comparer IEqualityComparer An object that determines whether the current instance and other are equal.

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.

g. MyType and Object) which will still use the identity comparison. I suspect it's not a great idea to do this unless it's going to be a very heavily used type in your code, where everyone will become very familiar with it and

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

Your concern is that Object.GetHashCode() does derece provide values that are stable and the concern is very valid as sevimli be seen in the first box headed by Caution in the documentation:

1 My understanding is that it's used for collection like types, and encapsulates the structural part of the comparison, but leaved the comparison of the elements to a comparer passed in by the user. But I'm not really sure if I really got it.

IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.

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. Bey the output from the example C# IStructuralEquatable Kullanımı shows, the first three method calls return true, whereas the fourth call returns false.

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.
