如何使用 Pabo 日历设置活动月份的当前日期？

Question

我想在 Pabo 日历中显示当前日期，但只有一个只读属性。

如何设置当前日期？

namespace Pabo.Calendar
{
    [DefaultEvent("MonthChanged")]
    [DefaultProperty("Name")]
    [Designer(typeof(MonthCalendarDesigner))]
    [ToolboxBitmap(typeof(MonthCalendar), "Pabo.Calendar.MonthCalendar.bmp")]
    [ToolboxItem(true)]
    public class MonthCalendar : Control
    {
        public WeekCallBack WeeknumberCallBack;

        public MonthCalendar();

        [Category("Behavior")]
        [Description("")]
        [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
        public ActiveMonth ActiveMonth { get; }
        [Category("Behavior")]
        [DefaultValue(0)]
        [Description("First day of week.")]
        [RefreshProperties(RefreshProperties.All)]
        [TypeConverter(typeof(FirstDayOfWeekConverter))]
        public int FirstDayOfWeek { get; set; }

    }  
}

我对@9​​87654321@ 控件不是很熟悉，但看起来您可以只更新从ActiveMonth 属性返回的对象的Month 或Year 属性。像这样的东西应该可以工作：

// This code example assumes you have an instance of the 
// MonthCalendar object that is called `myMonthCalendar`.
var today = DateTime.Today;
myMonthCalendar.ActiveMonth.Year = today.Year;
myMonthCalendar.ActiveMonth.Month = today.Month;

上面的代码从ActiveMonth 属性中读取值（这是ActiveMonth 类的一个实例，它又包含两个属性Year 和Month）。接下来，它将Year 和Month 属性设置为所需的值。上面代码的更详细版本是：

// This code example assumes you have an instance of the 
// MonthCalendar object that is called `myMonthCalendar`.
var today = DateTime.Today;
var activeMonth = myMonthCalendar.ActiveMonth; // Here we only read the ActiveMonth property.
activeMonth.Year = today.Year; // Here we update or set the Year value
activeMonth.Month = today.Month; // Here we update or set the Month value
