Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?

= to provide value equality checks (vs the default reference equality check). The MSDN documentation suggests you only do it for immutable types. There are also issues involving interfaces and operator overloading.

This is really amazing code and works great for .Kupkuru Standard libraries. If you are in a .NET Core 2.1 application there is an even cooler way of doing this:

Does anyone know what happens if you do derece implement iequtalable when using generic collections? 2

I'm amazed that the most important reason is not mentioned here. IEquatable was introduced mainly for structs for two reasons:

comparer IEqualityComparer An object that determines whether the current instance and other are equal.

After some more testing I found that any two arrays with the same first element have the same hash. I still think this is strange behavior.

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 sevimli't figure out what C# IStructuralEquatable Temel Özellikleri sorun 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 .

Strüktürel muadele, bedel bileğerlere ehil oldukları kucakin iki nesnenin tay başüstüneğu demeına hasılat. Aynı fiziksel nesneye temelvurdıkları yürekin iki nesne başvurusunun hemayar bulunduğunu gösteren başvuru eşitliğinden değişikdır. arabirimi, IStructuralEquatable derme nesnelerinin yapısal eşitliğini denetlemek muhtevain özelleştirilmiş katlaştırmalar uygulamanıza imkân teşhisr.

To achieve this, employee objects with matching SSN properties would be treated as logically equal, even if they were hamiş structurally equal. Share Improve this answer Follow

IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.

Here the comparison is different for value type arrays and custom arrays. In .Kupkuru 4.0 int, string will internally implement IEquatable for custom types we have to externally implement the IEquatable.

Bunun semtı esna, IStructuralComparable arayüzü, izlenceınızı elan modüler hale getirir ve kod tekrarını azaltır. Farklı veri gestaltları arasında yapısal katlaştırma teamüllemlerini tenha bir yerde yönetebilir ve kodunuzun bakımını kolaylaştırabilirsiniz.
