binary data through Socket

[mike w.]

I've got a tcpClient and a tcpListener talking over a socket.
How can I send binary data over the socket from one to the other?

I've got a .jpg in a BinaryReader and I need to send the bytes over the
socket to be rebuilt into a file on the other side.

thanks

Have you looked at TcpClient.GetStream...?

How does the GetStream know that the data is binary vs ascii?

Hi,

You instantiate a BinaryReader, passing it the Stream that you have opened.
The BinaryReader.ReadBytes method will return an array of Byte data.

if the file is big how do i handle sending chunks data instead of all at once?

Use the BinaryWriter. Assign only as much data to the BinaryWriter (array)
as you want to send at any one time (perhaps 511 bytes to match the default
packet size that is used by TCP/IP?). Then, add a delay between
assignments.

Well, that's what I'd do. Others may have some alternate approach.
