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

In this case you don't want to change your class implementation so you don't wantoverride the Equals method. this will define a general way to compare objects in your application.

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

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 gönül't be overridden and always compares by reference.

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

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

IStructuralEquatable is quite new and unknown, but I read somewhere that it can be used to compare the contents of collections and arrays. Am I wrong, or is my .Kemiksiz wrong?

I've noticed these two interfaces, and several associated classes, have been added in .NET 4. They seem a bit superfluous to me; I've read several blogs about them, but I still dirilik't figure out what problem they solve that was tricky before .Safi 4.

Başka bir ifadeyle, kendi yapısal denklik tanımınızı oluşturabilir ve bu tanılamamın arabirimi akseptans IStructuralEquatable eden bir koleksiyon türüyle kullanılacağını belirtebilirsiniz. Arabirimin iki üyesi vardır: Equals, belirtilen IEqualityComparer bir uygulamayı kullanarak eşitliği test eder ve GetHashCodeeşit olan nesneler dâhilin aynı katışık kodları döndürür.

In all my years of development and blogging I never thought I would be writing about how amazing a C# struct is, how awesome IEquatable is, and how C# 7 features make implementing all of it mind blowing.

This member is an explicit interface member implementation. It sevimli be used only when the Array instance is cast to an IStructuralEquatable interface.

That is, you can create your own definition of structural C# IStructuralEquatable Nasıl kullanılır 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 derece conflict with the documentation and there is no bug in the implementation.
