C＃在运行时将只读变量添加到类中

Question

I'm trying to find a way to add colors to a "palette". The worst part of not learning computer science is that it is hard to word questions. I've been searching for adding enumerations in a class during run time. Because ideally, I can do a Console.ReadLine() to add a new color.

class Program
{
    static void Main(string[] args)
    {
        Color _Color = new Color();

        Console.WriteLine(Palette.Black);
        // _Color.addColor(Console.ReadLine(), Console.ReadLine());
        Console.ReadKey();
    }
}

public class Palette
{
    private readonly string color;
    public static readonly Palette Black = new Palette("black");
    public static readonly Palette Red = new Palette("red");
    public static readonly Palette Green = new Palette("green");
    public static readonly Palette Blue = new Palette("blue");

    //I want to be able to create new colors by using the Color.addColor() method

    private Palette(string inputColor) { this.color = inputColor; }
    public override string ToString() { return this.color; }
}

public class Color
{
    public void addColor(string colorName, string color) 
    {
        //create a new color into Palette using form:
        // public static readonly Palette colorName = new Palette("color");
    }
}

I want to be able to do Console.WriteLine(Palette.Yellow) after inputting into the Console that I want to add the color yellow into the palette.

Answer 1

I think you should start with maybe redesigning your application to use a collection of colors instead of fields on palette. However you might be able to achieve what you're looking for with ExpandoObject . I found it from a different article here .

C# is not designed in a way for you to dynamically create variables. Like @skalpin said, a redesign in pretty much the only solution for you.
