Callback from Com Dll to CSharp method

[GE Security - Bob]

Hi,

Is this possible - to call a C# method from a COM Dll?

I wanted to send the COM dll the address of a C# function so I could call it
back. (This was originally written in C then C++).

Or, do I need to add events to the COM dll and C# can capture those?

Thanks!

Bob

If you have a COM component that accepts a function pointer for callbacks
then you can indeed use that from your managed code. I would suggest using a
pinned object just in case the garbage collector does its stuff before you
get your callback.
