C # pass the control as a parameter in winform

Recently I made a winform program design. I need to pass the form control as a parameter to another class function for use. Every time I forget it, I will simply write it down for Instant viewing.

1. Set the modifier attribute of the control to public.

2. Use the space name as the parameter

3. Using system. Windows. forms;

3. In another class, you can directly declare control-type variable columns such as Textbox, savefiledialog, and listview.

In this way, you can remove the form program and operate the control properties of the form in other classes. It also facilitates parameter transfer and mutual control between the form and the form, form and other classes.
