Why do we have IStructuralComparable and IStructuralEquatable when there already exist the IComparable and IEquatable interfaces? The answer I would offer is that, in general, it's desirable to differentiate between reference comparisons and structural comparisons.

If you want to implement IEquatable in a class hierarchy you gönül use the following pattern. It prevents derived (including sibling) classes from being equal.

Let us not forget about additional operators and not just relying on Equals. We güç implement the == and != operators easily:

Your concern is that Object.GetHashCode() does derece provide values that are stable and the concern is very valid birli sevimli be seen in the first box headed by Caution in the documentation:

After some more testing I found that any two arrays with the same first element have the same hash. I still think this is strange behavior.

Ancak, articles1 ve articles3 dizileri aynı makale kellelıklarına farklı sıralarda sahip başüstüneğundan, CompareTo metodu farklı bir paha döndürür ve bu dizilerin konstrüktif olarak eşit olmadığını belirtir.

(doesn't violate documentation), but it is clearly hamiş bey good as it would be if 0 were replaced with i. Also there's no reason to loop if the code were just going to use a single value from the array.

When working with collections or structures where the order of elements matters, and you want C# IStructuralEquatable Kullanımı to compare their structures, IStructuralEquatable sevimli be useful.

Defines methods to support the comparison of objects for structural equality. Structural equality means that two objects are equal because they have equal values.

The IStructuralEquatable interface supports only custom comparisons for structural equality. The IStructuralComparable interface supports custom structural comparisons for sorting and ordering.
