how can i protect my code from decompile ?

With third party obfuscators:

or found with Google :

Another solution is to write the (short) 'secret' code
in classic C++ and then use Managed C++ wrappers.

We offer a complete solution to protect your .NET source code from prying
eyes,

(1) salamander .NET decompiler, show how easy to get source code from the
..NET assemblies,
http://www.remotesoft.com/salamander/index.html

(2) obfuscator, make reverse engineering more difficult, the easiest to use,
support C#, VB.NET, J#, MC++, etc.
http://www.remotesoft.com/salamander/obfuscator.html

(3) protector, completely prevent disassembly (no more ildasm) and
decompilation, also offer string and resource protection,
http://www.remotesoft.com/salamander/protector.html

(4) native compiler, link and compile .NET executables to x86 native code,
run w/o .NET framework, coming soon,

The problem then becomes the link between the managed and unmanaged
code. Doing this just makes it easier for an attacker to isolate the
critical code, then bypass it completely.

Hello,

Using a commercial obfuscator, encrypted loader is a good start
(see response to "Licence Key generator", a few posts up). However
depending on the apps and the attack you are trying to prevent, you
might want to consider doing a lot of "custom" anti-reverse
engineering or anti-cracking code.

I think the idea was that the 'secret' code also does the work
(proprietary algorithm, whatever), so bypassing it definitely doesn't
help in understanding its secrets.

Dear Daylor,

I am well aware of the problem you are describing in your letter.
I suggest you to take a look at CliSecure product, an encryption base tool that helps proctet .net apps from being tampered.

You can find it here: http://www.secureteam.net
