If equality is hamiş needed for the derived class you can skip IEquatable but you need to override the CanEqual to prevent it being equal with base classes (unless of course they should be considered equal).
1 How do such comparators relate to things like Dictionary and other collections? I know that Dictionary seems to handle structures sensibly albeit slowly in .
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, ekseriya Array ve Tuple gibi bilgi mimariları tarafından uygulanır. Bu bilgi bünyeları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak alınlaştırma yapar.
In this equating the values in arrays may be same or different but their object references are equal.
The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.
Aynı hizmetlemi her bir iterasyon için bir task oluşturup yapabiliyorken niçin Muvazi bir döngü oluşturmalıyız?
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

Bu örnekte, articles1 ve articles2 dizileri aynı C# IStructuralEquatable Temel Özellikleri makale çıbanlıklarına aynı tam iye olduğundan, CompareTo metodu 0 döndürerek bu dizilerin konstrüktif olarak denktaş bulunduğunu belirtir.
C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position kakım, or follows another object in the sort order.
The example on MSDN gives part of the answer here; it seems to be useful for heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types
