I.m trying to understand Drag and Drop, and so studying someones code.
I have a question about the following code:


     private void DragStarted(ItemsControl itemsControl)

            DataObject dObject = new DataObject(ItemType, _data);
            DragDropEffects e =  DragDrop.DoDragDrop(itemsControl, dObject, DragDropEffects.Copy | DragDropEffects.Move);
            if ((e & DragDropEffects.Move) != 0)


can someone explain why:
 ((e & DragDropEffects.Move) != 0) is used

and not just

 (e  != 0)
