C# Convert Color to argb

Question

How to convert Color to argb as array int

pseudo example

Color color=nw.GetPixel(i, j);
int[] argbarray = color.toARGBArray();

result:
argbarray[0]=255  (alpha)
argbarray[1]=241  (red)
argbarray[2]=128  (green)
argbarray[3]=69   (blue)

those are already available as properties: `color.A, color.R...` — Ňɏssa Pøngjǣrdenlarp, Mar 28 '15 at 23:32
if you are talking to me, I didnt "put a minus" I did answer,,,except for the array part (that is left for the student) — Ňɏssa Pøngjǣrdenlarp, Mar 28 '15 at 23:33
@Plutonix, I have never found such that you write, and I was looking for a very long and hard — user2812337, Mar 28 '15 at 23:35
Open Object browser; search for color - it will be under System.Drawing. Examine the properties there; or on MSDN or look at the list that intellisense offers. You'd have to work hard to miss them — Ňɏssa Pøngjǣrdenlarp, Mar 28 '15 at 23:37
I searched through Google, he did not give the sense of anything that I needed — user2812337, Mar 28 '15 at 23:40
`Color c = Color.Red;` then type `c.` Intellisense will open up a list of the props and methods related to Color - *right there at the top* are `A, B` and `G`. You'd have to work to avoid them — Ňɏssa Pøngjǣrdenlarp, Mar 28 '15 at 23:59

I searched through Google, he did not give the sense of anything that I needed

I googled C# color bytes and this is the first result Convert color to byte value

still no sense?

BTW: My way would be:

Color color = Color.FromArgb(1,2,3,4);  //alpha,red, green, blue
var argbarray = BitConverter.GetBytes(color.ToArgb())
                .Reverse()
                .ToArray();

argbarray[0]=1  (alpha)
argbarray[1]=2  (red)
argbarray[2]=3  (green)
argbarray[3]=4  (blue)

My queries are different from the above "I googled C# color bytes and this is the first result Convert color to byte value" – user2812337 Mar 28 '15 at 23:57
@user2812337 than explain it. I see no difference. Above code does exactly what you expect from `toARGBArray` in your pseudo code – EZI Mar 28 '15 at 23:58
now I'll know, and other users will find this answer – user2812337 Mar 28 '15 at 23:58

@user2812337 What should I understand from your comments? *"I am so ignorant that I can even understand a correct answer posted"* ? – EZI Mar 29 '15 at 00:03
no I meant that my inquiries in Google were incorrect – user2812337 Mar 29 '15 at 00:09
