How to obtain form's inner width and height

问题

As per title.

I am writing a program that all components can adjust size automatically by form's size.

When I using this.Width and this.Height properties, its return value is the width and height of whole form (red frame).

How to get the form's width and height of its inner area (green frame)?

回答1:

Use this.ClientSize.Width and this.ClientSize.Height.

Yes, You can check by this.ClientSize.Width and this.ClientSize.Height. Or you can put Panel in form and Dock fill and get this.panel1.width/ this.panel1.height as well.
