• hi can someone help me with the negative integer conversion to bytes array? something to do with two's compliment.. i have no background in this area, having been an office automation programer all the time. the bitconverter.getbytes does not seem to cut it.

What do you expect you to get? What are you getting? There's multiple ways to represent negatives in binary.

[vivid scarab]

the number to be converted to a byte array is Int16.Minvalue - 1.
after replacing the element at [0] with 252 (256 - size of Int16) the expected
value is [252, 255, 127, 255, 255, ...]

what i get is [252, 1, 128, 0, 0, ...]

i am using the BitConverter.GetBytes on the number.

what i would like to know are the steps by which the number gets converted to the expected result..

What language?

There's ones complement and twos complement

i checked internet and was told that the bitconverter returns a valid two''s compliment array of bytes. but the exercise does not seem to think so. obviously i am doing something wrong in between. can't figure out what.. will go thru your link. thanks issac.
