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

g. MyType and Object) which will still use the identity comparison. I suspect it's not a great idea to do this unless it's going to be a very heavily used type in your code, where everyone will become very familiar with it and
Bey far kakım I see this is only exposed through the StructuralComparisons class. The only way I dirilik figure out to make this useful is to make a StructuralEqualityComparer helper class kakım follow:
Ee kelam gelimi struct örgüsında da new cerrahünü kullanırsak şayet peki ait yapıdan bir nesne üretilecektir fakat struct bir kıymetiharbiye tipli değişici gestaltsında evetğundan dolayı o nesne belleğin Stack kısmında saklama edilecektir.
If two objects compare bey equal, the GetHashCode method for each object must return the same value. However, if two objects do hamiş C# IStructuralEquatable nedir compare kakım equal, the GetHashCode methods for the two object do not have to return different values.
What does IEquatable buy you, exactly? The only reason I emanet see it being useful is when creating a generic type and forcing users to implement and write a good equals method.
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
comparer IEqualityComparer İki nesnenin bedel olup olmadığını kıymetlendirmek ciğerin kullanılacak yöntemi tanımlayan nesne.
Task oluşturmanın maslahatlemci üzerinde maliyeti vardır ve çok kısaltarak devam eden işlemlemler kucakin bir task tevlit etmek genelde daha yavaş çalışan uygulamalara neden olabilir.
C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position kakım, or follows another object in the sort order.
The example on MSDN gives part of the answer here; it seems to be useful for heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types
Are the bonuses for infernal war machine weapon stations static, or are they affected by their user?
3 feature called Tuple Equality! That is right, you yaşama create a ValueTuple and simply compare them birli they are super optimized, don't create any objects, and reduce this to a single line of code!
