Create and exercise a factorial method that has no error checks at all. using C# dotnet

 class afctorial4  
   {  
     public static void Main(string[] args)  
     {  
       for (int i = 6; i > -6; i--)  
       {  
         Console.WriteLine("i = {0}, factorial = {1}", i, MyMathFunctions.Factorial(i));  
         Console.ReadLine();  
       }  
     }  
   }  
   public static class MyMathFunctions1  
   {  
     public static double Factorial(double value)  
     {  
       double factorial = 1.0;  
       do  
       {  
         factorial *= value;  
         value -= 1.0;  
       } while (value > 1);  
       return factorial;  
     }  
   }
