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, done dokumalarının bâtınindeki verilerin sıralanması yahut alınlaştırılması teamüllemleri özelleştirilebilir ve denetçi edilebilir hale hasılat.
. The best example of this is arrays, which with .Kemiksiz 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:
Bey far as I see this is only exposed through the StructuralComparisons class. The only way I güç figure out to make this useful is to make a StructuralEqualityComparer helper class as follow:
It is used by the third example as an argument to the Equals(Object, IEqualityComparer) method of the IStructuralEquatable interface that tuples implement. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.
The following example defines a NanComparer class that implements the IStructuralEquatable interface. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.
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 hamiş really sure if I really C# IStructuralEquatable nedir 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: .
comparer IEqualityComparer İki nesnenin yeksan olup olmadığını değerlendirmek kucakin kullanılacak yöntemi tanımlayan nesne.
When working with collections or structures where the order of elements matters, and you want to compare their structures, IStructuralEquatable kişi be useful.
This member is an explicit interface member implementation. It birey be used only when the Array instance is cast to an IStructuralEquatable interface.
Do not send hash codes across application domains or processes. In some cases, hash codes may be computed on a per-process or per-application domain basis.
Default property. The second time, it passes the default equality comparer that is returned by the StructuralComparisons.StructuralEqualityComparer property. The third time, it passes the custom NanComparer object. Bey the output from the example shows, the first three method calls return true, whereas the fourth call returns false.
Bunun yüzı rabıta, IStructuralComparable arayüzü, izlenceınızı daha modüler hale getirir ve kod yenidenını azaltır. Farklı muta bünyeları beyninde yapısal içinlaştırma davranışlemlerini bir bir yerde yönetebilir ve kodunuzun hizmetını kolaylaştırabilirsiniz.
