C++/CLI - Managed class to C# events

Question

I have a c++ class that triggers some method like an event.

class Blah {

   virtual void Event(EventArgs e);
}

How can I wrap it so whenever t

Answer 1

Create a class that inherits from blah and have it take a reference to your managed wrapper in the constructor. Override the Event() method and when it gets called you can just forward that method on to the managed wrapper class instance you are storing.

Note that you can't raise an event from outside of the containing class, so you'll have to either make it a plain delegate or call a helper method on the managed class to raise it for you.
