C#

<pre lang="cs">    OnEvent += new EventHandler(HandlerMethod);</pre>So I would assume that to unsubscribe you would do the reverse:<br />
<code lang="cs"><pre lang="cs">    OnEvent -= handleToEventHandlerObject;</pre>However since this the EventHandler was created anonymously you do not have a handle/reference to it.  <br />
<br />
So my next assumption would be this:<br />
<code lang="cs"><pre lang="cs">	EventHandler handleToEventHandler = new EventHandler(HandlerMethod);
		
	/ ... /
 		
	OnEvent += handleToEventHandler;
		
	/ ... /
	
	OnEvent -= handleToEventHandler;</pre>Does this sound right.  I have not tried it yet, since I was hoping there was a better way, and also I wanted to do some gripping about C#'s auto-magical delegate system for handling events.  Which have created problems, at least for me.  Mainly when you want to wrap another object, and provide pass through event handling, you can not.  Your wrapper class has to register for the events, and then provide its own delegates for handling it.  Also when you want to do something like subscribe and unsubscribe to an event it seams like subscribing is no big deal, but unsubscribing seams like it comes with a little extra (more like annoying) work.<br />
<br />
Just to say it, I think the Java event handling system was far better and more flexible.  There was nothing going on auto-magically under the covers.  You new there was a Collection holding all the classes who subscribed, and that they are required to have a method signature that you will call when it is thrown.  There were standardized add/remove methods that all you have to do is pass the object who subscribed which was 99% of the 'this' keyword.  You always hand a handle to the object you used to subscribe to it with.<br />
<br />
Well that’s it with my gripping about C# events.  If someone can confirm that above is the correct and only way to subscribe and unsubscribe to an event, or provide a alternative solution.<br />
<br />
:laugh: Thanks for putting up with me.  ;P<br />
