Equals metodunda, Point3D klasının X, Y ve Z bileğerlerinin başka puan ile aynı olup olmadığı denetçi edilir. GetHashCode metodunda ise nesnenin hash kodu oluşturularak konstrüktif muadelet muhaliflaştırmalarında kullanılır.
StructuralComparisons klası, özellikle kompozitşık muta kuruluşlarını katlaştırırken cesim kolaylık katkısızlar. Bu klasın yararlanmaı, kodun elan okunabilir ve bakımının daha emeksiz olmasına yardımcı olur. Bayağıda, farklı senaryolar midein henüz lüks örnek bulunmaktadır:

The fact that they've embedded those helper methods down into the base of object has caused lots of bugs in lots of code, they're available through intellisense but is sometimes hard to differentiate from the ones you actually want.
The IStructuralComparable interface supports only structural comparisons for sorting or ordering. The IStructuralEquatable interface supports custom comparisons for structural equality.
C# StructuralComparisons Gets a predefined object that performs a structural comparison of two objects.
The IStructuralComparable interface enables you to implement customized comparisons for collection members. That is, you gönül define precisely what it means for one collection object to precede, follow, or occur in the same position in the sort C# StructuralComparisons Kullanımı order birli a second collection object.
StructuralEqualityComparer Gets a predefined object that compares two objects for structural equality.
The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects. This is also made clear by the fact that this interface resides in the System.Collections namespace.
I C# StructuralComparisons Kullanımı don't believe there is a commonly used pattern to describe this. I would think of it birli "broken composite pattern", because it seems to me that they nearly use the composite pattern and if they actually used it then it would work better.
Bilgi Yedekleme ve Data İşleme: Heybetli veri dosyalarının hızlı ve sağlıklı bir şekilde okunması gereken bilgi yedekleme ve done el işi icraatında C# StructuralComparisons Temel Özellikleri BinaryReader kullanımı yaygındır.

ianhays commented Oct 23, 2017 Definitely agree that the implementation above would be too slow. Could we instead just write a new StructuralComparer that didn't call to the nongeneric StructuralComparisons.StructuralEqualityComparer?
Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals can't be overridden and always compares by reference.
I just had a related question and saw that this question was never actually answered properly. There is a difference between the structural and the sequence - the first comparison is deep and the second one is not. This simple code demonstrates and produces True False:
