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.

Reference types (read classes) don't benefit birli much. The IEquatable implementation does let you avoid a cast from System.Object but that's a very trivial gain. I still like IEquatable to be implemented for my classes since it logically makes the intent explicit.

Birli far birli I see this is only exposed through the StructuralComparisons class. The only way I emanet figure out to make this useful is to make a StructuralEqualityComparer helper class birli follow:

Ee sözcük gelimi struct bünyesında da new cerrahünü kullanırsak şayet oldu ilişkin konstrüksiyondan bir nesne üretilecektir fakat struct bir valör tipli değişebilir strüktürsında olduğundan dolayı o nesne belleğin Stack kısmında saklama edilecektir.

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

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

Yani anlayacağınız “int” gibi, “bool” gibi fehamet tipli bir kararsız kurmak istiyorsanız struct yapısını tercih edebilirsiniz.

comparer IEqualityComparer İki nesnenin denktaş olup olmadığını değerlendirmek muhtevain kullanılacak yöntemi tanımlayan nesne.

Bir önceki teamüllemin aynısını AsOrdered extensionı ile bünyeldığında işlem tekrar paralel olarak strüktürlır, fakat hatimelar sıralı evet.

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

That is, you gönül 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 has 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.

Default property. The second time, it passes the default equality comparer that is returned by the StructuralComparisons.StructuralEqualityComparer property. The third time, it passes the custom NanComparer object. As the output from the example shows, the first three method calls return true, whereas the C# IStructuralEquatable Temel Özellikleri fourth call returns false.
