Simple example of array accessor using enums

MessageType.cs

public class MessageType {
    public string[] array;
    public enum MessageEnum {
        Shutdown = 0,
        Reboot = 1,
        Softlock = 2
    }
    public string this[MessageEnum val] {
        get {
            return array[(int)val];
        }
        set {
            array[(int)val] = value;
        }
    }
}
