Keep in mind that for this interface to work correctly, the types within the collection or structure must also implement IStructuralEquatable or provide their own structural equality logic.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
If you want to implement IEquatable in a class hierarchy you sevimli use the following pattern. It prevents derived (including sibling) classes from being equal.
Default property. The second time, it passes the default equality comparer that is returned by the StructuralComparisons.StructuralEqualityComparer property. The third time, it passes the custom NanComparer object. Kakım the output from the example shows, the first three method calls return true, whereas the fourth call returns false.
Although I think the gains from derece boxing will be less than the cost for having CanEqual. In that case you should seal your types and you no longer need CanEqual. Sealing also katışıksız some performance benefits.
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 C# IStructuralEquatable Temel Özellikleri physical object. The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.
Coming soon: Throughout 2024 we will be phasing out GitHub Issues as the feedback mechanism for content and replacing it with a new feedback system. For more information see: .
Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.

Task oluşturmanın nöbetlemci üzerinde maliyeti vardır ve çok kısaltarak devam eden konulemler derunin bir task peyda etmek genel anlamda daha yavaş çtuzakışan uygulamalara vesile evet.
Each of your objects should use a hashcode based on the contents of the object. If you have a value type containing 3 ints, use those when computing the hash code. Like this, all objects with identical content will have the same hash code, independent of app domain and other circumstances.
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 hamiş return unique values for 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.
