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

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

Yazgımızın fevkdaki satırlarında da bahsettiğimiz kabil struct C#’ta value type yaratabileceğimiz bünyedır.

You generic method has a type parameter T but the type is not part of the signature of the function so how is T supposed to be used in the function? Anyway, you dirilik use .NET tuples or anonymous types to create hash codes by combining values but I am hamiş sure this answers your question.

The IEquatable implementation will require one less cast for these classes and as a result will be slightly faster than the standard object.Equals method that would be used otherwise. Bey an example see the different implementation of the two methods:

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

Reading through the excellent blog post by Sergey on struct equality performance he mentions that the default implementations are C# IStructuralEquatable nerelerde kullanılıyor pretty slow and using boxing for each member. Additionally, he mentions that a memory comparison may hamiş give you the correct results in this super simple example:

If you read this entire post and are thinking wow that is a lot of code and steps to remember then do derece fear because Dustin told me and showed me that Visual Studio will generate all of this for you!!!!! Check this out:

Amma velakin bu özümlemeız class denli kompleks alışverişlemler ciğerin tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle kılmak yetiyorsa aha bu şekil durumlarda struct yapısını yeğleme edebiliriz.

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 .Kemiksiz 4.0 int, string will internally implement IEquatable for custom types we have to externally implement the IEquatable.

3 feature called Tuple Equality! That is right, you gönül create a ValueTuple and simply compare them kakım they are super optimized, don't create any objects, and reduce this to a single line of code!
