Açıklaması C# IStructuralEquatable Nasıl kullanılır Hakkında 5 Basit Tablolar

If equality is derece needed for the derived class you birey skip IEquatable but you need to override the CanEqual to prevent it being equal with base classes (unless of course they should be considered equal).

= to provide value equality checks (vs the default reference equality check). The MSDN documentation suggests you only do it for immutable types. There are also issues involving interfaces and operator overloading.

Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:

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 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 birli an argument to the Equals method, you can define a custom equality comparison for the array or collection.

After some more testing I found that any two arrays with the same first element have the same hash. I still think this is strange behavior.

We can also make our own container play well with these other containers by implementing these interfaces.

(doesn't violate documentation), but it is clearly derece kakım good bey it would be if 0 were replaced with i. Also there's no reason to loop if the code were just going to use a single value from the array.

When working with collections or structures where the order of elements matters, and you want to compare their structures, IStructuralEquatable sevimli be useful.

Defines methods to support the comparison of objects for structural equality. Structural equality means that two objects are equal because they have equal values.
