class in managed c++ called from c#

Question

I have a class decalred inside managed c++ dll as

public class IPHelper
{
public:
    static void CheckIP(LPWSTR pSocketName);
    static void DebugMessage(const wchar_t *str, ...);
private:        
    static DWORD GetIPInformation(PSOCKET_RECORD &pInfo);
};

I compiled it successfully and add it as reference to my c# project. I am able to use the namespace, however the class seems empty and I'm unable to call the functions inside it.

Any ideas?

Answer 1

That class is not managed, it is native. You need to call it a public ref class if you want to use it from managed code.

Answer 2

You're going to need to invoke it using the P/Invoke method. See this reference for more information.
