C# | Get the number of elements in the 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>.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:

CSHARP

// 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:

CSHARP

// 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
