C# | Remove a specified item from 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>.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:

CSHARP

// 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:

CSHARP

// 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
