Hi, i would like to know, what is the best way to send files between python and C# and vice versa.

I have my own protocol which work on socket level, and i can send string and numbers in both ways. Loops works too. With this i can send pretty much anything, like package of users id, if it is simple data. But soon i will start sending whole files, maybe xml or executables.

Simple server with files is no an option because i want sending files from client too.

I was thinking about serialization but i don't know it is the best solution, but if it is i will love some tips from stackoverflow community.
