How to test if a delegate or event is empty

[RFOG]

In C# is very easy:

if(myDelegate== null)
//Install it.

but in C++/CLI that does not work:

if(myDelegate== nullptr)
//Install it.

gives:

Error C3918:usage requires 'member' to be a data member

But myDelegate has operator == overloaded. I don't understand why it fails.
If I try some like this:

myDelegate->GetInvocationL ist()->Length==0

I get same error.

And other variations.

Use a custom event, like this:

private:

//! \brief MulticastDelega te chain of event handlers for the \ref Closed
event.

System::EventHa ndler^ CloseHandlers;

public:

virtual event System::EventHa ndler^ Closed

{

void add( System::EventHa ndler^ handler )

{

CloseHandlers += handler;

}

void remove( System::EventHa ndler^ handler )

{

CloseHandlers += handler;

}

}
