C# IStructuralEquatable nedir Için Adım Haritaya göre Yeni Adım

Wiki Article

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.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

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

Does anyone know what happens if you do hamiş implement iequtalable when using generic collections? 2

Bildiğiniz gibi new operatrisü classlarda kullanıldığı vakit müntesip classtan bir nesne dileme edilmekte ve üretilen nesne belleğin Heap kısmında saklama edilmektedir.

The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation bey an argument to the Equals method, you sevimli define a custom equality comparison for the array or collection.

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.

If you read this entire post and are thinking wow that is a lot of code and steps to remember then do hamiş fear because Dustin told me and showed me that Visual Studio will generate all of this for you!!!!! Check this out:

This member is an explicit interface member implementation. C# IStructuralEquatable Temel Özellikleri It hayat be used only when the Array instance is cast to an IStructuralEquatable interface.

Now that our struct is immutable the actual issue comes up when you need to compare these values. When I started to write the code to fix the bug I just decided that "hey I have the old values, I güç just compare each of them":

There is no need for an equality operator that accepts different types. That should not even compile. So this is a very weak excuse for having a non-generic interface that works with objects.

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.
