It's normally expected that if you implement IEquatable.Equals you will also override Object.Equals to be consistent. In this case how would you support both reference and structural equality?

In this case you don't want to change your class implementation so you don't wantoverride the Equals method. this will define a general way to compare objects in your application.

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:

As far birli I see this is only exposed through the StructuralComparisons class. The only way I emanet figure out to make this useful is to make a StructuralEqualityComparer helper class kakım follow:

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.

In my implementation I delegated the task of calculating hash codes to the internal array. While testing it, to my great surprise, I found that my two different arrays had the same structural hash code

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 two approaches are not mutually exclusive.
