WinForm Implement Full-screen method

1, the Realization form full screen display

Method: Do the following in a Full-screen method

This. FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

This. WindowState = System.Windows.Forms.FormWindowState.Maximized;

2. Realize the full screen display of a control in the window body

Method: For example, to display the RichTextBox control in full screen, as follows (this is the current form)

This. FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
This. windowstate=formwindowstate.maximized;
Rectangle ret = Screen.getworkingarea (this);

This.richTextBox2.ClientSize = new Size (ret. Width, ret. Height);
This.richTextBox2.Dock = DockStyle.Fill;
This.richTextBox2.BringToFront ();

3, exit full screen, restore original appearance

Method: The prerequisite is to define a class member variable to hold the original size (size) of the control you want to Full-screen, and then initialize it within the constructor to the control's original size

In the exit Full-screen method, the following actions

This. FormBorderStyle = System.Windows.Forms.FormBorderStyle.Sizable;
This. WindowState = Formwindowstate.normal;
This.richTextBox2.ClientSize = Primarysize;//primarysize is the original size of the control
This.richTextBox2.Dock = Dockstyle.none;
