Reference variable from a different method, class, file

Question

I need to reference the value of a variable in a different method, class, and file than the one I am currently in. I am brand new to C# and still trying to get these concepts.

Answer 1

In your case, you can set that variable as return parameter of your method:

namespace Planning
{
    public class Service
    {
        public bool AddRoute()
        { 
            bool variable = true;
            return variable;
        }
    }
}

Call from different class:

namespace Planning
{
    public class AnotherClass
    {
        public void DoSomething()
        {
            Service service = new Service();
            bool otherVariable = service.AddRoute();
        }
    }
}

Now value of your variable from AddRoute method is inside otherVariable in another class.
