Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:

The IStructuralComparable interface supports only structural comparisons for sorting or ordering. The IStructuralEquatable interface supports custom comparisons for structural equality.

StructuralComparisons klasını kullanarak, yalnız bilgi gestaltlarının katlaştırmasını bileğil, aynı zamanda bu data kuruluşlarının muadelet kontrollerini de kolay gerçekleştirebiliriz.

The IStructuralComparable interface enables you to implement customized comparisons for collection members. That is, you güç define precisely what it means for one collection object to precede, follow, or occur in the same position in the sort order birli a second collection object.

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.

Note that the example does not directly call the CompareTo method. The method is called implicitly by the Sort(Array, IComparer) method for each tuple object in the array.

CompareTo(Object, IComparer), its Compare C# StructuralComparisons Kullanımı 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:

If the first item in the comparison gönül be cast to an IStructuralEquatable object (in other words, if it is a collection object that implements C# StructuralComparisons Temel Özellikleri the IStructuralEquatable interface), it calls the IStructuralEquatable.Equals method.

Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals gönül't be overridden and always compares by reference.
