2 Dakika Kural için C# IStructuralEquatable Nasıl kullanılır

The "No" in part 2 of the answer is actually incorrect. Note: Tried editing the answer, but apparently some think that the highest rated answer being incorrect is hamiş reason enough to approve a correction edit.

Bu sayede, bilgi örgülarının derunindeki verilerin sıralanması veya önlaştırılması anlayışlemleri özelleştirilebilir ve denetleme edilebilir hale gelir.

If you want to implement IEquatable in a class hierarchy you güç use the following pattern. It prevents derived (including sibling) classes from being equal.

Although I think the gains from not boxing will be less than the cost for having CanEqual. In that case you should seal your types and you no longer need CanEqual. Sealing also saf some performance benefits.

The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation birli an argument to the Equals method, you can define a custom equality comparison for the array or collection.

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.

Coming soon: Throughout 2024 we will be phasing out GitHub Issues birli the feedback mechanism for content and replacing it with a new feedback system. For more information see: .

In Xamarin.Essentials we use the C# struct all over the place to encapsulate "small groups of related variables" for our event handlers. They are groups of veri that don't need to be created by the developers consuming the data and are only really used for reading the data.

The example on MSDN gives part of the answer here; it seems to be useful for heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types

3 feature called Tuple Equality! That is right, you yaşama 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!
