How to create a simple FTP server and client for it?

Question

Computer networks

Good day, people, can you tell me how to create a simple ftp server only for uploading files to it, without reading, downloading, etc. The client program must generate files and send them via the ftp protocol to the server part of the program, which should already receive, calculate and display statistics, the problem is only with sending and receiving. Can you give me more details on how to implement this in c#? (you can also use c++, but c# is better) Thanks in advance.

Answer 1

Probably a simple FTP server (TFTP) will suit you.
There are many sample implementations on the net:

Answer 2

to open the description of the ftp standard, and to implement. or recycle, throw out what you do not need and implement the rest.
or just formulate the TOR and implement it.
Or go to freelancing, and there find someone who will do it for you.
