It's normally expected that if you implement IEquatable.Equals you will also override Object.Equals to be consistent. In this case how would you support both reference and structural equality?

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 .

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

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and not just compare references or individual values.

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

Consider that there are only ~4.2 billion different hashcodes. Hayat you create more than this many different objects of the type on which GetHashCode is called? In this case it is easy to see the answer is "yes". So GetHashCode is a sort of compressing projection onto a smaller set - there are bound to be duplicates.

The first issue we see here is that this struct is mutable in that you yaşama actually change the data later on via the grup properties. There was no real reason that we introduced this except that we were used to it.

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 emanet just compare each of them":

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