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
