stop reflection

Is there a simple way to prevent people from using a tool such as Reflector to disassembled .NET assemblies?

In our code, we use reflection sometimes to invoke methods of our own assemblies, and this we'd like to permit from within our own assemblies. But as for other people using tools, is there a way to prevent them from peeking at the code?

Thanks

As far as I know, obfuscation is the only means of preventing reverse engineering.

Check out this utility from Microsoft, it should help you out.  I personally have not tried it.

Another hardcore method would be to encrypt your DLL assemblies and load them via some kind of decrypting stream and then use reflection :D. Oh, you need to store the key to decrypt the file, so this method sucks. Or you can use an USB token with own memory to store the key... What do you want to protect?

Thanks.

What do I want to protect? Just to prevent reverse engineering.
