[Guest]

Hi
When I read from a file through a binaryReader, how can I know when the end
of the file is reached?
thanks

That depends on how you're reading it - what exactly are you doing with
it? (Also, do you definitely need a BinaryReader? I've seen a lot of
people using them when they really only need a stream. Just a thought.)

I want to read bytes from a file to send them over the internet to another
computer.

I would just use the NetworkStream stream or the socket directly and read
until bytesToRead is read or 0 is returned from read(). You should send the
len first or in some fixed len header so you know how many bytes are coming.
Another good reason for this information upfront is you may want to reject
the request for a 3+GB upload or for some other reasons (i.e. no space,
wrong name, wrong secret, etc).

The doco is pretty good on it. Lookup NetworkStream class in msdn.
