Convert color to byte value

Question

In C#, how can I convert a Color object into a byte value?

For example, the color #FFF would be converted to the value 255

Answer 1

Try this,

string colorcode = "#FFFFFF00";
int argb = Int32.Parse(colorcode.Replace("#", ""), NumberStyles.HexNumber);
Color clr = Color.FromArgb(argb);

Answer 2

You could use the ColorTranslator.FromHtml function:

Color color = ColorTranslator.FromHtml("#FFF");

Answer 3

You can get the byte values of a .NET Color object with:

byte red = color.R;
byte green = color.G;
byte blue = color.B;

That gives you 3 bytes. I don't know how you expect to get a single byte value. Colors are (AFAIK) almost never represented by single bytes.

Answer 4

You can use ConvertFromString() method from ColorConverter class.

Attempts to convert a string to a Color.

Return Value
Type: System.Object
A Color that represents the converted text.

ColorConverter c = new ColorConverter();
Color color = (Color)c.ConvertFromString("#FFF");
Console.WriteLine(color.Name);
