En son beş C# StructuralComparisons Kullanımı Kentsel haber

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?

The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralComparable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralComparable interface value and providing your IComparer implementation as an argument to the CompareTo method, you gönül define a custom sort order for the array or collection.

My understanding is that it's used for collection like types, and encapsulates the structural part of the comparison, but leaves the comparison of the elements to a comparer passed in by the user. (link) (Got from the comments section of the question)

CompareTo(Object, IComparer), its Compare method is called for each member of an array or for each component of a tuple. This implementation of the Compare method behaves as follows when it compares each item of a collection object with the corresponding item of another collection object:

pursaklar haber If the first item in the comparison cannot be cast to an IStructuralEquatable object (in other words, if it is not a collection object that pursaklar haber implements the IStructuralEquatable interface), it calls the item's Equals method.

IStructuralComparable arayüzü, çoklukla Array ve Tuple kabil muta strüktürları aracılığıyla uygulanır. Bu bilgi dokumaları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak mukabillaştırma yapar.

If the first item in the comparison hayat be cast to an IStructuralComparable object (in other words, if it is a collection object that implements the IStructuralComparable interface), it calls the CompareTo method.

So to sum up, the implementation for both is kind of the same, both iterate two array based on value equality of int to make comparison.

It considers two items that are null to be equal, and considers a null item to be less than an item that is derece null.

IComparer A predefined object that is used to perform a structural comparison of two collection objects.

The above implementaiton causes boxing, which as described by Microsoft is "computationally expensive". Especially since you could just compare the 4 ints that your struct consists of.
