[rzvme]

I need to be able to get every bit from a file (0 and 1). How do i do this. please help

You could try reading all the bytes and then convert this to bits.

and how exactly do i do this

Take a look at the BinaryReader (read data from the file) and BitArray (access the data bit-wise).

i tried with that but it retrives bytes (in ascii)

I know. That's why I also pointed you to the BitArray class.

You can use the && operator to pull out each bit. myByte && 1 myByte && 2 myByte && 4 etc

ASCII has nothing to do with it. It returns the bytes in whatever format they are on the hard drive.

i don't want bytes i want bits(0 and 1)

how exactly do i use this??

Nothing reads bits. You need to take each byte and strip off the bits to get the bit you want. If your value is 10001101, then 10001101 & 1 = 1, 10001101 & 10 = 0, 10001101 & 100 = 1, etc.

I know that, although I don't see why. My point is that what you said is wrong, ASCII has nothing to do with it.
