How to add an Item to a Set in C# ?

Answer

In C#, you can add an item to a set (implemented using HashSet) using the Add() method.

✐ Examples

1 Add Integer to Set

In this example,

We create a HashSet named numbers containing some integer elements.
We use the Add() method of numbers to add a new integer element, such as 6, to the set.
Now, numbers contains the added element 6.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        HashSet<int> numbers = new HashSet<int>() { 1, 2, 3, 4, 5 };
        numbers.Add(6);
        foreach (int num in numbers)
        {
            Console.WriteLine(num);
        }
    }
}

Output

2 Add String to Set

In this example,

We create a HashSet named fruits containing some string elements.
We use the Add() method of fruits to add a new string element, such as "Orange", to the set.
Now, fruits contains the added element "Orange".

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        HashSet<string> fruits = new HashSet<string>() { "Apple", "Banana", "Cherry" };
        fruits.Add("Orange");
        foreach (string fruit in fruits)
        {
            Console.WriteLine(fruit);
        }
    }
}

Output

Apple
Banana
Cherry
Orange
