method call error

I'm getting
"Error 1 An object reference is required for the non-static field, method, or property 'JWGenetics.Genetics.program()' e:\visual studio 2010\Projects\JWGenetics.cs 50 13 JW Genetics"

on method program.
How do I fix this? I do not want to be passing arg/param.

Code:

using System;
using System.IO;
using System.Collections.Generic;
using System.Linq;
using System.Text;

"program" is not static. You need either an instance of your class to call program on, or make program static.

Thanks for the tip on instance.

I solved it by putting "Main" into a separate class and called "program" from it there.
This allowed me to access all the other methods.
