C# | Add element to SortedSet

SortedSet class represents the collection of objects in sorted order. This class comes under the System.Collections.Generic namespace. SortedSet.Add(T) Method is used to add an element to the set and returns a value that specify if it was successfully added 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:

public bool Add (T item);

Parameter:

item: The element which is added to the set.

Return Value: True if item is added to the set, otherwise False.

Example 1:

// C# code to add element to 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 = 2; i < 7; i++) {
            mySortedSet.Add(i * 2);
        }

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

Output:

4
6
8
10
12

Example 2:

// C# code to add element to 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
        mySortedSet.Add(4);
        mySortedSet.Add(5);
        mySortedSet.Add(6);

        // Trying to add some duplicate
        // elements in mySortedSet
        mySortedSet.Add(6);
        mySortedSet.Add(6);
        mySortedSet.Add(6);
        mySortedSet.Add(7);

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

Output:

4
5
