MonthCalendar();public MonthCalendar ();Public Sub New ()示例
下面的代码示例显示一个窗体，其中包含显示 MonthCalendar 一个日历年的控件。 该示例演示如何设置 BackColor、ForeColor、、TitleBackColorTitleForeColorCalendarDimensions、 和 TrailingForeColor 属性以自定义日历控件的外观。 其他属性（如 AnnuallyBoldedDates、 BoldedDates和 MonthlyBoldedDates ）设置为自定义哪些日期为粗体。 该示例还设置 FirstDayOfWeek、 MaxDate、 MinDate和 MaxSelectionCount 属性以更改日历格式。 DateSelected还会处理 和 DateChanged 事件，并在窗体上显示其状态。
