{

// Convert the input arguments to numbers:

int num = int.Parse(args[0]);

System.

Console.WriteLine("The Factorial of {0} is {1}.", num, Functions.Factorial(num));

return 0;

}

try this one: using System; using System.Collections.Generic; using System.Text; class Class2 { static int Fact(int n) { if (n return 1; return n * Fact(n - 1); } static void Main(string[] args) { Console.Write(Enter a Number to find factorial: ); int n = Convert.ToInt32(Console.ReadLine()); int r = Fact(n); Console.WriteLine(n.ToString() + ! =  + r.ToString()); Console.ReadLine(); } or you can try this using System; using System.Collections.Generic; using System.Text; class Class2 { static int Factorial(int n) { if (n return 1; int result = 1; for (int i = 2; i { result = result * i; } return result; } static void Main(string[] args) { Console.Write(Enter a Number to find factorial: ); int n = Convert.ToInt32(Console.ReadLine()); int r = Factorial(n); Console.WriteLine(n.ToString() + ! =  + r.ToString()); Console.ReadLine(); } } }

Hi Try like this namespace Factorial { class Program { static void Main(string[] args) { Console.WriteLine( Give me the number you want the factorial: 
 ); long a = Convert.ToInt64(Console.ReadLine()); Console.WriteLine( The factorial of given number is:  + Factorial(a)); Console.ReadKey(); } public static long Factorial(long number) { if (number return 1; else return number * Factorial(number - 1); } } } Regards Iftikar
