Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

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.

Example

[Visual Basic, C#, C++] The following 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.

[Visual Basic] 
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


[C#] 

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.AllScreens;
    upperBound = screens.GetUpperBound(0);

    for(index = 0; index <= upperBound; index++)
    {

        // 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());

    }

}

[C++] 
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::AllScreens;
        upperBound = screens->GetUpperBound(0);

        for (index = 0; index <= upperBound; index++) {

            // For each screen, add the screen properties to a list box.

            listBox1->Items->Add(String::Concat(
                S"Device Name: ", screens[index]->DeviceName));
            listBox1->Items->Add(String::Concat(
                S"Bounds: ", __box( screens[index]->Bounds)));
            listBox1->Items->Add(String::Concat(
                S"Type: ", screens->Item[index]->GetType()));
            listBox1->Items->Add(String::Concat(
                S"Working Area: ", __box( screens[index]->WorkingArea)));
            listBox1->Items->Add(String::Concat(
                S"Primary Screen: ", __box( screens[index]->Primary)));
        }

    }
