问题 I have a ARGB value stored as an int type. It was stored by calling ToArgb. I now want the byte values of the individual color channels from the int value. for example int mycolor = -16744448; byte r,g,b,a; GetBytesFromColor(mycolor,out a, out r, out g, out b); How would you implement GetBytesFromColor?
