When overriding a class such as:

       public override void OnCreate()

Open in new window

Is it best to call the base method BEFORE or AFTER your code? And reasons why please.

Thanks :)

Depends on what you do.  Sometimes before, sometimes after, sometimes makes no difference.

Well typically the base implementation is what actually raises the event. The decision you have to make is whether not you want the client to see the event before your code runs or after your code runs, or to never see it all. ( more or less what Andy said. )

Example :

For Constructor you mostly set it first : you are then sure that it's constructed
For destruction set is as last : you want it to be destructed after you've destructed all the addon's

For the other methods, it's all about what the others said, just trying to clear it out a little more with the 2 examples

I guess I'll have to try it out and see what works best. I'm developing for Android, so I'm in the dark mostly :) Thanks for the help

Not to discredit my fellow experts, but you might try posting your question in the Android TA. (Myself, I have only dabbled in Android development.)
