How to Access Items in a Set in C# ?

Answer

To access items in a set in C#, you can use iteration or specific methods provided by the HashSet class.

✐ Examples

1 Access Items in a Set using Iteration

In this example,

We create a HashSet named stringSet containing strings.
We use a foreach loop to iterate over the elements in the set and print each element.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        HashSet<string> stringSet = new HashSet<string>();
        stringSet.Add("Apple");
        stringSet.Add("Banana");
        stringSet.Add("Orange");
        stringSet.Add("Grapes");

        foreach (var item in stringSet)
        {
            Console.WriteLine(item);
        }
    }
}

Output

Apple
Banana
Orange
Grapes

2 Access Items in a Set using Specific Methods

In this example,

We create a HashSet named numberSet containing integers.
We use the Contains method to check if an item exists in the set.
We use the Count property to get the number of elements in the set.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        HashSet<int> numberSet = new HashSet<int>();
        numberSet.Add(1);
        numberSet.Add(2);
        numberSet.Add(3);
        numberSet.Add(4);

        Console.WriteLine("Number of elements: " + numberSet.Count);
        Console.WriteLine("Does set contain 3? " + numberSet.Contains(3));
    }
}

Output

Number of elements: 4
Does set contain 3? True
