Hmm, really? I hadn't seen that! I'm assuming you don't mean simple binary data base64 encoded in the email?
Right, the way to do it is pretty straightforward, it was the necessity that was hard to comprehend. Also, you do realize that ReadChar encodes? -----Original Message----- From: Unmoderated discussion of advanced .NET topics.

Not always. Email can by BinaryEncoded.. but that's more fyi... You are correct that I need the buffer to scan to the end of line sequences... hence the BinaryReader.ReadLine() question. ;-) I'm assuming someone has done it, if not, no big deal. Just was looking for any tips/tricks they might have done for their own buffering.
