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.
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 .
Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:
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 güç't be overridden and always compares by reference.
Birli an example, it might make sense for two different instances of an Employee class to be considered equal if they both represent the same entity in your system.
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 not really sure if I really got it.
Coming soon: Throughout 2024 we will be phasing out GitHub Issues as the feedback mechanism for content and replacing it with a new feedback system. For more information see: .
Diğer bir ifadeyle, kendi konstrüktif müsavat teşhismınızı oluşturabilir ve bu tanımın arabirimi kabul IStructuralEquatable eden bir koleksiyon türüyle kullanılacağını belirtebilirsiniz. Arabirimin iki C# IStructuralEquatable Temel Özellikleri üyesi vardır: Equals, belirtilen IEqualityComparer bir uygulamayı kullanarak eşitliği test değer ve GetHashCodeeşit olan nesneler muhtevain aynı muhtelit kodları döndürür.
In addition to this awesome blog Frank and I also dicussed all of this awesome in detail on Merge Conflict on episode 111:
Kemiksiz on a certain ortam, I'm compelled to issue the standard warning not to rely on the values of hashcodes or how they are computed, since it is derece guaranteed to be the same across updates or platforms.
Ha, makalede nekais kabil. Bunu tenkit olarak akseptans ediyorum. Işlevsel programlamada struct kullanılmasının nedenini de bilmiyor, başarım ve sair konular üzerine da herhangi bir kuruntu barındırmıtefsir. Siz biliyorsanız lütfen aydınlatır mkaloriız?
The IStructuralEquatable interface supports only custom comparisons for structural equality. The IStructuralComparable interface supports custom structural comparisons for sorting and ordering.
