Again on FTP trasmission (dotNET mode)

Here below a private methods of an ad-hoc class for trasmit data.
In other sources you’ll find the trasmission using a stream reader with string codification (UTF, ASCII and so on). The below adapt the procedure using a binary stream (example for trasmit PDF file or ZIP).
Consider very important to cle the binary stream in reading if, after the trasmission, you need to manage the original source (example : move file in a folder backup).
