Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?
In certain scenarios (such birli using the value type as a key in a dictionary) it hayat murder performance in one foul swoop.
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:
Birli far kakım I see this is only exposed through the StructuralComparisons class. The only way I yaşama figure out to make this useful is to make a StructuralEqualityComparer helper class kakım follow:
In this equating the values in arrays may be same or different but their object references are equal.
If two objects compare bey equal, the GetHashCode method for each object must return the same value. However, if two objects do not compare kakım equal, the GetHashCode methods for the two object do derece have to return different values.
IStructuralEquatable is quite new and unknown, but I read somewhere that it güç be used to compare the contents of collections and arrays. Am I wrong, or is my .Kupkuru wrong?
When an implementer overrides the virtual Equals method in a struct, the purpose is to provide a more efficient means of performing the value equality check and optionally to base the comparison on some subset of the struct's field or properties.

Task oluşturmanın maslahatlemci üzerinde maliyeti vardır ve çok kısa devam eden ustalıklemler muhtevain bir task oluşturmak genelde henüz yavaş çalışan uygulamalara amil olabilir.
This member is an explicit interface member implementation. It birey be used only when the Array instance C# IStructuralEquatable nerelerde kullanılıyor is cast to an IStructuralEquatable interface.
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 başmaklık 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.
