How to convert a byte array to an int?

Using exactly i < bytes.Length as upper bound of the loop allows the JITter to eliminate bounds checks on bytes [i], so I chose that variant. Making b an int allows unnecessary conversions from and to byte. If you want more flexibility than BitConverter, but don’t want those clunky 1990s-style explicit loops, then you can do:
