參數
- left
- Int32
游標的資料行位置。 資料行由左至右,從 0 開始編號。
- top
- Int32
游標的資料列位置。 資料列由上至下,從 0 開始編號。
- 屬性
例外狀況
使用者沒有執行這項動作的權限。
發生 I/O 錯誤。
範例
這個範例會示範 CursorLeft 和 CursorTop 屬性,以及和 SetCursorPosition Clear 方法。 此範例會定位游標,以決定下一次寫入的位置,以使用 "+"、"|" 和 "-" 字串的組合,以5個字元的矩形繪製5個字元。 請注意,您可以使用其他字串的組合,以較少的步驟來繪製矩形。

備註
您 SetCursorPosition 可以使用方法來指定主控台視窗中下一次寫入作業的開始位置。 如果指定的游標位置位於目前顯示在主控台視窗中的區域之外,則視窗來源會自動變更,使游標變成可見。
每次將字元寫入主控台視窗時,資料指標都會自動移至下一個字元位置。 如果游標位於主控台視窗的右下角字元位置,下一次寫入作業會使主控台視窗滾動,讓游標保持可見。 如果您想要將字元寫入到右下角的字元位置,而不會造成主控台視窗滾動,請使用 MoveBufferArea 方法將字元移至該位置。
