Examples

The following code example shows how to use various methods and properties of the Screen class. The example calls the AllScreens property to retrieve an array of all the screens connected to the system. For each returned Screen, the example adds the device name, bounds, type, working area, and primary screen to a ListBox. To use the example, add a ListBox and a Button to a form, and then add a Click event handler for the button.

private:
    void button1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
    {
        // For each screen, add the screen properties to a list box.
        for each (Screen^ screen in Screen::AllScreens) {
            listBox1->Items->Add( 
                String::Concat("Device Name: ", screen->DeviceName));
            listBox1->Items->Add( 
                String::Concat("Bounds: ", screen->Bounds));
            listBox1->Items->Add( 
                String::Concat("Type: ", screen->GetType()));
            listBox1->Items->Add( 
                String::Concat("Working Area: ", screen->WorkingArea));
            listBox1->Items->Add( 
                String::Concat("Primary Screen: ", screen->Primary));
        }
    }

private void button1_Click(object sender, System.EventArgs e)
{
    // For each screen, add the screen properties to a list box.
    foreach (var screen in System.Windows.Forms.Screen.AllScreens)
    {
        listBox1.Items.Add("Device Name: " + screen.DeviceName);
        listBox1.Items.Add("Bounds: " + 
            screen.Bounds.ToString());
        listBox1.Items.Add("Type: " + 
            screen.GetType().ToString());
        listBox1.Items.Add("Working Area: " + 
            screen.WorkingArea.ToString());
        listBox1.Items.Add("Primary Screen: " + 
            screen.Primary.ToString());
    }
}

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    ' For each screen, add the screen properties to a list box.
    For Each screen In System.Windows.Forms.Screen.AllScreens
        With ListBox1.Items
            .Add("Device Name: " + screen.DeviceName)
            .Add("Bounds: " + screen.Bounds.ToString())
            .Add("Type: " + screen.GetType().ToString())
            .Add("Working Area: " + screen.WorkingArea.ToString())
            .Add("Primary Screen: " + screen.Primary.ToString())
        End With
    Next
End Sub

Remarks

The constructor for this object is not public, so you cannot explicitly create a Screen object. The object is created when you call its public methods.

Properties

BitsPerPixel	Gets the number of bits of memory, associated with one pixel of data.
Bounds	Gets the bounds of the display.
DeviceName	Gets the device name associated with a display.
Primary	Gets a value indicating whether a particular display is the primary device.
PrimaryScreen	Gets the primary display.
WorkingArea	Gets the working area of the display. The working area is the desktop area of the display, excluding taskbars, docked windows, and docked tool bars.
