Color from my own Enum

Question

I have an enum

private enum EventColors
            {
                Aquamarine,
                Azure,
                BurlyWood,
                CadetBlue,
                Gainsboro,
                Gold,
                Gray,
                Khaki,
                LawnGreen,
                LightGreen,
                LightSkyBlue,
                Linen,
                MediumOrchid,
                MediumPurple,
                MistyRose,
                Olive,
                OliveDrab,
                Orange,
                OrangeRed,
                Orchid,
                PaleTurquoise,
                Peru,
                Pink,
                Plum,
                RoyalBlue,
                SandyBrown,
                SeaGreen,
                SteelBlue,
            };

I chose the best from System.Drawing.Color and I would like to randomly choose one:

Array values = Enum.GetValues(typeof(EventColors));
                Random rnd = new Random();
                EventColors randomBar = (EventColors)values.GetValue(rnd.Next(values.Length));

How can I convert random chosen color from my enum to System.Drawing.Color. ? Is this possible without using switch?

Answer 1

You can create Dictionary<EventColors, System.Drawing.Color>, fill it by this way:

Dictionary<EventColors, System.Drawing.Color> colors = new Dictionary<EventColors, System.Drawing.Color>();

colors.Add(EventColors.Aquamarine, System.Drawing.Color.Aquamarine);
colors.Add(EventColors.Azure, System.Drawing.Color.Azure);
//... other colors

and then:

Array values = Enum.GetValues(typeof(EventColors));
Random rnd = new Random();
EventColors randomBar = (EventColors)values.GetValue(rnd.Next(values.Length));

System.Drawing.Color someColor = colors[randomBar];

OR

You can use reflection:

Array values = Enum.GetValues(typeof(EventColors));
Random rnd = new Random();
EventColors randomBar = (EventColors)values.GetValue(rnd.Next(values.Length));

string name = Enum.GetName(typeof(EventColors), randomBar);
var type = typeof(System.Drawing.Color);
System.Drawing.Color systemDrawingColor = (System.Drawing.Color)type.GetProperty(name).GetValue(null);
