The "No" in part 2 of the answer is actually incorrect. Note: Tried editing the answer, but apparently some think that the highest rated answer being incorrect is not reason enough to approve a correction edit.
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.
Yazgımızın yukarıdaki satırlarında da bahsettiğimiz gibi struct C#’ta value type yaratabileceğimiz mimaridır.
Ee kavil gelimi struct yapısında da new işletmenünü kullanırsak şayet ha müteallik dokumadan bir nesne üretilecektir amma struct bir porte tipli değişebilir yapısında evetğundan dolayı o nesne belleğin Stack kısmında korunum edilecektir.
The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation kakım an argument to the Equals method, you sevimli define a custom equality comparison for the array or collection.
So, I am apparently wrong birli unequal objects may have equal hash codes. But isn't GetHashCode returning a somewhat randomly distributed takım of values a requirement?
In my implementation I delegated the task of calculating hash codes to the internal array. While testing it, to my great surprise, I found that my two different arrays had the same structural hash code
The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .
In Xamarin.Essentials we use the C# struct all over the place to encapsulate "small groups of related variables" for our event handlers. They are groups of data that don't need to be created by the developers consuming the data and are only really used for reading the data.
Safi on a certain platform, I'm compelled to issue the standard warning derece to rely on the values of hashcodes or how they are computed, since it is hamiş guaranteed to be the same across updates or platforms.
Do hamiş send hash codes across application domains or processes. In some cases, hash codes may be computed on a per-process or per-application domain basis.

Being able to specify IStructuralEquatable/IStructuralComparable in such cases is actually useful. It would also be inconvenient to pass a TupleComparer or ArrayComparer everywhere you want to apply this type of comparison. The two approaches are derece mutually exclusive.
