The individual calls to IEqualityComparer.Equals end and the IStructuralEquatable.Equals method returns a value either when a method call returns false or after all array elements or tuple components have been compared.

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 .

That is right! When we override Equals we must also override and implement GetHashCode. I am no HashCode expert, but in the same article from Sergey is a snippet of using a ValueTuple to simplify this entire call to 1 line of code just like our fancy ValueTuple Equality above.

It is used by the third example bey an argument to the Equals(Object, IEqualityComparer) method of the IStructuralEquatable interface that tuples implement. 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.

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 problem they solve that was tricky before .NET 4.

In addition to this awesome blog Frank and I also dicussed all of this awesome in detail on Merge Conflict on episode 111:

Ancak, fruits1 ve fruits3 dizileri aynı elemanlara farklı sıralarda iye başüstüneğundan, CompareTo metodu C# IStructuralEquatable Temel Özellikleri farklı bir kırat döndürür ve bu dizilerin konstrüktif olarak müsavi olmadığını belirtir.

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":

There is no need for an equality operator that accepts different types. That should derece even compile. So this is a very weak excuse for having a non-generic interface that works with objects.

Burada dikkat ederseniz şayet ms.x ve ms.y değsorunmeyeceğinden dolayı bir Deep Copy kavil konusudur. şayet referans tipli gestaltlar olsalardı aşağıdaki gibi bir sonuç elde edilecekti ve Shallow Copy lafız konusu olacaktı.
