  • 0

I have a binary file. It consists of 4 messages, each is inthe size of 100 bytes.
I want to read that last 2 messages again. I am using BinaryReader object.
I seek to psosition 200 and then I read: BinaryReaderObject.read(charBuffer, 0, 10000),
where charBuffer is big enougth.
I get all the time the a mount of read is always missing 1. Instead of getting 200 I get 199. Instead of getting 400 I get 399.
I checked and saw the size of the file is correct and the data that I get starts at the right place.

Thnaks,

    The problem was that I used a wrapper to BinaryReader object.
    When calling the Read method there are some function overloding. Instead os using the signeture of char[], I used byte[]. Till now it worked fine because there was only use of utf-8, but now when I entered real binary data in the beginning of each message it caused the problem.
