Hakkında herşey C# IStructuralEquatable Nasıl kullanılır

If equality is not needed for the derived class you yaşama skip IEquatable but you need to override the CanEqual to prevent it being equal with base classes (unless of course they should be considered equal).

In this case you don't want to change your class implementation so you don't wantoverride the Equals method. this will define a general way to compare objects in your application.

It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

IStructuralComparable arayüzü, çoklukla Array ve Tuple üzere done bünyeları aracılığıyla uygulanır. Bu data mimariları, elemanlarının sıralamasını ve yapısını dikkate alarak muhaliflaştırma yapar.

Birli an example, it might make sense for two different instances of an Employee class to be considered equal if they both represent the same entity in your system.

Structural equality means that two objects are equal because they have equal values. It differs from reference equality, which indicates that two object references are equal because they reference the same physical object. The IStructuralEquatable interface enables you to implement customized comparisons to check for the C# IStructuralEquatable Temel Özellikleri structural equality of collection objects.

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

When an implementer overrides the virtual Equals method in a struct, the purpose is to provide a more efficient means of performing the value equality check and optionally to base the comparison on some subset of the struct's field or properties.

Başka bir ifadeyle, kendi strüktürel muadelet tanımınızı oluşturabilir ve bu tanılamamın arabirimi kabul IStructuralEquatable eden bir derlem türüyle kullanılacağını belirtebilirsiniz. Arabirimin dü üyesi vardır: Equals, tamlanan IEqualityComparer bir uygulamayı kullanarak eşitliği sınav fiyat ve GetHashCodeeşit olan nesneler dâhilin aynı muhtelit kodları döndürür.

When working with collections or structures where the order of elements matters, and you want to compare their structures, IStructuralEquatable dirilik be useful.

Safi on a certain ortam, I'm compelled to issue the standard warning not to rely on the values of hashcodes or how they are computed, since it is hamiş guaranteed to be the same across updates or platforms.

Defines methods to support the comparison of objects for structural equality. Structural equality means that two objects are equal because they have equal values.

You observations does hamiş conflict with the documentation and there is no bug in the implementation.
