It's normally expected that if you implement IEquatable.Equals you will also override Object.Equals to be consistent. In this case how would you support both reference and structural equality?
Bu tür bir muhaliflaştırma, makale kellelıklarının sıralamasının önemli evetğu durumlarda, strüktürel benzerliklerin veya farklılıkların belirlenmesine yardımcı olur.
That is right! When we override Equals we must also override and implement GetHashCode. I am no HashCode expert, but in the same article from Sergey is a snippet of using a ValueTuple to simplify this entire call to 1 line of code just like our fancy ValueTuple Equality above.
IStructuralComparable arayüzü, genellikle Array ve Tuple kabil done binaları tarafından uygulanır. Bu done yapıları, elemanlarının sıralamasını ve yapısını dikkate alarak mukabillaştırma yapar.
In this equating the values in arrays may be same or different but their object references are equal.

Bu örnekte, articles1 ve articles2 dizileri aynı makale sarrafiyelıklarına aynı tam malik olduğundan, CompareTo metodu 0 döndürerek bu dizilerin yapısal olarak eşit bulunduğunu belirtir.
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.
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. Bey the output from the example shows, the first three method calls return true, whereas the fourth call returns false.
