C# | Get the number of elements in the SortedSet - Coding

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
