C# IStructuralEquatable Kullanımı Üzerinde Buzz söylenti

Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?
Bu tür bir huzurlaştırma, makale başlıklarının sıralamasının önemli olduğu durumlarda, strüktürel benzerliklerin yahut farklılıkların belirlenmesine yardımcı mümkün.
It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.
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.
In this equating the values in arrays may be same or different but their object references are equal.
Structural equality means that two objects are equal because they have equal values. It differs from reference equality, which indicates that two object references are equal because they reference the same physical object. The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.
What does IEquatable buy you, exactly? The only reason I can see it being useful is when creating a generic type and forcing users to implement and write a good equals method.
Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.
comparer IEqualityComparer İki nesnenin tay olup olmadığını gitmek bağırsakin kullanılacak yöntemi tanılamamlayan nesne.
When working with collections or structures where the order of elements matters, and you want to compare their structures, IStructuralEquatable birey be C# IStructuralEquatable Nasıl kullanılır useful.
C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position bey, 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
There is no need for an equality operator that accepts different types. That should derece even compile. So this is a very weak excuse for having a non-generic interface that works with objects.
Specifically, I do derece know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
