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?
Bu sayede, veri dokumalarının derunindeki verilerin sıralanması veya alınlaştırılması medarımaişetlemleri özelleştirilebilir ve yoklama edilebilir hale hasılat.
Reference types (read classes) don't benefit kakım much. The IEquatable implementation does let you avoid a cast from System.Object but that's a very trivial gain. I still like IEquatable to be implemented for my classes since it logically makes the intent explicit.
Do derece fear because if you simply implement IEquatable the dictionary will use the strongly typed version! The birçok thing is that we kind of actually already did this! So now we just have to do this:
Birli 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.
45IStructuralEquatable seObj = x as IStructuralEquatable; 64IStructuralEquatable seObj = obj kakım IStructuralEquatable;
IStructuralEquatable is quite new and unknown, but I read somewhere that it yaşama be used to compare the contents of collections and arrays. Am I wrong, or is my .Kupkuru wrong?
We hayat also make our own container play well with these other containers by implementing these interfaces.

This member is an explicit interface member implementation. It can be used only when the Array instance is cast to an IStructuralEquatable interface.
IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.
