c# - Interface from a C DLL to .NET -

I have a legacy DLL which is written in C. I want to call from the NET application. The problem is that the DLL interface for C DLL is quite complex. This is something like this:

  __Dllexport Zero __stdcall ProcessChunk (Zero * p_prochdl, const BIG_INPUT_STRC * p_inparams, BIG_OUTPUT_STRC * p_outparams);  

BIG_INPUT_STRC / BIG_OUTPUT_STRC contains all kinds of things ... hints for buffer arrays, enumerated criteria, integer parameters, etc. In essence, they are complicated.

The first question: Is there an easy way to get all the structure information contained in the DLL header file in the C # class, or do you literally copy and paste everything in C # and redefine it? need to? It seems redundant.

What is the correct way to pass strokes from unmanaged DLL to C #?

Finally, how do the buffer arrays correctly pass in C # from unmanaged DLL? Alternatively, how do I cross a two-dimensional array in DLL?

Thanks, -Greg

Its direct effect is P / Invoke in C # Using C #.

I believe that you have to define data structures manually in C #.

I will take care of this topic
