Divisors Dont learn it, it was made for fun

namespace DivisorsV1;

static class Program
{
    private static List<int> Divisors(int number)
    {
        List<int> divisor = new List<int>();

        foreach (int divisorNumber in Enumerable.Range(1, number))

        }
        divisor.RemoveAll(divisorNumber => divisorNumber == -1);

        return divisor;
    }

    private static void Main()
    {
        string? temp = Console.ReadLine();
        int number = int.TryParse(temp, out int num) ? num : 0;
        foreach (int divisor in Divisors(number).SkipLast(1))
        {

        }
