How to convert word to binary code?

Question

C++ / C#

I am engaged in the creation of an encoder, there were problems.
You need to do the following: read the contents of the file, convert everything to binary code, and then encrypt it. I wanted to convert everything to ASCII first and then to binary. But how to do that? Is it necessary to parse a site with ASCII?

Answer 1

I wanted to convert everything to ASCII first

What for? What is the original encoding? It can go astray if converted to ASCII. We translate all characters into a binary number and forward.
