C# | How to create 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. 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:

SortedSet<T> mySortedSet = new SortedSet<T>();

Here, mySortedSet is the name of the SortedSet and T is Type Parameter. Below given are some examples to understand the implementation in a better way: Example 1:

CSHARP

// C# code to create a SortedSet
using System;
using System.Collections.Generic;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a SortedSet of integers
        SortedSet<int> mySortedSet = new SortedSet<int>();

        // Adding elements in mySortedSet
        for (int i = 1; i <= 6; i++) {
            mySortedSet.Add(2 * i + 1);
        }

        // Displaying elements in mySortedSet
        Console.WriteLine("The elements in mySortedSet are : ");

        // Displaying the element in mySortedSet
        foreach(int i in mySortedSet)
        {
            Console.WriteLine(i);
        }
    }
}

Output:

The elements in mySortedSet are : 
3
5
7
9
11
13

Example 2:

CSHARP

// C# code to create a SortedSet
using System;
using System.Collections.Generic;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a SortedSet of strings
        SortedSet<string> mySortedSet = new SortedSet<string>();

        // Adding elements in mySortedSet
        mySortedSet.Add("H");
        mySortedSet.Add("E");
        mySortedSet.Add("L");
        mySortedSet.Add("L");
        mySortedSet.Add("O");

        // Displaying elements in mySortedSet
        Console.WriteLine("The elements in mySortedSet are : ");

        // Displaying the element in mySortedSet
        foreach(string str in mySortedSet)
        {
            Console.WriteLine(str);
        }
    }
}

Output:

The elements in mySortedSet are : 
E
H
L
O
