It's normally expected that if you implement IEquatable.Equals you will also override Object.Equals to be consistent. In this case how would you support both reference and structural equality?
In this case you don't want to change your class implementation so you don't wantoverride the Equals method. this will define a general way to compare objects in your application.

As an example, it might make sense for two different instances of an Employee class to be considered equal if they both represent the same entity in your system.
The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.
The IEquatable implementation will require one less cast for these classes and bey a result will be slightly faster than the standard object.Equals method that would be used otherwise. Birli an example see the different implementation of the two methods:
Yani anlayacağınız “int” kabilinden, “bool” gibi haysiyet tipli bir mütehavvil peyda etmek istiyorsanız struct yapkaloriı yeğleme edebilirsiniz.
The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .

He, makalede eksiklikler olur. Bunu tenkit olarak onaylama ediyorum. Işlevsel programlamada struct kullanılmasının nedenini bile bilmiyor, performans ve diğer mevzular üzerine da rastgele bir düşünüm barındırmıyorum. Siz biliyorsanız lütfen aydınlatır mkaloriız?
The IStructuralEquatable interface supports only custom comparisons for structural equality. The IStructuralComparable interface supports custom structural comparisons for sorting and ordering.
