Using an obfuscator tool is the only way. Be aware that obfuscating doesn't make it "impossible", but it can make it significantly more difficult to do in a timely manner. One tool not to bother with is the one that comes with Visual Studio. It doesn't do *nearly* enough.

Standing with the European law, you shouldn't.
Revere engineering is a right of a user if it wants to know how a thing works, to develop other things that interoperate with it.

It is not in the right of a user reverse it to reuse it to make its own money without giving the original developer the proper credits. But that's not a problem of R.E.: it is a problem of fraud!

You are also entitled to obfuscate if you wish.

Use an obfuscator like Crypto Obfuscator. An obfuscator converts your code and symbols into senseless data while retaining the logic.
