</StackPanel>

我试图突出显示当前日期 xaml.cs：

public void Initialize_Calendar(DateTime date)
{

    CalendarHeader.Text = date.ToString("MMMM yyyy");
    date = new DateTime(date.Year, date.Month, 1);
    int dayOfWeek = (int)date.DayOfWeek + 1;
    int daysOfMonth = DateTime.DaysInMonth(date.Year, date.Month);
    int i = 1;
    foreach (var o1 in Calendar.Children)
    {
        foreach (var o2 in (o1 as StackPanel).Children)
        {
            var o3 = (o2 as Grid).Children[0] as TextBlock;
            if (i >= dayOfWeek && i < (daysOfMonth + dayOfWeek))
                o3.Text = (i - dayOfWeek + 1).ToString();
            else
                o3.Text = "";
            i++;
            if (calendarDate.Date.Equals(DateTime.Now.Date))
            {
                o3.Foreground = new SolidColorBrush(Colors.Blue);
            }
        }
    }

DateTime calendarDate;
public MainPage()
{
    this.InitializeComponent();

    this.NavigationCacheMode = NavigationCacheMode.Required;

    calendarDate = DateTime.Today;
    Initialize_Calendar(calendarDate);
}
