How can you make the form maximize to any computer screen in a Windows Forms application?

Question

So I am making a game on Visual Studio C# and I want the form to be automatically maximized to any user's computer screen when compiled? How can I do that?

the answer depends on what platform you are coding for. WPF? Silverlight? WinForms? etc. — Muad'Dib, Jun 02 '10 at 04:49

You can do it using one of the following --

Set the form WindowState = FormWindowState.Maximized;

Get the screen resolution using following code and set the size of your forms accordingly

int height = Screen.PrimaryScreen.Bounds.Height; 
int width = Screen.PrimaryScreen.Bounds.Width;

WindowState = FormWindowState.Maximized; // not WindowState=Maximized; as for PrimaryScreen work alwyas only if one display or all other display do not have smaller size – gg89 Oct 17 '15 at 18:28
You don't need to set Width and Height if state is Maximized. That does it alone – Fandango68 Sep 12 '22 at 05:46

Set the WindowState property of your form to Maximized.

That will cause your form to be maximumized when it's opened.

In addition, the [FormBorderStyle](http://msdn.microsoft.com/en-us/library/hw8kes41.aspx) can be set to `FormBorderStyle.None` to remove the border as well, for a more *true maximized feeling, no borders added*. – Patrick Jun 02 '10 at 11:14

You can use this.WindowState = FormWindowState.Maximized;

If you are looking for something that will maximize your window on a first click and normalizes your window on a second click, this will help.

private void maximiseButton_Click(object sender, EventArgs e)
    {

        //normalises window
        if (this.WindowState == FormWindowState.Maximized)
        {
            this.WindowState = FormWindowState.Normal;
            this.CenterToScreen();
        }

        //maximises window
        else
        {
            this.WindowState = FormWindowState.Maximized;
            this.CenterToScreen();
        }
    }

On the Form Move Event add this:

    private void Frm_Move (object sender, EventArgs e)
    {
        Top = 0; Left = 0;
        Size = new System.Drawing.Size(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
    }
