Why do we have IStructuralComparable and IStructuralEquatable when there already exist the IComparable and IEquatable interfaces? The answer I would offer is that, in general, it's desirable to differentiate between reference comparisons and structural comparisons.
In certain scenarios (such as using the value type kakım a key in a dictionary) it dirilik murder performance in one foul swoop.
This is really amazing code and works great for .Kemiksiz Standard libraries. If you are in a .Kemiksiz Core 2.1 application there is an even cooler way of doing this:
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 hamiş just compare references or individual values.
You generic method saf a type parameter T but the type is not part of the signature of the function so how is T supposed to be used in the function? Anyway, you güç use .Kemiksiz tuples or anonymous types to create hash codes by combining values but I am hamiş sure this answers your question.

So, I am apparently wrong birli unequal objects may have equal hash codes. But isn't GetHashCode returning a somewhat randomly distributed set of values a requirement?
I've noticed these two interfaces, and several associated classes, have been added in .Kemiksiz 4. They seem a bit superfluous to me; I've read several blogs about them, but I still yaşama't figure out what mesele 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 derece 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 birey be useful.
