I'm trying to find the absolute most lightweight, efficient array type that supports: 1. Strongly-typed entries (e.g. not all items of type "Object") 2. Ability to Add() and Remove() I see that the C# built-in array type doesn't support resizing. The framework ArrayList supports resizing but doesn't seem to allow a fixed entry type. How do I do this?

If that's too long to wait, I believe there are various "properly strongly typed" collection class generators available on the net, that will give an ArrayList-like interface with a strongly typed backing array. (That gets round the boxing problem for value types.) -- Jon Skeet - <Click here to reveal e-mail address> http://www.pobox.com/~skeet If replying to the group, please do not mail me too Reply to this message...        Alex Maghen (VIP) Wow... really? I mean... wow. Doesn't that seem like a somewhat... starnge thing not to have as integral to... y'know what? Far be it from me to criticize. Not like I wrote .NET or anything. Okay, thanks.

The type safety issue is definitely something I'll be pleased not to have to worry about, but I can't think of a single time where it's been an actual problem for me. -- Jon Skeet - <Click here to reveal e-mail address> http://www.pobox.com/~skeet If replying to the group, please do not mail me too Reply to this message...        Jakob Christensen I have used Chris Sells collection generator on several occasions (couldn't wait for Whidbey). His collections use strongly typed backing arrays (as John Skeet mentions) except for the strongly typed hashtables. http://www.sellsbrothers.com/tools/#collectionGen Regards, Jakob.
