Solution 1

The short answer is "You can't."

The longer answer is:

You can make it difficult, but even then, not exactly very. Google for ".net Obfuscator" and you will find a wealth of info.

(Even with native code, you can't fully protect it from a determined de-coder who can disassemble your binary to ASM or C)

As Griff said, you can't. You can spend a small fortune on software to make it more difficult but it's never 100% effective.

If you have some super-duper, fancy-wancy code sections that you really need to protect, recode those parts as functions in a C++ (not CLR) dll and call those from your .NET program to use it. That's about the best you can do to make it harder but still not impossible.

Solution 3

Use an obfuscator to protect against decompilers. See Crypto Obfuscator.
