C#是否可以在外部布尔值中使用在main()中声明的整型？

using System;

class Program
{
    static void Main()
    {
        int number = 10;
        bool isNumberPositive = (number > 0);

        Console.WriteLine("Is the number positive? " + isNumberPositive);
        OtherMethod(isNumberPositive);
    }

    static void OtherMethod(bool isPositive)
    {
        if (isPositive)
        {
            Console.WriteLine("The number is positive.");
        }
        else
        {
            Console.WriteLine("The number is not positive.");
        }
    }
}
