Factorial program in c#...

The factorial is normally used in Combinations and Permutations (mathematics).

```
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication28
{
    class Program
    {
        static void Main(string[] args)
        {
            int i, fact = 1, number;
            Console.Write(" Enter any Number: ");
            number = int.Parse(Console.ReadLine());
            for (i = 1; i <= number; i++)
            {
                fact = fact * i;
            }
            Console.Write("\n Factorial of " + number + " is: " + fact);
            Console.WriteLine("\n");
        }
    }
}
```
