What's wrong with this expression? Cannot implicitly convert type 'int' to 'byte'

Question

I am getting the error \"Cannot implicitly convert type \'int\' to \'byte\'. An explicit conversion exists (are you missing a cast?)\". Doesn\'t byte + byte = byte

Answer 1

C# widens all operands to int before doing arithmetic on them. So you'll need to cast it back to byte explicitly.
