If equality is derece needed for the derived class you dirilik 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.

. The best example of this is arrays, which with .Kemiksiz 4 now implement the IStructuralEquatable interface. This makes it possible to distinguish whether you are comparing two arrays for reference equality, or for "structural equality" - whether they have the same number of items with the same values in each position. Here's an example:

Do hamiş fear because if you simply implement IEquatable the dictionary will use the strongly typed version! The nice thing is that we kind of actually already did this! So now we just have to do this:

Let us hamiş forget about additional operators and hamiş just relying on Equals. We kişi implement the == and != operators easily:

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.

Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?

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

The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .

Being able to specify IStructuralEquatable/IStructuralComparable in such cases is actually useful. It would also be inconvenient to pass a TupleComparer or ArrayComparer everywhere you want to apply this type of comparison. The C# IStructuralEquatable Temel Özellikleri two approaches are not mutually exclusive.
