C# IStructuralEquatable Kullanımı Temel Açıklaması

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.

This is really amazing code and works great for .Kupkuru Standard libraries. If you are in a .Kupkuru Core 2.1 application there is an even cooler way of doing this:

In this equating the values in arrays may be same or different but their object references are equal.

I never put much thought into using a struct over a class or even additional optimizations because to me the struct was optimized already. When I was working on fixing a bug in our DeviceDisplay to derece trigger new events unless a value changed a whole new world opened up to me.

If those objects do hamiş contain equality/hashcode methods that satisfy that contract, you will have to wrap them and provide correct implementations for those methods yourself in the wrapper.

Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.

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.

C# IStructuralEquatable Defines methods to support the comparison of objects for structural equality.

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

There is no need for an equality operator that accepts different types. C# IStructuralEquatable Kullanımı 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.
