String to Binary in C#

This is a Rosetta Code post.

Story

I was tinkering with Assembly Code the other day and had a brain fart which resulted in this post!

If you have a literal string like Not my monkey how can this be converted to binary (for reasons), does that binary have to be 8 bit bytes and what would the padding logic look like?

Task

Given the string Not my monkey convert it to binary and then back again to text.

Solutions

baz
