How to find factorial of given number in c# using recursive function

Hello all, In  this program, we can get the factorial value of a number  using the recursive function in c#

using System;

using System.Collections.Generic;

using System.Text;



namespace testconsole

{

 class Program

 {

  static void Main(string[] args)

  {

   Console.WriteLine("Please enter a number");



   int number = Convert.ToInt32(Console.ReadLine());

   double factorial = factorial_RecursionValue(number);

   Console.WriteLine("factorial of : " + number + " = " + factorial);



   Console.ReadLine();







  }

  public static double factorial_RecursionValue(int number)

  {

   if (number == 1)

    return 1;

   else

    return number * factorial_RecursionValue(number - 1);



  }

 }

}
