System.Windows.Controls
组件常用属性：
SelectedDate：获取或设置当前被选中的日期
DisplayDate：获取或设置日期以显示
DisplayDateStart：获取或设置被显示的第一个日期
DisplayDateEnd：获取或设置被显示的最后一个日期
SelectionMode：获取或设置Calendar组件的选取模式
None：设置日历为不可选
SingleDate：只能选择单一日期
SingleRange：只能连续选取日期
MultipleRange：能连续或者间隔地（通过按住Ctrl键）选取日期
BlackoutDates：获取或设置被标记为不可选的一个日期集合
SelectedDates：获取被选中的一个日期集合
IsTodayHighlighted：是否将今日日期高亮显示。
组件常用事件：
DisplayDateChanged：显示日期改变
DisplayModeChanged：显示模式改变
SelectedDatesChanged：被选中日期改变
实例：
说明：在属性方面应当重点掌握该组件的BlackoutDates和SelectedDates属性（可用于数据库的交互），在事件方面应当重点掌握SelectedDatesChanged事件。
效果图：
[原始状态]
[显示日期范围]
[SingleRange]
[MultipleRange和BlackoutDates]
[背景图片和背景视频]
