1. How can I protect my code inside the .dll assembly (MSIL) from being decompiled and visible? there are some softwares out there that can reverse engineer a compiled .dll into a good source code.

Compilers that target the CLR ALL produce Intermediate Language, or IL. This - like Java bytecode - allows the system to JIT the IL to native code and execute it, so that it can be run on any OS (Microsoft's problem with .NET is that it relies too much on native OS resources, but it does provide a consistent UI). The Microsoft .NET Framework SDK even comes with a disassembler, ildasm.exe. For those of us who can read IL, we don't even need decompilers like .NET Reflector[^] (though it is nice at times!). There are just as many problems that can output this source code as well, although I have yet to see one that does an impeckable job with more advanced source code (using all the tricks of the languages).

All you can do - which is true of any program in any language - is make it hard and, therefore, costly to do so. I remember the words of Bruce Schneier with questions like these, who basically says that anything is crackable - it's just a question about the cost of resources to do so.

Make your program work well and hide your important code in complexity, or write native DLLs and P/Invoke or interop (use COM to make this easy) the functions and components in those native DLLs. Keep in mind, though, that they too can be decompiled (though decompiling C/C++ libs is more difficult, more expensive, and less correct than with IL and bytecode).

You can get obfuscators to obfuscate private members, but for every obfuscator there is a de-obfuscator (and they've really never stopped me - and I'm sure others - anyway, from seeing how something is done for academic reasons).
