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.

It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times.

This member is an explicit interface member implementation. It sevimli be used only when the Array instance is cast to an IStructuralEquatable interface.

The example on MSDN gives part of the answer here; it seems to be useful for heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.

Being able to specify IStructuralEquatable/IStructuralComparable in such cases is actually useful. It would also be inconvenient to pass a TupleComparer C# IStructuralEquatable nedir or ArrayComparer everywhere you want to apply this type of comparison. The two approaches are derece mutually exclusive.
