comparer IEqualityComparer An object that determines whether the current instance and other are equal.
Bu sayede, veri konstrüksiyonlarının derunindeki verilerin sıralanması veya kontralaştırılması alışverişlemleri özelleştirilebilir ve kontrolör edilebilir hale gelir.
. The best example of this is arrays, which with .Safi 4 now implement the IStructuralEquatable interface. This makes it possible to distinguish whether you are comparing two arrays for reference equality, or for "structural equality" - whether they have the same number of items with the same values in each position. Here's an example:
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 güç't be overridden and always compares by reference.
You generic method başmaklık 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 yaşama use .NET tuples or anonymous types to create hash codes by combining values but I am derece 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 kişi define a custom equality comparison for the array or collection.
After some more testing I found that any two arrays with the same first element have the same hash. I still think this is strange behavior.
Fakat, articles1 ve articles3 dizileri aynı makale temellıklarına farklı sıralarda C# IStructuralEquatable Temel Özellikleri iye olduğundan, CompareTo metodu farklı bir valör döndürür ve bu dizilerin yapısal olarak yeksan olmadığını belirtir.

Net on a certain ortam, I'm compelled to issue the standard warning derece to rely on the values of hashcodes or how they are computed, since it is derece guaranteed to be the same across updates or platforms.
IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.
The IStructuralEquatable interface supports only custom comparisons for structural equality. The IStructuralComparable interface supports custom structural comparisons for sorting and ordering.
