If the first item in the comparison cannot be cast to an IStructuralEquatable object (in other words, if it is derece a collection object that implements the IStructuralEquatable interface), it calls the item's Equals method.

Birli it was implemented, you compare collections using IStructuralComparable, which requires you to pass in an IComparer to use in comparing individual elements from the two structures. Since IComparer and IStructuralComparable are two different interfaces, you have problems if the elements of the IStructuralComparable are themselves collections, which now get compared with IComparer.

The IStructuralComparable interface supports only structural comparisons for sorting or ordering. The IStructuralEquatable interface supports custom comparisons for structural equality.

The PopulationComparer class provides an IComparer implementation that allows the array of sextuples to be sorted by any one of its components. Two values are provided to the PopulationComparer class in its constructor: the position of the component that defines the sort order, and a Boolean value that indicates whether the tuple objects should be sorted in ascending or descending order.

The actual comparison of the members or elements in the current instance with those in a second object is performed by an IComparer interface implementation, which contains the definition of your custom comparison.

ianhays commented Oct 23, 2017 Definitely agree that the implementation above would be too slow. Could we instead just write a new StructuralComparer that didn't call to the nongeneric StructuralComparisons.StructuralEqualityComparer?
