The mere fact that it's an interface separates the implementation of the interface from its definition, and allows you to substitute different implementers.
Properties StructuralComparer Gets a predefined object that performs a structural comparison of two objects.
The IEqualityComparer from input parameter is used, in here you input StructruralEqualityComparer but int does derece implement IStructruralEquatable, so it uses default comparer for int which is value equality.
However, you do not call the CompareTo method directly in most cases. Instead, the CompareTo method is called by sorting methods such as Sort(Array, IComparer). In this case, you define your IComparer implementation and pass it birli an argument to a sorting method or collection object's class constructor. The CompareTo method with your custom comparer is then called automatically whenever the collection is sorted.
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 derece mutually exclusive.
Fevkdaki kodda, dizi1 ve dizi2 isminde iki saf oluşturulmuşdolaşma. Her dü dizinin de elemanları nüshadır. Şimdi, bu dizileri StructuralComparer kullanarak içinlaştıracağız:
Yapısal katlaştırma, C# StructuralComparisons Kullanımı elemanların sırası ve kıymeti üzerinden gerçekleştirilir ve muta gestaltlarının bağırsakeriklerinin aynı olup olmadığını sınırlamak sinein kullanılır.
CompareTo(Object, IComparer), its Compare method is called for each member of an array or for each component of a tuple. This implementation of the Compare method behaves bey follows C# StructuralComparisons Temel Özellikleri when it compares each item of a collection object with the corresponding item of another collection object:
Coming soon: Throughout 2024 we will be phasing out GitHub Issues bey the feedback mechanism for content and replacing it with a new feedback system. For more information see: .
And as a result, default equality checks need two of the compared items to be the same type but StructuralEqualityComparer doesn't require them to be same type. Kakım the name suggests it is supposed C# StructuralComparisons Nedir to compare contents.
You don't implement explicitly an equality operator, so == is derece defined particularly for the type.
It considers two items that are null to be equal, and considers a null item to be less than an item that is derece null.
