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.
In certain scenarios (such kakım using the value type bey a key in a dictionary) it yaşama murder performance in one foul swoop.
The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.
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.

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.
IStructuralEquatable is quite new and unknown, but I read somewhere that it hayat be used to compare the contents of collections and arrays. Am I wrong, or is my .Safi wrong?
I've noticed these two interfaces, and several associated classes, have been added in .Kupkuru 4. They seem a bit superfluous to me; I've read several blogs about them, but I still sevimli't figure out what sorun they solve that was tricky before .Kemiksiz 4.

Task oluşturmanın konulemci üzerinde maliyeti vardır ve çok kısaltarak devam eden medarımaişetlemler için bir task peyda etmek genelde henüz yavaş çkızılışan C# IStructuralEquatable nedir uygulamalara vesile evet.
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.
The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.
There is no need for an equality operator that accepts different types. That should not even compile. So this is a very weak excuse for having a non-generic interface that works with objects.
Specifically, I do hamiş know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
