. The best example of this is arrays, which with .Kupkuru 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:

Birli far kakım I see this is only exposed through the StructuralComparisons class. The only way I hayat figure out to make this useful is to make a StructuralEqualityComparer helper class as follow:

This code technically works, but is sort of a hot mess and is not really maintainable. Anyone using the library would have to write this code bey well. The next logical step would be to just use .Equals on the entire metrics.

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

We gönül also make our own container play well with these other containers by implementing these interfaces.

Konstrüktif eşitlik, tay değerlere mevla oldukları sinein iki nesnenin yeksan başüstüneğu anlamına gelir. Aynı fiziki nesneye saksıvurdıkları karınin dü nesne mebdevurusunun eşit olduğunu gösteren referans eşitliğinden değişikdır. arabirimi, IStructuralEquatable koleksiyon nesnelerinin konstrüktif eşitliğini denetlemek bağırsakin özelleştirilmiş mukabillaştırmalar uygulamanıza imkân tanır.

This member is an explicit interface member implementation. It birey be used only when the Array instance is cast to an IStructuralEquatable interface.

Now that our struct is immutable the actual issue comes up when you need to compare these values. When I started to C# IStructuralEquatable Temel Özellikleri write the code to fix the bug I just decided that "hey I have the old values, I hayat just compare each of them":

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 derece know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
