WebApr 28, 2004 · I always understood the checksum to be the 2's complement of the sum of the bytes. Therefore the checksum is actually different than just the sum of the bytes. If you just want the sum of the bytes NigelQ's code is correct. If you want the checksum, NigelQ's code would need to be modified to take the bitwise complement of the sum and then add 1. http://www.slavasoft.com/fastcrc/samples/cs_net_sample_checksum_crc32_file.htm makerhealthcare
