- left
- Int32
Die Spaltenposition der linken oberen Ecke des Konsolenfensters.
- top
- Int32
Die Zeilenposition der linken oberen Ecke des Konsolenfensters.
- Attribute
Ausnahmen
left oder top ist kleiner als 0.
- oder -
left + WindowWidth ist größer als BufferWidth.
- oder -
top + WindowHeight ist größer als BufferHeight.

E/A-Fehler
Das aktuelle Betriebssystem ist nicht Windows.
Beispiele
Im folgenden Beispiel werden die WindowLeft Eigenschaften , , , , , und sowie die WindowTop Methoden , und WindowWidth WindowHeight BufferWidth BufferHeight CursorVisible SetWindowPosition SetBufferSize ReadKey veranschaulicht. Das Beispiel zeichnet ein Rastermuster im Bildschirmpuffer basierend auf der Breite des Bildschirmpuffers. Anschließend verschiebt das Beispiel das Konsolenfenster als Reaktion darauf, auf welche der Konsolentasten NACH-OBEN, NACH-UNTEN, NACH-LINKS oder NACH-RECHTS-TASTE gedrückt wird. Das Rastermuster hilft Ihnen, die Verschiebung des Konsolenfensters relativ zum Bildschirmpuffer anzuzeigen.
