ASP.NET Web Controls , How to implement eventhandlers

1. How is "myButton.Click -= new EventHandler(myButton_Click)" implemented? - CSharp/C#

2. To New(EventHandler) or !To New(EventHandler)

I recently installed Resharper to give it a try, and it has made me
wonder about a few things.  The most curious of which concerns event
handlers.  Every single example I've ever seen, every line of real
code I've ever seen, and every demo I've ever seen follows the same
patters.

SomeEvent += new EventHandler(EventHandlerMethod);

...

private void EventHandlerMethod(object sender, EventArgs e)
{
    ...
}


Resharper has been suggesting that the 'new EventHandler()' is
unnecessary code.  When I tell it to do it's thing, it changes the
line of code to

SomeEvent += EventHandlerMethod;

I've since been using the latter form to keep Resharper happy, and
because it looks cleaner.

My questions are, is this acceptable?  Is this going to cause some
kind of problem or strangeness that I'm not aware of?  If there are no
problems with this form, why does Everyone use the new EventHandler
form?


Thanks,

John

3. "must implement" AND "cannot implement" - .Net Framework

5. Newbie Help Request :Class implements an interface that implements another interface - CSharp/C#

6. Interfaces, Implements and Implements...

Hello,



why is it necessary to implement every procedure of an interface by
assigning it manually with another "implements" to the corresponding
procedure of the class, which actually implements the interface. Isn't the
name of the procedure good enough for assigning it unambiguously? I mean,
it's enough with simply deriving one class from another one?



My first thought was, it has something to do with the case sensitivity,
which would be taken into account at least "behind" the Implements-keyword.
But that's not the case (literally ;-).



I've been doing C# until know, so I apologize in advance, if this is a
stupid question.




Thanks for giving it a thought

I took System.Threading.Timer! Works now.
