推荐答案

当您单击按钮时，它是获得焦点的按钮，不是文本框。如果要在按钮单击之前检查最后一个聚焦控件，请检查以下内容： c＃ - 找出最后一个焦点的控件 - Stack Overflow [ ^ ]

When you click on the button, it is the button that got the focus, not the textbox. If you want to check the last focused control prior to the button click, check this out: c# - Find out the control with last focus - Stack Overflow[^]
