static member SetBufferSize : int * int -> unitstatic member SetBufferSize : int * int -> unitPublic Shared Sub SetBufferSize (width As Integer, height As Integer)參數
- width
- Int32
以資料行數測量的緩衝區寬度。
- height
- Int32
以列數測量的緩衝區的高度。
- 屬性
例外狀況
height 或 width 小於或等於零。
-或-
height 或 width 大於或等於 Int16.MaxValue。
-或-
width 小於 WindowLeft + WindowWidth。
-或-
height 小於 WindowTop + WindowHeight。
使用者沒有執行這項動作的權限。

範例
下列範例示範 WindowLeft 、 WindowTop 、 WindowHeightWindowWidth 、 BufferWidth 、、 BufferHeight 和 CursorVisible 屬性，以及 、 SetBufferSize 和 SetWindowPositionReadKey 方法。 此範例會根據螢幕緩衝區寬度，在螢幕緩衝區中繪製格線圖樣。 然後，此範例會移動主控台視窗，以回應按下哪個向上鍵、向下鍵、向左鍵或向右鍵。 格線模式可協助您查看相對於螢幕緩衝區的主控台視窗移動。
