c# - How do I make a WinForms app go Full Screen

Question

I have a WinForms app that I am trying to make full screen (somewhat like what VS does in full screen mode).

Currently I am setting FormBorderStyle to None and WindowState to Maximized which gives me a little more space, but it doesn't cover over the taskbar if it is visible.

What do I need to do to use that space as well?

For bonus points, is there something I can do to make my MenuStrip autohide to give up that space as well?

Answer 1

To the base question, the following will do the trick (hiding the taskbar)

private void Form1_Load(object sender, EventArgs e)
{
    this.TopMost = true;
    this.FormBorderStyle = FormBorderStyle.None;
    this.WindowState = FormWindowState.Maximized;
}

But, interestingly, if you swap those last two lines the Taskbar remains visible. I think the sequence of these actions will be hard to control with the properties window.
