Default Converting int to byte

Hi! I'm having same problems with this:

Code:
sendWholeMsg[1] = (byte)msgindex;
sendWholeMsg[2] = (byte)msgindex >> 8;
sendWholeMsg[3] = (byte)msgindex >> 16;
sendWholeMsg[4] = (byte)msgindex >> 24;
The error when I compile is as stated below:
Cannot implicitly convert type 'int' to 'byte'. An explicit conversion exists (are you missing a cast?)

I don't understand the error here, is there anything wrong with my codes?

Thanks!

Code:
(byte)msgindex >> 8
The above code is equivalent to the following (if you put in place implicit conversions that are taking place.

Code:
((int)(byte)msgindex) >> 8
The >> operators takes two integers, so the cast from msgindex to byte is then being cast again to an integer.

What you are probably trying to do is this:

Code:
(byte)(msgindex >> 8)
