Question

I have this Enum:

enum ASCIIChars
        {
            BLACK = "@",
            CHARCOAL = "#",
            DARKGRAY = "8",
            MEDIUMGRAY = "&",
            MEDIUM = "o",
            GRAY = ":",
            SLATEGRAY = "*",
            LIGHTGRAY = ".",
            WHITE = " "
        };

Here is where I am using it:

private void GetShadeColor(int redValue)
        {
            string ASCII = " ";

            if (redValue >= 230)
            {
                ASCII = ASCIIChars.WHITE;
            }
            else if (redValue >= 200)
            {
                ASCII = ASCIIChars.LIGHTGRAY;
            }
            else if (redValue >= 180)
            {
                ASCII = ASCIIChars.SLATEGRAY;
            }
            else if (redValue >= 160)
            {
                ASCII = ASCIIChars.GRAY;
            }
            else if (redValue >= 130)
            {
                ASCII = ASCIIChars.MEDIUM;
            }
            else if (redValue >= 100)
            {
                ASCII = ASCIIChars.MEDIUMGRAY;
            }
            else if (redValue >= 70)
            {
                ASCII = ASCIIChars.DARKGRAY;
            }
            else if (redValue >= 50)
            {
                ASCII = ASCIIChars.CHARCOAL;
            }                       
            else
            {
                ASCII = ASCIIChars.BLACK;
            }

            ASCIIArt.Append(ASCII);
        }

I’m getting the following errors in the enum declaration:

Cannot implicitly convert string to int.

Answer 1

Yeah, you can’t do that. Enum values are numeric-only. Consider defining a static structure mapping enum values to string/char values, or changing your enum to a class with a predefined static instance corresponding to each enum value.
