Regions: Love or Hate

Now I hate them, each member of our team uses them differently.

I think that's the issue right there .. its not regions that's the problem .. its inconsistent use. You could say the same for any tool/practice. I use them to group things away that I don't need to see, like private members etc, and I use them consistently for this reason.

The only thing unpredictable about me is just how predictable I'm going to be.

I always say : when you use region, just create another class ! It's useful only for generated code (like proxy class for web services)

[BrianPayne]

I LOVE regions, but only on a structured, limited basis. They are helpful to organize the class, but can get unruly if overused. I stick to several standard regions and alphabetize my methods, properties, etc, so that everything is easy to find. - Catalyst

It seems to me that you really don't hate regions, you just hate how they've been misused.

I liked the idea but didn't use them very often because they didn't stand out when collapsed. After changing the “Collapsed Text” to orange in the options I use them a lot. Tools/Options/Environment/Fonts and Colors/Collapsed Text/Item foreground

I find them useful to separate true regions in the code, i.e., constructors, private properties, public properties, private methods and public methods. They are useful especially in code-behind pages with a lot of code that make for a lot of scrolling. When I collapse the code page to definitions, they are all you see between the class definition and Namespace declarations, making it easy to expand the region I'm looking for to view, edit or add to. Most of the comments I've seen here that oppose them seem to direct their hatred at how they are (mis)used, but don't really say why regions are in themselves bad. That's kind of like hating pencils because they can be used to write bad English. :)

idiots people who like stupid space-wasting, conceptually-disorganized styles like Allman. But I guess the use of inferior editors that are incapable of brace matching, as well as dysfunctional eyes that cannot scan up-/downward to matching indents, are all factors in why they would give up as real developers need to use such a style. That, or they just really, really, really love Microsoft. 1TBS or GTFO

This is what I call abuse/overuse. It makes my eyes roll back in my head when I see this crap, comments would've been more than sufficient.

I don't use them. I use Visual Studio's class explorer to navigate to the desired member, so don't need them. I don't mind if anybody else uses them though...

[John Boyett]

That makes a lot of sense. I might try using them that way.

If anything, that is an even more retarded differently-abled variant of Allman. You have my sympathies. Hopefully, you are functional enough to be allowed to live a [mostly] normal adult life.

That is a horrible misuse. Regions should never be used inside a code block, IMO.

[Kabwla Phone]

I think this is a good example of good usage. The advantage a region has over a comment is that a region can signal the end of your logical block. With a comment you would have to asume that the comment is valid until the next comment. And as you know, assumtion makes an ... out of u and me.

[Alan Burkhart]

I generally group code blocks in regions according to purpose. The file menu and edit menu each gets its own region, and printing, if the project does any printing. It helps me stay organized and makes various blocks of code easier to find.

That. Is. Insane.

Having spent the last 10-15 minutes learning more than I ever knew, cared to know, or ever dreamed there was to know, about the names (people waste their lives inventing names for this stuff???) and histories of these various indentation styles, I now feel my brain has been eternally and irrevocably damaged for the effort. Of all the 15 minute spans of my life that have gone to waste, I believe this one will be lamented the most. And, sorry, have to agree with the last poster about your choice of styles. :)

[Fabio Franco]

I find them useful to separate different regions inside a big class, like fields, properties, methods and constructors

Place the public stuff first. That is where the story of your class starts
