Eventhandlers, C#, VS2005

help, help, help.

The microsoft documentation is getting me in a tizzy.

What is the difference between the following:

timer1.Tick += new System.EventHandler(timer1_Tick);

&

timer1.Tick += this.timer1_Tick;

They both compile and look like they work the same.

Sorry... The shorter:

timer1.Tick += this.timer1_Tick

Is the new method. It's really just shorter syntax for the "+= new"
version.

It's just a syntax shortcut, if you check the compiled code, it is
compiled into the same IL..

Hi Gina,

It's a preference thing. What ever you feel comfortable with using. The
compiler can infer what you're trying to do, rather than you explicitally
tell it what you want it to do... so if you feel comfortable reading your
code, and knowing what the compiler is going to do when it reaches that
line (i.e. knowing that it will infer the new System.EventHandler(...)
part), then stick to short-hand.

Google first, ask later.

thanks Tom and everyone for helping clarify this.

I come from the Delphi realm where the specifics are sometimes hidden
from you and you start taking them for granted.

Yes, I know. I didn't mean to imply otherwise.
