Completely Maximize C# winform and hiding open window icons at bottom

Question

I already set this.WindowState = FormWindowState.Maximized; and everything looks ok but the Windows open-window icons (such as my browser at the bottom of the page) is still visible.

How to make it invisible?

Answer 1

I just figured out the answer TopMost must be set to true together with FormBorderStyle = FormBorderStyle.None and Bounds = Screen.PrimaryScreen.Bounds.
