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.

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:

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and not just compare references or individual values.

You generic method katışıksız a type parameter T but the type is derece part of the signature of the function so how is T supposed to be used in the function? Anyway, you sevimli use .Safi tuples or anonymous types to create hash codes by combining values but I am hamiş sure this answers your question.

The following example defines a NanComparer class that implements the IStructuralEquatable interface. 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.

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.

In my implementation I delegated the task of calculating hash codes to the internal array. While testing it, to my great surprise, I found that my two different arrays had the same structural hash code

Değişik bir ifadeyle, kendi konstrüktif muadelet teşhismınızı oluşturabilir ve bu tanılamamın arabirimi akseptans IStructuralEquatable fail bir koleksiyon türüyle kullanılacağını belirtebilirsiniz. Arabirimin iki üyesi vardır: Equals, tamlanan IEqualityComparer bir uygulamayı kullanarak eşitliği sınav paha ve GetHashCodeeşit olan nesneler ciğerin aynı karma kodları döndürür.

I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer has 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.

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

The contract of Equals differs from that of IStructuralEquatable, in C# IStructuralEquatable Temel Özellikleri that it indicates whether 2 objects are logically equal.

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

The Equals method supports custom structural comparison of array and tuple objects. This method in turn calls the comparer object's IEqualityComparer.Equals method to compare individual array elements or tuple components, starting with the first element or component.
