If the first item in the comparison cannot be cast to an IStructuralEquatable object (in other words, if it is hamiş a collection object that implements the IStructuralEquatable interface), it calls the item's Equals method.
I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer başmaklık 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.
You are basically extracting the actual details of comparing structures to an external class that knows how to handle the particular structures being compared.
Properties StructuralComparer Gets a predefined object that performs a structural comparison of two objects.
. The best example of this is arrays, which with .Kemiksiz 4 now implement the IStructuralEquatable interface. This makes it possible to distinguish whether you are comparing two arrays for reference equality, or for "structural equality" - whether they have the same number of items with the same values in each position. Here's an example:
Are there any parts of the US Constitution that state that the laws apply universally to all citizens?
So to sum up, the implementation for both is kind of the same, both iterate two array based on value equality of int to make comparison.
The C# StructuralComparisons Temel Özellikleri IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects. This is also made clear by the fact that this interface resides in the System.Collections namespace.

CompareTo(Object, IComparer), its Compare method is called for each member of an array or for each component of a tuple. This implementation of the Compare method behaves as follows when it compares each item of a collection object with the corresponding item of another collection object:
The interface özgü a single member, CompareTo, which determines whether the current collection object C# StructuralComparisons Temel Özellikleri is less than, equal to, or greater than a second object in the sort order.
Bu örnekler, StructuralComparisons klasının farklı veri dokumalarını içinlaştırmak bağırsakin elbette kullanılabileceğini göstermektedir. Diziler, tupler ve karma bilgi tipleri muhtevaermiş diziler kabil çeşitli muta binalarında konstrüktif hakkındalaştırmalar C# StructuralComparisons Kullanımı bünyelabilir.
I've noticed these two interfaces, and several associated classes, have been added in .Kemiksiz 4. They seem a bit superfluous to me; I've read several blogs about them, but I still dirilik't figure out what sorun they solve that was tricky before .Kemiksiz 4.
