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.

Did you not find [this](http://stackoverflow.com/q/982028/1945651) when you Googled? It's the first match when I search for "convert html color to .net color". — JLRishe, Jan 30 '13 at 10:31
The below answers suggesting ColorConverter.ConvertFromString() may be preferable though. — JLRishe, Jan 30 '13 at 10:34
I have a color variable in c# and i want it to be converted to bytes value. and thank you for negative points i wont post more question here. — Wajahat Kareem, Jan 30 '13 at 10:35
What color system are you using where colors are represented by a single 8-bit value? I'm not one of the people who downvoted you BTW. — JLRishe, Jan 30 '13 at 10:35
If you want the byte values of the colors, you need only access `color.R`, `color.G`, and `color.B`. This will give you three bytes, though, not just one. — JLRishe, Jan 30 '13 at 10:39

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.

You could use the ColorTranslator.FromHtml function:

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

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);

Try this,

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