ActiveX, TOR and .Net

Hi Everyone,
I need to use persistence from .Net (C#) to a Natural (OS/390) server.
Has anyone have any examples of invoking either TOR files or the ActiveX from C#?
I can use the ActiveX but need more info on the SetSendData and how to populate it for example from a structure.

Most of the examples are for VB only.

EntireX 7.1.1 PL60 on Windows 2000.

Kind Regards
