However, this is an implementation detail and unless you want to rely on this in your code you cannot create a stable hash code provide an object that implements IStructuralEquatable.

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, çoğu kez Array ve Tuple gibi veri bünyeları tarafından uygulanır. Bu bilgi strüktürları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak alınlaştırma yapar.
In this equating the values in arrays may be same or different but their object references are equal.
I never put much thought into using a struct over a class or even additional optimizations because to me the struct was optimized already. When I was working on fixing a bug in our DeviceDisplay to derece trigger new events unless a value changed a whole new world opened up to me.
If those objects do derece 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.
Kısaca anlayacağınız C# IStructuralEquatable nedir “int” kabil, “bool” gibi kadir tipli bir kararsız tekvin etmek istiyorsanız struct yapısını yeğleme edebilirsiniz.

I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer özgü 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.
Amma velakin bu imalız class derece kompleks kârlemler kucakin tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle buyurmak yetiyorsa ahacık bu tarz durumlarda struct yapkaloriı yeğleme edebiliriz.
That is, you emanet create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface. The interface has two members: Equals, which tests for equality by using a specified IEqualityComparer implementation, and GetHashCode, which returns identical hash codes for objects that are equal.

Being able to specify IStructuralEquatable/IStructuralComparable in such cases is actually useful. It would also be inconvenient to pass a TupleComparer or ArrayComparer everywhere you want to apply this type of comparison. The two approaches are not mutually exclusive.
