C# | Remove all elements from the SortedSet - Coding

SortedSet class represents the collection of objects in sorted order. This class comes under the System.Collections.Generic namespace. SortedSet<T>.Clear Method is used to remove the all elements from 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.Clear();

Here, mySortedSet is the name of the SortedSet.

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

Example 1:

// C# code to remove all the elements 
// from 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("A"); 
        mySortedSet.Add("B"); 
        mySortedSet.Add("C"); 
        mySortedSet.Add("D"); 
        mySortedSet.Add("E"); 
  
        // Displaying number of elements in mySortedSet 
        // before Removing all the elements 
        Console.WriteLine("Number of elements in mySortedSet are : " 
                                               + mySortedSet.Count); 
  
        // Displaying the element in mySortedSet 
        foreach(string str in mySortedSet) 
        { 
            Console.WriteLine(str); 
        } 
  
        // Removing all the elements from mySortedSet 
        mySortedSet.Clear(); 
  
        // Displaying number of elements in mySortedSet 
        // after Removing all the elements 
        Console.WriteLine("Number of elements in mySortedSet are : " 
                                               + mySortedSet.Count); 
    } 
} 

Output:

Number of elements in mySortedSet are : 5
A
B
C
D
E
Number of elements in mySortedSet are : 0

Example 2:

// C# code to remove all the elements 
// from 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 number of elements in mySortedSet 
        // before Removing all the elements 
        Console.WriteLine("Number of elements in mySortedSet are : " 
                                               + mySortedSet.Count); 
  
        // Displaying the element in mySortedSet 
        foreach(int i in mySortedSet) 
        { 
            Console.WriteLine(i); 
        } 
  
        // Removing all the elements from mySortedSet 
        mySortedSet.Clear(); 
  
        // Displaying number of elements in mySortedSet 
        // after Removing all the elements 
        Console.WriteLine("Number of elements in mySortedSet are : "
                                               + mySortedSet.Count); 
    } 
} 

Output:

Number of elements in mySortedSet are : 6
3
5
7
9
11
13
Number of elements in mySortedSet are : 0
