I’m using an old technology called RTTY to send data (it’s basically fancy Morse Code) over radio.

RTTY can only transmit ascii characters

What I want to do is convert a file such as a small jpg or something similar into a block of ascii text, send the characters over radio, then convert the characters on the remote end back into the original file.

Some help getting started would be great.

I know I need to use StreamReader but then how can I convert the byte[] into an encoded ascii string that I can then ‘decode’.

    Basically, you want to use a Base64 conversion. It will inflate the size of the data, but it guarantees that you’ll be able to round-trip the original binary data.

    Use Convert.ToBase64String to convert a byte[] into a string, and Convert.FromBase64String to do the reverse.
