How to get source code from native dll?

Question

How can i get source code from native dll ? With Reflector no luck.

Answer 1

You cannot.

Strictly speaking, you also cannot get the source code of a managed dll with Reflector (e.g. there are no comments; and if it's been obfucated you also will not see the source code). The .NET Reflector is just very good at disassembling the MSIL code.

You can disassemble a native dll, you just won't like it. For example, i am trying to debug a crash in code that isn't mine:

20C46DB7  |.^ 73 EC         |\JAE SHORT 20C46DA5

But source code? No.
