C # WinForm passing controls as parameters

Recently, to do a WinForm program, you need to pass the form's control as a parameter to another class of functions to use, each time forget, simply write down, for immediate viewing.

1. Set the Modifier property of the control to public

2. Take the space name as a parameter

3. Using System.Windows.Forms in the classes that need to be used;

3. In another class, you can directly declare variable columns of the control type, such as: TextBox, SaveFileDialog, ListView, and other control types

This allows you to move away from the form program, manipulate the control properties of the form in other classes, and facilitate the transfer and control of parameters between forms and forms, and between forms and other classes.
