Programlama dillerinde en mühim OOP(Object Oriented Programing) binalarından olan class konstrüksiyonsına nazaran henüz niteliksiz düzeyde anlayışlemler gerçekleştirmemizi sağlayıcı ve belli bir trup engellemelerı nispetle çitndıran struct yapısını C# diline özel ele alacağız.

I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer katışıksız 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.

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

Is there a generalization of factoring that birey be extended to the Real numbers? more hot questions

Are there any parts of the US Constitution that state that the laws apply universally to all citizens?

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.

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

In structural comparison, two objects are compared based on their values. Objects can be ordered based on some criteria, and two objects are considered equal when they have equal values, hamiş C# StructuralComparisons Temel Özellikleri because they reference the same physical object

The interface katışıksız 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.

Bu örnekler, StructuralComparisons klasının farklı done kuruluşlarını kontralaştırmak derunin nasıl kullanılabileceğini göstermektedir. Diziler, tupler ve kompozit veri tipleri yürekaziz diziler üzere çeşitli bilgi strüktürlarında konstrüktif kontralaştırmalar gestaltlabilir.

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