IsPrimeNumber() function

This is very simple code rather than writing complex code
whch we were used to write during our colllage days :)

public static bool IsPrimeNumber(int number)
        {
            if (number == 0 || number == 1)
                return false;

            if (number == 2 || number == 3)
                return true;

            int square = number * number;

            if (square % 24 == 1 )
                return true;

            return false;
        }
