try this one:

using System;
using System.Collections.Generic;
using System.Text;
class Class2
{
    static int Fact(int n)
    {
        if (n <= 1)
            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 <= 1)
            return 1;
        int result = 1;
        for (int i = 2; i <= n; 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: \n ");
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 <= 1)
return 1;
else
return number * Factorial(number - 1);
}
}
}

Regards,
Iftikar
