Screen Class

Represents a display device or multiple display devices on a single system.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public class Screen

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.

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. 
    foreach (var screen in System.Windows.Forms.Screen.AllScreens)
        listBox1.Items.Add("Device Name: " + screen.DeviceName);
        listBox1.Items.Add("Bounds: " + 
        listBox1.Items.Add("Type: " + 
        listBox1.Items.Add("Working Area: " + 
        listBox1.Items.Add("Primary Screen: " +
