C# | Remove a specified item from SortedSet

SortedSet class represents the collection of objects in sorted order. This class comes under the System.Collections.Generic namespace. SortedSet<T>.Remove(T) Method is used to remove a specified item 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:

public bool Remove (T item);

Here, item is the specified item which is to be removed from the SortedSet.

Note: If the SortedSet<T> object does not contain the specified element, the object remains unchanged and no exception is thrown.

Example 1:

// C# code to remove a specified element
// from 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(2);
        mySortedSet.Add(4);
        mySortedSet.Add(6);
        mySortedSet.Add(8);
        mySortedSet.Add(10);

        // Removing element "4" if found
        mySortedSet.Remove(4);

        // Displaying the elements in mySortedSet
        foreach(int i in mySortedSet)
        {
            Console.WriteLine(i);
        }

        Console.WriteLine("After Using Method");

        // Removing element "14" if found
        mySortedSet.Remove(14);

        // Displaying the element in mySortedSet
        foreach(int i in mySortedSet)
        {
            Console.WriteLine(i);
        }
    }
}

Output:

2
6
8
10
After Using Method
2
6
8
10

Example 2:

// C# code to remove the specified
// element 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");

        // Removing element "C" if found
        mySortedSet.Remove("C");

        // Displaying the element in mySortedSet
        foreach(string str in mySortedSet)
        {
            Console.WriteLine(str);
        }
    }
}

Output:

A
B
D
E
