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.

Reference types (read classes) don't benefit birli much. The IEquatable implementation does let you avoid a cast from System.Object but that's a very trivial gain. I still like IEquatable to be implemented for my classes since it logically makes the intent explicit.

IStructuralComparable arayüzü, ekseriya Array ve Tuple kadar muta konstrüksiyonları aracılığıyla uygulanır. Bu veri konstrüksiyonları, elemanlarının sıralamasını ve yapısını dikkate alarak katlaştırma yapar.

It is used by the third example bey an argument to the Equals(Object, IEqualityComparer) method of the IStructuralEquatable interface that tuples implement. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.

The following example defines a NanComparer class that implements the IStructuralEquatable interface. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.

This member is an explicit interface member implementation. It yaşama be used only when the Array instance is cast to an IStructuralEquatable interface.

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 not conflict with the documentation and there is no bug in the implementation.
