我只是运动有一些问题..我必须编写一个程序,询问用户N的值,然后计算N!使用递归.我写了类似的东西

 namespace ConsoleApplication19
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("This program will calculate a factorial of random number. Please type a number");
            String inputText = Console.ReadLine();
            int N = int.Parse(inputText);


        String outputText = "Factorial of " + N + "is: ";
        int result = Count(ref N);
        Console.WriteLine(outputText + result);
        Console.ReadKey();
    }

    private static object Count(ref int N)
    {
        for (int N; N > 0; N++)
        {
            return (N * N++);
        }
    }
}

问题在于"int result = Count(ref …
