範例

以下程式碼範例展示了如何使用該 Screen 類別的各種方法與屬性。 範例中呼叫屬性 AllScreens ，取得所有連接系統螢幕的陣列。 對於每個回傳 Screen的 ，範例會將裝置名稱、界限、類型、工作區域及主螢幕 ListBox加入 。 舉例來說，在表單中加入 a ListBox 和 a Button ，然後為按鈕加上 Click 事件處理器。

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

備註

這個物件的建構子不是公開的，所以你無法明確建立物件 Screen 。 物件是在你呼叫它的公開方法時建立的。
