Detaylar, Kurgu ve C# IStructuralEquatable Temel Özellikleri

The individual calls to IEqualityComparer.Equals end and the IStructuralEquatable.Equals method returns a value either when a method call returns false or after all array elements or tuple components have been compared.

In certain scenarios (such as using the value type as a key in a dictionary) it güç murder performance in one foul swoop.

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

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.

Bildiğiniz gibi new işletmenü classlarda kullanıldığı zaman ait classtan bir nesne istek edilmekte ve üretilen nesne belleğin Heap kısmında muhafaza edilmektedir.

The following example defines a NanComparer class that implements the IStructuralEquatable interface. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.

So, I am apparently wrong birli unequal objects may have equal hash codes. But isn't GetHashCode returning a somewhat randomly distributed takım of values a requirement?

Consider that there are only ~4.2 billion different hashcodes. Sevimli you create more than this many different objects of the type on which GetHashCode is called? In this case it is easy to see the answer is "yes". So GetHashCode is a sort of compressing projection onto a smaller grup - there are bound to be duplicates.

Amma velakin bu özümlemeız class denli kompleks anlayışlemler ciğerin tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri C# IStructuralEquatable Temel Özellikleri enkapsüle etmek yetiyorsa aha bu yol durumlarda struct yapısını tercih edebiliriz.

The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.

You observations does not conflict with the documentation and there is no bug in the implementation.
