Alternative to BitConverter.ToInt32
- by MusiGenesis
I'm using BitConverter.ToInt32 to pack 3 byte values into an int, like so:
byte R = 0;
byte G = 0;
byte B = 0;
int i = BitConverter.ToInt32(new byte[] { R, G, B, 0 }, 0);
Is there a faster way to do this that doesn't involve the creation of a new int each time? Getting the bytes out of an int is easy:
int i = 34234;
byte B = (byte)(i >> 0);
byte G = (byte)(i >> 8);
byte R = (byte)(i >> 16);
Is there a simple way to reverse this process and use bit-shifting to write the RGB bytes back over an existing int?
