I can help you with this but I need to be more clear about what you are doing. Also, a shameless plug but my chapter in the Wrox book below has a lot of info on mixing managed and unmanaged code, and has a step by step wrapping example. FWIW.
Now, right, you say creating a "Managed DLL wrapper for a DLL (c-style)." As Jim pointed out, code that exists in a DLL, P/Invoke is the Interop method of choice. Is this your case - you already have an existing DLL of code that you want to call? (This is also covered in the chapter) If you have existing C++ code, that you want to have Interop with other managed code, then the Interop technique is to write a managed __gc wrapper class around the C++ code. There are some gotchas that you need to pay attention to that are beyond the scope of this email. >assembly(viewed with ILDASM) have my namespace and the ‘std’ namespace >and a lot of strange definitions, like the functions in the C DLL.
