Bey it was implemented, you compare collections using IStructuralComparable, which requires you to pass in an IComparer to use in comparing individual elements from the two structures. Since IComparer and IStructuralComparable are two different interfaces, you have problems if the elements of the IStructuralComparable are themselves collections, which now get compared with IComparer.

g. it would perhaps use the depth of the trees birli a way to order them.) I'll try to draw an example picture of this but I suspect someone may already have one and will post it before I have the chance.

Referans tipidir. Bu, bir dershane nesnesini sair bir nesneye atadığınızda, her iki nesnenin bile aynı veriye bir referansı olduğu manaına hasılat.

. The best example of this is arrays, which with .Safi 4 now implement the IStructuralEquatable interface. This makes it possible to distinguish whether you are comparing two arrays for reference equality, or for "structural equality" - whether they have the same number of items with the same values in each position. Here's an example:

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 as a second collection object.

Being able to specify IStructuralEquatable/IStructuralComparable in such cases is actually useful. It would also be inconvenient to pass a TupleComparer or ArrayComparer everywhere you want to apply this type of comparison. The two approaches are derece mutually exclusive.

Yöntemin bu uygulaması, bir derlem nesnesinin Compare her öğesini başka bir derlem nesnesinin ilgili öğesiyle zıtlaştırdığında kötüdaki kabil davranır:

GetHashCode Metodu: C# StructuralComparisons Temel Özellikleri Nesnenin strüktürel özelliklerine dayalı olarak bir hash kodu üretir. Bu, koleksiyonların hızlı bir şekilde içinlaştırılmasını sağlar.

My C# StructuralComparisons Kullanımı understanding is that it's used for collection like types, and C# StructuralComparisons Temel Özellikleri 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)

The interface özgü a single member, CompareTo, which determines whether the current collection object is less than, equal to, or greater than a second object in the sort order.

ianhays commented Oct 23, 2017 Definitely agree that the implementation above would be too slow. Could we instead just write a new StructuralComparer that didn't call to the nongeneric StructuralComparisons.StructuralEqualityComparer?

ghost commented Oct 26, 2021 Due to lack of recent activity, this issue özgü been marked bey a candidate for backlog cleanup. It will be closed if no further activity occurs within 14 more days. Any new comment (by anyone, hamiş necessarily the author) will undo this process.
