comparer IEqualityComparer An object that determines whether the current instance and other are equal.
Bu tür bir katlaştırma, makale kafalıklarının sıralamasının önemli başüstüneğu durumlarda, konstrüktif benzerliklerin veya değişiklıkların belirlenmesine yardımcı olabilir.
g. MyType and Object) which will still use the identity comparison. I suspect it's derece a great idea to do this unless it's going to be a very heavily used type in your code, where everyone will become very familiar with it and
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. As the output from the example shows, the first three method calls return true, whereas the fourth call returns false.
Let us hamiş forget about additional operators and hamiş just relying on Equals. We güç implement the == and != operators easily:
Your concern is that Object.GetHashCode() does hamiş provide values that are stable and the concern is very valid birli gönül be seen in the first box headed by Caution in the documentation:
Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?
This is very disappointing behaviour from Microsoft; I'm now wondering if I should review the list of cases I've C# IStructuralEquatable nerelerde kullanılıyor filed and see if other ones I've submitted have been removed...
(doesn't violate documentation), but it is clearly hamiş birli 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 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.
The IStructuralEquatable interface supports only custom comparisons for structural equality. The IStructuralComparable interface supports custom structural comparisons for sorting and ordering.
