推荐答案

传递的文本框，有几种方法可以做到这一点，包括Form2中的公共属性会更新文本框.
但是，执行此操作的正确方法是在Form1中通知事件数据可用"，该事件在Form2中进行处理并根据需要进行更新.

There are several ways to do this, including public properties in Form2 which updates the textbox.
However, the proper way to do it is to signal an event "Data available" in Form1 which is handled in Form2 and updates as necessary.
