Hi all,

Hi,

I do not undesrtand what you're trying to achieve, but here's a way to create a new SelectionSet instance with the same objectIds in reveresd order. But you have to keep in mind the order of selected onjects in a selection set is not reliable.

var objectIds = selection.Value.GetObjectIds();
var reversedObjectIds = objectIds.Reverse().ToArray();
var reversedSelection = SelectionSet.FromObjectIds(reversedObjectIds);

Thank you!
