你可以处理这两个事件：
Control.MouseEnter Event（System.Windows.Forms） [ ^ ]，>
Control.MouseLeave Event （System.Windows.Forms） [ ^ ]。
在Forms中称为悬停的替代行为是不同的：当鼠标光标在控制区域内停留一段时间时调用它。我会避免使用它，因为用户的感觉不确定，但如果你想要这个，你可以处理 Control.MouseHover事件（System.Windows.Forms） [ ^ ]。-SA
You can handle these two events:
Control.MouseEnter Event (System.Windows.Forms)[^],
Control.MouseLeave Event (System.Windows.Forms)[^].
Alternative behavior called "hovering" in Forms is different: it is invoked when a mouse cursor rests inside the control area for certain period of time. I would avoid using it, due to this uncertainty to the user's feeling, but if you want this, you can handle Control.MouseHover Event (System.Windows.Forms)[^].—SA
