public variables and scope in C#

Question

It is my understanding that a public variable declared at the class level of a program was available everywhere else in the program.

In the following code:

namespace Lab13
{
    class Program
    {
       int lower = int.Parse(Console.ReadLine());


        static void Main(string[] args)
        {
            Console.Write("Enter a lower bound number:");


            lower = int.Parse(Console.ReadLine());
        }
    }
}

I get a compile error with regards to my assignment of lower.

Put 'public' in front of variable declaration. Class also need to be public. — jdweng, Jan 17 '17 at 21:28
The issue with your code is static/instance; nothing to do with public/private — BradleyDotNET, Jan 17 '17 at 21:29
What does the error say exactly? It might hint something about instance variables (it needs to be static) — Don Cheadle, Jan 17 '17 at 21:30

It's an instance field, and instance members couldn't be accessed from static members.

Since I see that it's just a sample code, changing int lower to static int lower will be sufficient to access the whole field from Main method.
