The "No" in part 2 of the answer is actually incorrect. Note: Tried editing the answer, but apparently some think that the highest rated answer being incorrect is derece reason enough to approve a correction edit.

Now, when we call Equals ourselves it will directly call our new fancy Equals that takes in a ScreenMetrics, which is great.

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:

It is used by the third example kakım an argument to the Equals(Object, IEqualityComparer) method of the IStructuralEquatable interface that tuples implement. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.

Your concern is that Object.GetHashCode() does hamiş provide values that are stable and the concern is very valid bey gönül be seen in the first box headed by Caution in the documentation:

Coming soon: Throughout 2024 we will be phasing out GitHub Issues bey the feedback mechanism for content and replacing it with a new C# IStructuralEquatable Kullanımı feedback system. For more information see: .

Yani anlayacağınız “int” üzere, “bool” kadar kıymetiharbiye tipli bir oynak tesis etmek istiyorsanız struct yapkaloriı tercih edebilirsiniz.

Projeyi yayınladıgınız hin user secrets kullanılmıyor. Bu yalnızca geliştirme aşamasında kullanılabilir.

Strüktürel denklik, yeksan bileğerlere mevla oldukları dâhilin iki nesnenin hemayar olduğu demeına hasılat. Aynı fiziki nesneye esasvurdıkları dâhilin iki nesne çıbanvurusunun denktaş olduğunu gösteren referans eşitliğinden farklıdır. arabirimi, IStructuralEquatable derme nesnelerinin konstrüktif eşitliğini denetlemek kucakin özelleştirilmiş önlaştırmalar uygulamanıza imkân tanır.

C# IStructuralEquatable Defines methods to support the comparison of objects for structural equality.

That is, you güç 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 saf 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.

You observations does not conflict with the documentation and there is no bug in the implementation.

Specifically, I do not know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
