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.
Bu sayede, done yapılarının bağırsakindeki verilerin sıralanması yahut muhaliflaştırılması meselelemleri özelleştirilebilir ve denetçi edilebilir hale gelir.
It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

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.
1 My understanding is that it's used for collection like types, and encapsulates the structural part of the comparison, but leaved the comparison of the elements to a comparer passed in by the user. But I'm derece really sure if I really got it.
This is very disappointing behaviour from Microsoft; I'm now wondering if I should review the list of cases I've filed and see if other ones I've submitted have been removed...
The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .
If you read this entire post and are thinking wow that is a lot of code and steps to remember then do hamiş fear because Dustin told me and showed me that Visual Studio will generate all of this for you!!!!! Check this out:
This member is an explicit interface member implementation. It birey be used only when the Array instance is cast to an IStructuralEquatable interface.
