C# | Get the number of elements in the SortedSet

SortedSet class represents the collection of objects in sorted order. This class comes under the System.Collections.Generic namespace. SortedSet<T>.Count Property is used to get the number of elements in the SortedSet.

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:

mySortedSet.Count

Here, mySortedSet is a SortedSet.

Below given are some examples to understand the implementation in a better way:

Example 1:

// C# code to get the number of
// elements in the 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(1);
        mySortedSet.Add(2);
        mySortedSet.Add(3);
        mySortedSet.Add(4);
        mySortedSet.Add(5);

        // Displaying the number of elements in
        // the SortedSet using "Count" function
        Console.WriteLine("The number of elements in mySortedSet are: "
                                                  + mySortedSet.Count);
    }
}

Output:

The number of elements in mySortedSet are: 5

Example 2:

// C# code to get the number of
// elements in the 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("Hey");
        mySortedSet.Add("GeeksforGeeks");
        mySortedSet.Add("and");
        mySortedSet.Add("Geeks Classes");

        // Displaying the number of elements in
        // the SortedSet using "Count" function
        Console.WriteLine("The number of elements in mySortedSet are: "
                                                   + mySortedSet.Count);
    }
}

Output:

The number of elements in mySortedSet are: 4
