C# Question

I know how to calculate factorial using a loop. Below is the code for loop but I am getting error while doing it by recursion, below are both the codes can somebody sugg

`namespace factorial`

{

class Program

{

static void Main(string[] args)

{

int i, number, fact;

Console.WriteLine("Enter the Number");

number = int.Parse(Console.ReadLine());

fact = number;

for (i = number - 1; i >= 1; i--)

{

fact = fact * i;

}

Console.WriteLine("\nFactorial of Given Number is: "+fact);

Console.ReadLine();

}

}

}

Factorial using Recursion :

est something as where I am going wrong? When I am calculating it using recursion?

Factorial using loop:

`public double factorial_Recursion(int number)`

{

if (number == 1)

return 1;

else

return number * factorial_recursion(number - 1);

}

public double factorial_WhileLoop(int number)

{

double result = 1;

while (number != 1)

{

result = result * number;

}

return result;

}

your call name is not equal to you method name.

```
factorial_Recursion is the method name.
factorial_recursion is the call
