How to get invocation list of an explicit event in C# -

i can define event following:

public event msg_callback event_pingmessage;  

and invocation list of event following:

multicastdelegate event_delegate = (multicastdelegate)this.gettype().getfield(event_name,                                 bindingflags.instance | bindingflags.nonpublic | bindingflags.getfield).getvalue(this);  foreach (var handler in event_delegate.getinvocationlist()) {     // use handler() here  } 

but, if define event_pingmessage explicit event, like:

    private msg_callback explicitevent;     public event msg_callback event_pingmessage     {         add         {             explicitevent += value;             int = 0;           }         remove         {             explicitevent -= value;         }     } 

the multicastdelegate event_delegate = ... line throws exception:

object reference not set instance of object. 

how can .getinvocationlist() explicit events?

you can use explicitevent.getinvocationlist(). explicitevent equivalent of field returned getfield(...) call field-like event.
