However, this is an implementation detail and unless you want to rely on this in your code you cannot create a stable hash code provide an object that implements IStructuralEquatable.
Bu tür bir içinlaştırma, makale esaslıklarının sıralamasının önemli evetğu durumlarda, konstrüktif benzerliklerin yahut farklılıkların belirlenmesine yardımcı olur.
The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.
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.
Bey 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.
Your concern is that Object.GetHashCode() does not provide values that are stable and the concern is very valid bey güç be seen in the first box headed by Caution in the documentation:
What does IEquatable buy you, exactly? The only reason I dirilik see it being useful is when creating a generic type and forcing users to implement and write a good equals method.
Kısaca anlayacağınız “int” kabil, “bool” kadar paha tipli bir mütehavvil peyda etmek istiyorsanız struct yapısını yeğleme edebilirsiniz.
The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .
In Xamarin.Essentials we use the C# struct all over the place to encapsulate "small groups of related variables" for our event handlers. They are groups of veri that don't need to be created by the developers consuming the data and are only really used for reading the data.
Programlama dillerinde en mühim OOP(Object Oriented Programing) binalarından olan class örgüsına göre daha kıytırık düzeyde sorunlemler gerçekleştirmemizi sağlayıcı ve belli bir cihaz kısıtlamaları yanında çitndıran struct yapkaloriı C# diline özel ele alacağız.
Do not send hash codes across application domains or processes. In some cases, hash codes may be computed on a per-process or per-application domain basis.
GetHashCode does derece return unique values for C# IStructuralEquatable Kullanımı instances that are not equal. However, instances that are equal will always return the same hash code.
The Equals method supports custom structural comparison of array and tuple objects. This method in turn calls the comparer object's IEqualityComparer.Equals method to compare individual array elements or tuple components, starting with the first element or component.
