Everything Ken said is practically true; however, there are very complicated
ways of actually getting around this.
Technically, you can use techniques such as address space layout
randomization, jump tables, and so on which will virtually, 100%, fool
anything out there.
Some of the approaches are dangerously close to some of the research I'm
doing, so I can't talk about them, but it is technically possible to fool
every single decompiler out there.
Take care,
Sina

Sorry to say but no matter how much you would rather it not be possible it
is. It doesn't matter if you compile a c++ program or write something in
Asm. There are programs that can decompile code and some that do it rather
well. Remember though this is not a easy thing to do and if they are going
to use tools like this they can hack things by hand just the same.
You can do things like encrypt your data that helps but if a person is
determined enough they can break almost any security and uncompile almost
any language.
The best defense against someone hacking or copying your code. is either to
Open source it and put a good license on it or to charge a decent price for
it. You don't see people trying to rip companies off that sell their
product at a decent cost.

Hello,
I was wondering how you might obviscate code in .net. I know that there are
programs out there like reflector that will disassemble it for you and I'd
rather not have that happen.
