EventHandler is just a delegate--which provides the functinality of an object-oriented function pointer. If you want to delegate to the same method using the same delegate allocation, there's no problem with that. The only state kept by the delegate is the method to call; the rest of the state is passed upon invocation.
GC will deal with de-allocation when both references are not needed anymore. http://www.peterRitchie.com/ On Tue, 12 Jul 2005 10:59:42 +0100, Andrew Marshall <[EMAIL PROTECTED]> wrote: >Hi all, > >Say I have two objects capable of sending events, and an event handler. > >I could do this... >1. >//////////////////////////////////////////////////////////////// > >public void objectHandler( object sender, EventArgs args ) >{ > ...do some stuff... >} > >{ > ... > object1.myevent += new EventHandler( objectHandler ); > object2.myevent += new EventHandler( objectHandler ); > ... >} > >or this... >2. >/////////////////////////////////////////////////////////////////// > >public void objectHandler( object sender, EventArgs args ) >{ > ...do some stuff with sender... >} > >{ > ... > EventHandler myEventHandler = new EventHandler( objectHandler ); > object1.myevent += myEventHandler > object2.myevent += myEventHandler > ... >} > >///////////////////////////////////////////////////////////////////////// > >Is there any difference? 2.
