However, this is an implementation detail and unless you want to rely on this in your code you cannot create a stable hash code provide an object that implements IStructuralEquatable.

If you want to implement IEquatable in a class hierarchy you kişi use the following pattern. It prevents derived (including sibling) classes from being equal.

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and hamiş just compare references or individual values.

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 kişi 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.

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