IEqualityComparer Konstrüktif muadelet midein dü koleksiyon nesnesini alınlaştırmak bâtınin kullanılan önceden teşhismlanmış bir nesne.

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

. The best example of this is arrays, which with .Kupkuru 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:

However, you do derece call the CompareTo method directly in most cases. Instead, the CompareTo method is called by sorting methods such as Sort(Array, IComparer). In this case, you define your IComparer implementation and pass it birli an argument to a sorting method or collection object's class constructor. The CompareTo method with your custom comparer is then called automatically whenever the collection is sorted.

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 not mutually exclusive.

Yukarıdaki kodda, dizi1 ve dizi2 isimli iki sekans oluşturulmuşdolaşma. Her dü dizinin de elemanları tıpkıdır. Şimdi, bu dizileri StructuralComparer kullanarak içinlaştıracağız:

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

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

Koleksiyonların Konstrüktif Hakkındalaştırması: IStructuralEquatable arabirimi, özellikle diziler ve koleksiyonlar üzere konstrüktif done dokumalarının önlaştırılması midein kullanılır.

And bey a result, default equality checks need two of the compared items to be the same type but StructuralEqualityComparer doesn't require them C# StructuralComparisons Temel Özellikleri to be same type. As the name suggests it is supposed to compare contents.

What does redirecting stderr interfere with bash's handling of $COLUMNS and the `checkwinsize` option?

So, the main difference between C# StructuralComparisons Temel Özellikleri two methods is the equality check method they use. SequenceEqual uses IEquatable interface method for checks, and StructuralComparisons.StructuralEqualityComparer uses IStructuralEquatable interface method for checks.
