C# Exercise Program - Square of odd numbers

Question: Write a C# program to to calculate square of odd numbers in a given list

This program takes a list of numbers as input. It then filters out the list and returns only square of odd numbers from it.
Solution:

using System;
using System.Collections.Generic;

namespace CosmicLearn
{
    public static class CosmicExercise
    {
        public static List<int> GetOddNumbers(List<int> numbers)
        {
            List<int> oddNumbers = new List<int>();
            foreach(int num in numbers)
            {
                if (num % 2 == 1)
                {
                    oddNumbers.Add(num * num);
                }
            }
            return oddNumbers;
        }
        public static void Main(String[] args)
        {
            List<int> numbers = new List<int>();
            for (int i = 1; i <= 10; i++)
                numbers.Add(i);

            foreach(int oddNumber in GetOddNumbers(numbers))
            {
                Console.Write(oddNumber + " ");
            }
        }
    }
}
