備註

您可以使用 方法,個別或範圍 AddRange 將日期新增至集合。 視屬性的值 SelectionMode 而定,將日期或範圍新增至集合可能會導致清除。 下表列出如何影響 CalendarSelectionModeSelectedDates 屬性。

CalendarSelectionMode 描述
None 不允許選取。 SelectedDate 無法設定,而且無法將任何值新增至 SelectedDates
SingleDate 只有單一日期可以藉由設定 SelectedDate 或 中的 SelectedDates 第一個值來選取。 AddRange 無法使用。
SingleRange 可以選取單一的日期範圍。 設定 SelectedDate 、將日期個別新增至 SelectedDates ,或使用 AddRange 會清除 中的所有先前值 SelectedDates
MultipleRange 可以選取多個不連續的日期範圍。 將日期個別新增至 SelectedDates 或使用 AddRange 將不會清除 SelectedDates 。 設定 SelectedDate 仍然會清除 SelectedDates ,但接著可以新增其他日期或範圍。 新增範圍,其中包含某些已經選取或與另一個範圍重迭的日期會導致範圍聯集,而不會造成例外狀況。
