However, you do hamiş call the CompareTo method directly in most cases. Instead, the CompareTo method is called by sorting methods such bey Sort(Array, IComparer). In this case, you define your IComparer implementation and pass it kakım an argument to a sorting method or collection object's class constructor. The CompareTo method with your custom comparer is then called automatically whenever the collection is sorted.

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 hamiş mutually exclusive.

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects. This is also made clear by the fact that this interface resides in the System.Collections namespace.
