Re: [Mono-dev] FW: [Bug 349875] DictionaryTKey, TValue stores values out of order.
I recall reading somewhere that when possible, mono will try to mimic the behavior of .Net, to make it easier for people to migrate from the later to the former. I can't find that reference now, so maybe it's all in my head. :) -Original Message- From: Juraj Skripsky [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 19, 2007 2:17 PM To: Josh Mouch Cc: mono-devel-list@lists.ximian.com Subject: Re: FW: [Bug 349875] DictionaryTKey, TValue stores values out of order.

Re: [Mono-dev] FW: [Bug 349875] DictionaryTKey, TValue stores values out of order.
Hi, We do try to mimic MS behaviour but this case is hard to solve, as what seems to be the MS behaviour is probably just an accident due to their implementation of GetHashCode.

Re: [Mono-dev] FW: [Bug 349875] DictionaryTKey, TValue stores values out of order.
You're right, it's just the definition of (specified) behavior that we don't agree on. MS left out any ordering guarantees for Dictionary'2 on purpose. Specifying an order would have opened a very nasty can of worms. What would be the expected order after adding the keys 1, 2, 3, then removing 2 and then adding 4? 1-3-4 or 1-4-3? Thanks anyway for filling the bug report! Even if it wasn't really a bug, it's good to have as many people as possible testing and questioning the correctness of Mono. - Juraj On Wed, 2007-12-19 at 14:40 -0500, Josh Mouch wrote: I recall reading somewhere that when possible, mono will try to mimic the behavior of .Net, to make it easier for people to migrate from the later to the former.

Re: [Mono-dev] FW: [Bug 349875] DictionaryTKey, TValue stores values out of order.
Shouldn't the stack order always be first in first out? So with your example 1-2-3, remove 2, add 4, you would end up with 1-3-4. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Juraj Skripsky Sent: Wednesday, December 19, 2007 1:54 PM To: Josh Mouch Cc: mono-devel-list@lists.ximian.com Subject: Re: [Mono-dev] FW: [Bug 349875] DictionaryTKey,TValue stores values out of order.
