Question

I have a project in MS Visual Studio 2008 Pro. I’m new to the environment and the language, so forgive a noobish question.

I have a type ControlCode:

namespace ShipAILab
{
    public abstract class ControlUnit {

        public enum ControlCode {
            NoAction = 0x00, 
            MoveLeft = 0x01,
            MoveUp = 0x02,
            MoveRight = 0x04,
            MoveDown = 0x08,
            Fire = 0x10,
        }

    }
}

I want this to be accessible from another class, BoardUtils, which is in the same ShipAILab namespace:

    public static IList<ControlUnit.ControlCode> pathToPoint(IDictionary<CompPoint, int> dist, CompPoint destination) {
          ControlUnit.ControlCode code = ControlUnit.ControlCode.MoveLeft; // works
          ControlCode c2 = ControlCode.MoveDown; // how do I get this to work?
    }

Why doesn’t this work automatically, by virtue of sharing a namespace? Do I need a using statement? Can I “typedef” it like in C to rename ControlUnit.ControlCode to something more concise?

Answer 1

Your enumeration is inside the ControlUnit class.

If you want it to be accessible without typing the class name, move the enumeration outside the class.
