It's normally expected that if you implement IEquatable.Equals you will also override Object.Equals to be consistent. In this case how would you support both reference and structural equality?
Bu tür bir karşılaştırma, makale esaslıklarının sıralamasının önemli olduğu durumlarda, strüktürel benzerliklerin veya değişiklıkların belirlenmesine yardımcı kabil.
Will feeblemind affect the original creature's body when it was cast on it while it was polymorphed and reverted to its original form afterwards?
IStructuralComparable arayüzü, alelumum Array ve Tuple üzere veri mimariları tarafından uygulanır. Bu veri kuruluşları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak hakkındalaştırma yapar.
In this equating the values in arrays may be same or different but their object references are equal.
45IStructuralEquatable seObj = x bey IStructuralEquatable; 64IStructuralEquatable seObj = obj as IStructuralEquatable;
So, I am apparently wrong as unequal objects may have equal hash codes. But isn't GetHashCode returning a somewhat randomly distributed seki of values a requirement?
I've noticed these two interfaces, and several associated classes, have been added in .Kemiksiz 4. They seem a bit superfluous to me; I've read several blogs about them, but I still emanet't figure out what problem they solve that was tricky before .Kemiksiz 4.
The first issue we see here is that this struct is mutable in that you can actually change the veri later on via the set properties. There was no real reason that we introduced this except that we were used to it.

This member is an explicit interface member implementation. It gönül be used only when the Array instance is cast to an IStructuralEquatable interface.
Now that our struct is immutable the actual issue comes up when you need to compare these values. When I started to write the code to fix the bug I just decided that "hey I have the old values, I hayat just compare each of them":

The Equals method supports custom structural comparison of array and tuple objects. This method in turn calls the comparer object's IEqualityComparer.Equals method to compare individual array elements or tuple components, starting with the first element or C# IStructuralEquatable nedir component.
