static member SetBufferSize : int * int -> unitstatic member SetBufferSize : int * int -> unitPublic Shared Sub SetBufferSize (width As Integer, height As Integer)参数
- width
- Int32
缓冲区的宽度，以列为单位。
- height
- Int32
缓冲区的高度，以行为单位。
- 属性
例外
height 或 width 小于或等于零。
或
height 或 width 大于或等于 Int16.MaxValue。
或
width 小于 WindowLeft + WindowWidth。
或
height 小于 WindowTop + WindowHeight。
用户没有执行此操作的权限。
出现 I/O 错误。
当前操作系统不是 Windows。
示例
以下示例演示了 WindowLeft、、WindowTop、WindowHeightWindowWidth、BufferWidthBufferHeight、 和 CursorVisible 属性，以及 SetWindowPosition、 SetBufferSize和 ReadKey 方法。 该示例根据屏幕缓冲区宽度在屏幕缓冲区中绘制网格图案。 然后，本示例移动控制台窗口，以响应按下哪个向上键、向下键、向左键或向右键控制台键。 网格模式有助于查看控制台窗口相对于屏幕缓冲区的移动。
