet

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>.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);
        }
    }
}
