How do I assign an event handler to an event in C++/CLI?

Question

How do I add "events" to an "event"/delegate? What is the syntax? Is it the same in C++/CLI and in C#?

Answer 1

1: If underlyng delgate of the event is a custom one you define yourself that is a class memeber (example from MSDN):

delegate void Del(int, float);
ref class EventReceiver {
public:
    void Handler(int i , float f) {  }
};
myEventSource->MyEvent += gcnew Del(myEventReceiver, &EventReceiver::Handler);

2: If the underlying delegate is a global handler and has the standard signature for .NET events (object + event args) (from DPD answer):

delegate void MyOwnEventHandler(Object^ sender, EventArgs^ e) { }  
myEventSource->MyEvent += gcnew EventHandler(MyOwnEventHandler);  

3: If the underlying delegate has the standard signature for .NET events and the event handler is a class method:

ref class EventReceiver {
public:
   void Handler(Object^ sender, EventArgs^ e) {  }
};
myEventSource->MyEvent += gcnew EventHandler(myEventReceiver, &EventReceiver::Handler);

4: Using System::EventHandler generic (that takes a MyEventArgs args parameter) as the underlying delegate:

ref class EventReceiver {
public:
   void Handler(Object^ sender, MyEventArgs^ e) {  }
};
myEventSource->MyEvent += gcnew EventHandler<MyEventArgs^>(this, &EventReceiver::DataReceived);
