How to Iterate Over a Set in C# - Step by Step Examples



How to Iterate Over a Set in C# ?

Answer

To iterate over a set in C#, you can use a foreach loop to access each element in the set.



✐ Examples

1 Iterate Over a Set of Integers

In this example,

  1. We create a HashSet named numberSet and add some integers to it.
  2. We use a foreach loop to iterate over each element in the numberSet.
  3. Within the loop, we print each element to the console.

C# Program

using System;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        HashSet<int> numberSet = new HashSet<int>();
        numberSet.Add(10);
        numberSet.Add(20);
        numberSet.Add(30);

        foreach (int num in numberSet)
        {
            Console.WriteLine(num);
        }
    }
}

Output

10
20
30

2 Iterate Over a Set of Strings

In this example,

  1. We create a HashSet named nameSet and add some strings to it.
  2. We use a foreach loop to iterate over each element in the nameSet.
  3. Within the loop, we print each element to the console.

C# Program

using System;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        HashSet<string> nameSet = new HashSet<string>();
        nameSet.Add("Alice");
        nameSet.Add("Bob");
        nameSet.Add("Charlie");

        foreach (string name in nameSet)
        {
            Console.WriteLine(name);
        }
    }
}

Output

Alice
Bob
Charlie
