推荐答案

查看 Form.FormClosing事件 [ ^ ]或覆盖Dispose方法并在那里进行。



就个人而言，我会选择FormClosing事件，因为Dispose调用可能不会发生数小时或数周表格关闭后。

Look at the Form.FormClosing event[^] or override the Dispose method and do it there.

Personally, I would go for the FormClosing event because the Dispose call may not happen for hours or weeks after the form has been closed.
