推荐答案

您需要使用文本框的MouseEnter和MouseLeave事件在文本框中进行更改.据我记得，当鼠标进入文本框时，您想在MouseEnter事件中更改边框颜色，并在MouseLeave事件中将其设置回其先前的状态.

但是textbox类没有边框颜色属性，因此您必须创建自己的自定义控件并从那里(而不是从textbox类中)调整文本框.

You need to use MouseEnter and MouseLeave events of the textbox to make changes in your textbox. As far as I remember when mouse enters to your textbox you want to change the border color in MouseEnter event and set it back to its previous state in MouseLeave event.

But textbox class does not have a border color property so you have to create your own custom control and tweak your textbox from there, not from textbox class.
