I have a method:
private void DeletePuzzle(object param)
{
}
param is a System.Windows.Controls.SelectedItemCollection, that I got from a WPF ListView's SelectedItems property.
Somehow, I can't seem to cast it from an object to anything useful. I can't create a System.Windows.Controls.SelectedItemCollection because of its protection level, and param won't cast to IList, ICollection or IEnumerable.
How can I iterate through param's items?
