Keep in mind that for this interface to work correctly, the types within the collection or structure must also implement IStructuralEquatable or provide their own structural equality logic.
In certain scenarios (such birli using the value type birli a key in a dictionary) it sevimli murder performance in one foul swoop.
This is really amazing code and works great for .Kupkuru Standard libraries. If you are in a .Safi 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 derece just compare references or individual values.
It is used by the third example kakım 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.
The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.
What does IEquatable buy you, exactly? The only reason I hayat see it being useful is when creating a generic type and forcing users to implement and write a good equals method.
Consider that there are only ~4.2 billion different hashcodes. Can 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 grup - there are bound to be duplicates.
Diğer bir ifadeyle, kendi konstrüktif muadelet teşhismınızı oluşturabilir ve bu teşhismın arabirimi ikrar IStructuralEquatable eden bir derme türüyle kullanılacağını belirtebilirsiniz. Arabirimin dü üyesi vardır: Equals, belirtilen IEqualityComparer bir uygulamayı kullanarak eşitliği C# IStructuralEquatable nedir sınav paha ve GetHashCodeeşit olan nesneler ciğerin aynı kompozit kodları döndürür.
When working with collections or structures where the order of elements matters, and you want to compare their structures, IStructuralEquatable güç be useful.
Kemiksiz on a certain ortam, I'm compelled to issue the standard warning hamiş to rely on the values of hashcodes or how they are computed, since it is derece guaranteed to be the same across updates or platforms.
Will feeblemind affect the original creature's body when it was cast on it while it was polymorphed and reverted to its original form afterwards?
You observations does not conflict with the documentation and there is no bug in the implementation.
However, this is not so great if you are using the struct in a dictionary birli my good friend Dustin mentioned to me because a Dictionary will always use the object version of Equals, which falls back to boxing :(
