Как искать диапазон значений в массиве C#

Question

Я все еще новичок в C#, и я застрял на одной из функций в моем коде. Я не могу заставить его возвращать значения в case6, искать возраст в пределах диапазона (min-max), все остальное работает нормально. Что там не так?

class Buss
{
    private string name = "minibuss";
    public int[] passengers = new int[9];
    public int passengerNum;

    public void Run()  //that´s the menu, you fill in age and then could go through array with other options
    {
        Console.WriteLine("THE miniBUSS SIMULATOR");

        int temp = 0;
        do
        {
            Console.WriteLine("Choose an alternative (starting with 1 ;-))");
            Console.WriteLine("1. Fill in pass");
            Console.WriteLine("2. Print passengers age");
            Console.WriteLine("3. Show total age of all passanger");
            Console.WriteLine("4. Average age of passsangers");
            Console.WriteLine("5. Who´s oldest");
            Console.WriteLine("6. Show passangers within range of years");
            Console.WriteLine("7. Sort passangers by age");
            Console.WriteLine("Hit 0 to exit\n");
            temp = int.Parse(Console.ReadLine());

            switch (temp)

необходимо отложить перерыв, который нарушает l oop:

    for (int i = 0; i < passengers.Length; i++)            
    {
        if (passengers[i] >=  keyMin && passengers[i] <= keyMax)   

        {
            Console.WriteLine("Those are the passangers within range: " + i);
        }
   ---> //break;
    }
