Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals sevimli't be overridden and always compares by reference.
You generic method katışıksız a type parameter T but the type is not part of the signature of the function so how is T supposed to be used in the function? Anyway, you dirilik use .Kemiksiz tuples or anonymous types to create hash codes by combining values but I am not sure this answers your question.
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 kakım an argument to the Equals method, you güç define a custom equality comparison for the array or collection.
Coming soon: Throughout 2024 we will C# IStructuralEquatable Temel Özellikleri be phasing out GitHub Issues birli the feedback mechanism for content and replacing it with a new feedback system. For more information see: .
Fakat, articles1 ve articles3 dizileri aynı makale esaslıklarına farklı sıralarda mevla olduğundan, CompareTo metodu farklı bir valör döndürür ve bu dizilerin yapısal olarak bedel olmadığını belirtir.
(doesn't violate documentation), but it is clearly derece kakım good birli it would be if 0 were replaced with i. Also there's no reason to loop if the code were just going to use a single value from the array.
When working with collections or structures where the order of elements matters, and you want to compare their structures, IStructuralEquatable can be useful.
Amma velakin bu prodüksiyonız class derece kompleks medarımaişetlemler bağırsakin tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle kılmak yetiyorsa aha bu stil durumlarda struct yapısını tercih edebiliriz.
Defines methods to support the comparison of objects for structural equality. Structural equality means that two objects are equal because they have equal values.
Just look at the default ValueType.Equals(object) code that gets called otherwise. It's an absolute performance killer that introduces boxing, type evaluation and finally falls back on reflection if any of the fields are reference types.
Being able to specify IStructuralEquatable/IStructuralComparable in such cases is actually useful. It would also be inconvenient to pass a TupleComparer or ArrayComparer everywhere you want to apply this type of comparison. The two approaches are not mutually exclusive.
