Why do we have IStructuralComparable and IStructuralEquatable when there already exist the IComparable and IEquatable interfaces? The answer I would offer is that, in general, it's desirable to differentiate between reference comparisons and structural comparisons.
Bu sayede, muta strüktürlarının sineindeki verilerin sıralanması yahut karşılaştırılması emeklemleri özelleştirilebilir ve yoklama edilebilir hale hasılat.
Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:
IStructuralComparable arayüzü, çoğu kez Array ve Tuple kabilinden data mimariları tarafından uygulanır. Bu muta mimariları, elemanlarının sıralamasını ve yapısını dikkate alarak huzurlaştırma yapar.
Bildiğiniz gibi new cerrahü classlarda kullanıldığı bugün alakadar classtan bir nesne talep edilmekte ve üretilen nesne belleğin Heap kısmında korunum edilmektedir.
Your concern is that Object.GetHashCode() does not provide values that are stable and the concern is very valid kakım gönül be seen in the first box headed by Caution in the documentation:
If those objects do hamiş contain equality/hashcode methods that satisfy that contract, you will have to wrap them and provide correct implementations for those methods yourself in the wrapper.
I've noticed these two interfaces, and several associated classes, have been added in .NET 4. They seem a bit superfluous to me; I've read several blogs about them, but I still kişi't figure out what mesele they solve that was tricky before .Safi 4.
The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .
In addition to this awesome blog Frank and I also dicussed all of this awesome in detail on Merge Conflict on episode 111:
This member is an explicit interface member implementation. It kişi be used only when the Array instance is cast to an IStructuralEquatable interface.
Do hamiş send hash codes across application domains or processes. In some cases, hash codes may be computed on a per-process or per-application domain basis.
Are the bonuses for infernal war machine weapon stations static, or are they affected by their user?
