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.

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and not just compare references or individual values.
I'm amazed that the most important reason is not mentioned here. IEquatable was introduced mainly for structs for two reasons:
comparer IEqualityComparer An object that determines whether the current instance and other are equal.

Reading through the excellent blog post by Sergey on struct equality performance he mentions that the default implementations are pretty slow and using boxing for each member. Additionally, he mentions that a memory comparison may not give you the correct results in this super simple example:
Task oluşturmanın kârlemci üzerinde maliyeti vardır ve çok kısa devam eden medarımaişetlemler bağırsakin bir task oluşturmak genelde henüz yavaş çhileışan uygulamalara münasebet olabilir.
Fakat, fruits1 ve fruits3 dizileri aynı elemanlara farklı sıralarda malik olduğundan, CompareTo metodu farklı bir değer döndürür ve bu dizilerin strüktürel olarak müsavi olmadığını belirtir.
IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.

3 feature called Tuple Equality! That is right, you kişi create a ValueTuple and simply compare them birli they are super optimized, don't create any objects, and reduce this to a single line of code!
