C# why shall I use “new” keyword when subscribing for an event?

Question

What is the difference between following 2 ways of subscribing for an event?

receiver.ConfigChanged += Config_ConfigChanged;

receiver.ConfigChanged += new E         


        

Answer 1

Ok so

receiver.ConfigChanged -= Config_ConfigChanged;

will clear out all event handlers that refer to that method.

var eventHandler = new EventHandler(Config_ConfigChanged); 

receiver.ConfigChanged += eventHandler;
receiver.ConfigChanged += new EventHandler(Config_ConfigChanged); 

receiver -= eventHandler;

will only clear out the one eventHandler.

You use the verbose way if you don't care about tracking the handler.
