Get Factorial of number:-

public static int PrintFactorialOfNumber(int number)

{

// 7*6

int result = 1;

for (int i = number; i > 0; i--)

{

result = result * i;

}

return result;

}

Calling above method:

static void Main( string [] args)

{

int factorial;

factorial = clsfactorial.PrintFactorialOfNumber(5);

Console.WriteLine("Factorial Of 5 Is " + factorial.ToString());

factorial = clsfactorial.PrintFactorialOfNumber\(7\);  

Console.WriteLine\("Factorial Of 7 Is " + factorial.ToString\(\)\);  

Console.ReadLine\(\);  

}

Output
