Question

I’m having trouble with this one problem. I’m trying to compare Color RGB in a list
and sort them by there RGB. I’ve thought about adding it to a dictionary but don’t know exactly how to get the values of the colors once their added to the Dictionary. So how would can I get the RBG of color in a list to compare them with one another. Any help or advice and I will be grateful, thanks.

Answer 1

You can easily use System.Drawing.Color structure for this.
It provides an toArgb method which you can use to get the equivalent integer value of a color.

List<Color> lc = new List<Color>();
Color c = new Color();
c.R = 0xFF;
c.G = 0x00;
c.B = 0x00;
lc.Add(c);
...
...
lc.Sort((c1, c2) => c1.ToArgb().CompareTo(c2.ToArgb));
