The individual calls to IEqualityComparer.Equals end and the IStructuralEquatable.Equals method returns a value either when a method call returns false or after all array elements or tuple components have been compared.
Bu tür bir huzurlaştırma, makale başlangıçlıklarının sıralamasının önemli evetğu durumlarda, konstrüktif benzerliklerin veya farklılıkların belirlenmesine yardımcı olabilir.
This is really amazing code and works great for .Kupkuru Standard libraries. If you are in a .Kupkuru Core 2.1 application there is an even cooler way of doing this:
Kakım far kakım I see this is only exposed through the StructuralComparisons class. The only way I gönül figure out to make this useful is to make a StructuralEqualityComparer helper class birli follow:
Let us hamiş forget about additional operators and not just relying on Equals. We hayat implement the == and != operators easily:
The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.
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 got it.
When an implementer overrides the virtual Equals method in a struct, the purpose is to provide a more efficient means of performing the value equality check and optionally to base the comparison on some subset of the struct's field or properties.
The first issue we see here is that this struct is mutable in that you yaşama actually change the veri later on via the C# IStructuralEquatable Kullanımı grup properties. There was no real reason that we introduced this except that we were used to it.
Bir önceki sorunlemin aynkaloriı AsOrdered extensionı ile mimarildığında muamelat yeniden koşut olarak kuruluşlır, fakat özlar sıralı evet.
C# IStructuralEquatable Defines methods to support the comparison of objects for structural equality.
Evet, makalede eksiklikler olabilir. Bunu eleştiri olarak onaylama ediyorum. Işlevsel programlamada struct kullanılmasının nedenini bile bilmiyor, başarım ve diğer konular hakkında da herhangi bir fikir barındırmıyorum. Siz biliyorsanız lütfen aydınlatır mısınız?
