Hi,

Can someone please help me convert my C structure/function into C#? I really need this badly...
I believe I can call the DLL properly if I have able to correctly convert the function and marshal properly my structure.

Here is my struct and the function that uses it:

Code:

typedef struct UIclient_info {
	char name[50];
	int age;
	SECONDUSER *stParent;
} FIRSTUSER;

What's marshalling? I've had to use it extensively for a project but I don't
know what it means. I tried to look for a definition in the Internet but I
couldn't find anything that would explain what it is.
Is converting a C-style struct to a C# class (or struct) marshalling? And
what about the function exports? Are those Marshalling too?

Thanks for your help and thanks for helping me with the Dll exports (the...
