Question

I have a C# .dll that interfaces with the API of a large external progam.

That program expects an entry point function in the dll with the form:

extern void entrypoint(
char * a,
int * b,
int c);

It doesn’t find this and complains.

The original/default entry point for my dll is just:

public static void Main(string[] args)

I’ve tried creating a function like

public static void entrypoint(char a, int b, int c)

But it’s obviously not that simple. I’ve seen a bunch of stuff about how to do this in C++ with __declspec(dllexport), and I’ve seen a few complex/hacky solutions for C#, but it seems like there ought to be a straightforward way to do it. Any ideas?

Answer 1

If your external system is COM based, there are ways to do this, as .NET is a COM object under the covers.
