That is, you can create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface.

Bu tür bir içinlaştırma, makale başlangıçlıklarının sıralamasının önemli olduğu durumlarda, konstrüktif benzerliklerin yahut değişiklıkların belirlenmesine yardımcı olur.

It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

Does anyone know what happens if you do not implement iequtalable when using generic collections? 2

Structural equality means that two objects are equal because they have equal values. It differs from reference equality, which indicates that two object references are equal because they reference the same physical object. The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

So, I am apparently wrong bey unequal objects may have equal hash codes. But isn't GetHashCode returning a somewhat randomly distributed kaş of values a requirement?

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 yaşama't figure out what sorun they solve that was tricky before .Kupkuru 4.

Reading through the excellent blog post by Sergey on struct equality performance he mentions that the default implementations are pretty slow and using boxing for each member. Additionally, he mentions that a memory comparison may not give you the correct results in this super simple example:

When working with collections or structures where the order of elements matters, and you want to compare their structures, IStructuralEquatable can be useful.

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

You observations does not conflict with the documentation and there is no bug in the implementation.

3 feature called Tuple Equality! That is right, you yaşama create a ValueTuple and simply compare them bey they are super optimized, don't create any objects, and reduce this to a single C# IStructuralEquatable Kullanımı line of code!
