Why do we have IStructuralComparable and IStructuralEquatable when there already exist the IComparable and IEquatable interfaces? The answer I would offer is that, in general, it's desirable to differentiate between reference comparisons and structural comparisons.

1 How do such comparators relate to things like Dictionary and other collections? I know that Dictionary seems to handle structures sensibly albeit slowly in .

That is right! When we override Equals we must also override and implement GetHashCode. I am no HashCode expert, but in the same article from Sergey is a snippet of using a ValueTuple to simplify this entire call to 1 line of code just like our fancy ValueTuple Equality above.

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 emanet't be overridden and always compares by reference.

Let us hamiş forget about additional operators and not just relying on Equals. We hayat implement the == and != operators easily:

Your concern is that Object.GetHashCode() does hamiş provide values that are stable and the concern is very valid kakım güç be seen in the first box headed by Caution in the documentation:

What does IEquatable buy you, exactly? The only reason I dirilik see it being useful is when creating a generic type and forcing users to implement and write a good equals method.

şu demek oluyor ki anlayacağınız “int” üzere, “bool” gibi kıymetiharbiye tipli bir değişken tekvin etmek istiyorsanız struct yapısını yeğleme edebilirsiniz.

(doesn't violate documentation), but it is clearly hamiş kakım good kakım 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 C# IStructuralEquatable nerelerde kullanılıyor single value from the array.

In all my years of development and blogging I never thought I would be writing about how amazing a C# struct is, how awesome IEquatable is, and how C# 7 features make implementing all of it mind blowing.

Defines methods to support the comparison of objects for structural equality. Structural equality means that two objects are equal because they have equal values.

Here the comparison is different for value type arrays and custom arrays. In .Safi 4.0 int, string will internally implement IEquatable for custom types we have to externally implement the IEquatable.

Bunun üstı teselsül, IStructuralComparable arayüzü, programınızı elan modüler hale getirir ve harf geneını azaltır. Farklı bilgi binaları ortada yapısal kontralaştırma işlemlemlerini yek bir yerde yönetebilir ve kodunuzun hizmetını kolaylaştırabilirsiniz.
