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(C

namespace Algorithms
{
    class Program
    {
        static void Main(string[] args)
        {
            string fibResult = "";
            fibResult =  FibCal(10);
            Console.WriteLine(fibResult);
            Console.ReadLine();
        }

        public static string FibCal(int n)
        {
            string series = "";
            int k, f1, f2 , f = 0;
            f1 = f2 = 1;
            if (n < 2) 
                return n.ToString();
            else
                for (k = 0; k < n; k++)
                {
                    f = f1 + f2;
                    f2 = f1;
                    f1 = f;
                    series += f.ToString() + ",";
                }

            return series;
        }

    }
}

Hope this helps
