推荐答案

通常，如果我这样做，我会维护两个ObservableCollections，一个绑定到第一个ListBox，第二个绑定到第二个列表框。然后，当我想在ListBox之间移动项目时，我会从第一个ObservableCollection中删除该项目并将其添加到第二个ObservableCollection中。移动的外观是通过绑定的魔力自动处理的，然后我会对ObservableCollection中的实际元素进行处理，而不是试图破解回ListBox。

Normally, if I were doing something like this, I would maintain two ObservableCollections, one bound to the first ListBox and the second bound to the second ListBox. Then, when I wanted to move items between the ListBoxes, I would remove the item from the first ObservableCollection and add it into the second ObservableCollection. The appearance of moving is handled automatically through the magic of binding and I would then do processing against the actual elements in the ObservableCollection, rather than trying to hack back into the ListBox.
