Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?
Bu sayede, muta konstrüksiyonlarının bâtınindeki verilerin sıralanması veya mukabillaştırılması konulemleri özelleştirilebilir ve muayene edilebilir hale hasılat.
The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.
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 fourth call returns false.
Let us hamiş forget about additional operators and derece just relying on Equals. We dirilik implement the == and != operators easily:
comparer IEqualityComparer An object that determines whether the current instance and other are equal.
What does IEquatable buy you, exactly? The only reason I dirilik see it being useful is when creating a generic type and forcing users to implement and write a good equals method.

Farklı bir ifadeyle, kendi strüktürel eşitlik tanımınızı oluşturabilir ve bu teşhismın arabirimi onaylama IStructuralEquatable fail bir koleksiyon türüyle kullanılacağını belirtebilirsiniz. Arabirimin C# IStructuralEquatable Temel Özellikleri dü üyesi vardır: Equals, belirtilen IEqualityComparer bir uygulamayı kullanarak eşitliği test değer ve GetHashCodeeşit olan nesneler bâtınin aynı katışık kodları döndürür.
In addition to this awesome blog Frank and I also dicussed all of this awesome in detail on Merge Conflict on episode 111:
C# IStructuralEquatable Defines methods to support the comparison of objects for structural equality.
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 .Safi 4.0 int, string will internally implement IEquatable for custom types we have to externally implement the IEquatable.
