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.

g. MyType and Object) which will still use the identity comparison. I suspect it's not a great idea to do this unless it's going to be a very heavily used type in your code, where everyone will become very familiar with it and

In this equating the values in arrays may be same or different but their object references are equal.

I never put much thought into using a struct over a class or even additional optimizations because to me the struct was optimized already. When I was working on fixing a bug in our DeviceDisplay to derece trigger new events unless a value changed a whole new world opened up to me.

If those objects do not contain equality/hashcode methods that satisfy that contract, you will have to wrap them and provide correct implementations for those methods yourself in the wrapper.

Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.

The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .

In addition to this awesome blog Frank and I also dicussed all of this awesome in detail on Merge Conflict on episode 111:

Amma velakin bu konstrüksiyonız class kadar kompleks medarımaişetlemler midein tasarlanmış C# IStructuralEquatable nerelerde kullanılıyor bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle buyurmak yetiyorsa ahacık bu üslup durumlarda struct yapısını yeğleme edebiliriz.

He, makalede nekais kabil. Bunu tenkit olarak ikrar ediyorum. Fonksiyonel programlamada struct kullanılmasının nedenini de bilmiyor, başarım ve özge konular karşı da herhangi bir fikir barındırmıversiyon. Siz biliyorsanız lütfen aydınlatır mısınız?

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.
