C++ to C# Wrapper

Kuba Florczyk

Hi

How to write method in wrapper for method from C++:

HRESULT Add(WCHAR *wcPath)

???

I've write something like this

int Add(string wcPath)

and it's doesn't work :(

regards

How about ...

public class MyWrapper
{
[DllImport("MyDll.dll", SetLastError=true, CharSet=CharSet.Auto)]
public static IntPtr Add(string wcPath);
}

Since, however, this is returning an HRESULT, is this method on a COM
object? If yse you must use COM Interop.

Hope this helps
