[System.Runtime.Versioning.SupportedOSPlatform("windows")]
public static void SetBufferSize (int width, int height);
public static void SetBufferSize (int width, int height);
[<System.Runtime.Versioning.SupportedOSPlatform("windows")>]
static member SetBufferSize : int * int -> unit

Public Shared Sub SetBufferSize (width As Integer, height As Integer)
Parameter
- width
- Int32
Die Breite des Pufferbereichs in Spalten.
- height
- Int32
Die Höhe des Pufferbereichs in Zeilen.
- Attribute
Ausnahmen
height
oder width
ist kleiner oder gleich 0 (null).
- oder -
height
oder width
ist größer oder gleich Int16.MaxValue.
- oder -
width
ist kleiner als WindowLeft + WindowWidth
- oder -
height
ist kleiner als WindowTop + WindowHeight

E/A-Fehler
Das aktuelle Betriebssystem ist nicht Windows.
Beispiele
Im folgenden Beispiel werden die WindowLeftEigenschaften , WindowTop, WindowWidth, BufferWidthWindowHeight, BufferHeightund CursorVisible sowie die SetWindowPositionMethoden , SetBufferSizeund ReadKey veranschaulicht. Das Beispiel zeichnet ein Rastermuster im Bildschirmpuffer basierend auf der Bildschirmpufferbreite. Anschließend verschiebt das Konsolenfenster als Reaktion darauf, welche der Konsolentasten NACH-OBEN, NACH-UNTEN, NACH-LINKS oder NACH-RECHTS-TASTE gedrückt wird. Das Rastermuster hilft Ihnen, die Bewegung des Konsolenfensters relativ zum Bildschirmpuffer anzuzeigen.
