Screen Class
.NET Framework 2.0
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)
Assembly: System.Windows.Forms (in system.windows.forms.dll)
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.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnGetScreenInfo.Click Dim Index As Integer Dim UpperBound As Integer ' Gets an array of all the screens connected to the system. Dim Screens() As System.Windows.Forms.Screen = _ System.Windows.Forms.Screen.AllScreens UpperBound = Screens.GetUpperBound(0) For Index = 0 To UpperBound ' For each screen, add the screen properties to a list box. ListBox1.Items.Add("Device Name: " + Screens(Index).DeviceName) ListBox1.Items.Add("Bounds: " + Screens(Index).Bounds.ToString()) ListBox1.Items.Add("Type: " + Screens(Index).GetType().ToString()) ListBox1.Items.Add("Working Area: " + Screens(Index).WorkingArea.ToString()) ListBox1.Items.Add("Primary Screen: " + Screens(Index).Primary.ToString()) Next End Sub
private void button1_Click(Object sender, System.EventArgs e)
{
int index;
int upperBound;
// Gets an array of all the screens connected to the system.
Screen screens[] = Screen.get_AllScreens();
upperBound = screens.GetUpperBound(0);
for (index = 0; index <= upperBound; index++) {
// For each screen, add the screen properties to a list box.
listBox1.get_Items().Add("Device Name: " + screens[index].
get_DeviceName());
listBox1.get_Items().Add("Bounds: " + screens[index].get_Bounds()
.ToString());
listBox1.get_Items().Add("Type: " + screens[index].GetType().
ToString());
listBox1.get_Items().Add("Working Area: " + screens[index].
get_WorkingArea().ToString());
listBox1.get_Items().Add("Primary Screen: " +
((System.Boolean)screens[index].get_Primary()).ToString());
}
} //button1_Click
