Print a string of fibonacci recursively in C#

Question

Can that be done with no while loops?

static void Main(string[] args)
{
    Console.WriteLine("Please enter a number");
    int number = Convert.ToInt32(Console.ReadLine());
    Console.WriteLine(" #" + Fibonacci(number));
}

public static int Fibonacci(int number)
{
    if (number <= 1)
    {
        return 1;
    }
    else
    {
        return Fibonacci(number - 2) + Fibonacci(number - 1);
    }
}

I can't even add a Console.WriteLine in the body of base case since it gets executed [number] number of times; Not sure how to do this without loops...

Answer 1

static void Main(string[] args)
{
    Console.WriteLine("Please enter a number");
    int number = Convert.ToInt32(Console.ReadLine());
    Fibonacci(0, 1, 1, number);
}   

public static void Fibonacci(int a, int b, int counter, int number)
{
    Console.WriteLine(a);
    if (counter < number) Fibonacci(b, a+b, counter+1, number);
}
