Question

我试图用手法制作一个日历。通过使用纸浆和更多的纸张,我有一个电网,有7栏(日间日)和6行(月终)。如果能够找到每个月第一个月的起始位置,获得一周日和一周(每月)的数目,那么我如何能够找到每周数目(每月0-5个)? 我也只能从那里填补日历上? 我失去了,我不知道还有什么东西要尝试。

public partial class SchedulePage : Page
{        
    MainWindow _parentForm;
    public int dayofweek;

    public SchedulePage(MainWindow parentForm)
    {
        InitializeComponent();
        _parentForm = parentForm;
        // DateTime date = new DateTime(year, month, day);

        _parentForm.bindings = new BindingCamper();          
        _parentForm.bindings.schedule.Add(new Schedule { WeekNo = (int) getWeekNumber(), WeekDay = dayofweek });
        DataContext = _parentForm.bindings;
        // lblTest.Content = dates(2011, 10, 27);
    }

    public double getWeekNumber()
    {
        dayofweek = getWeekDay(2011, 10, 31);
        double h = dayofweek / 7;
        double g = Math.Floor(h);
        return g;
    }

    public int getWeekDay(int year, int month, int day)
    {
        //year = 2011;
        //month = 10;
        //day = 27;
        int[] t = { 0, 3, 2, 5, 0, 3, 5, 1, 4, 6, 2, 4 };
        // year -= month < 3;
        return (year + year / 4 - year / 100 + year / 400 + t[month - 1] + day) % 7;
    }

Answer 1

你们必须使用。日历.GetDayOfWeek和Calendar.Get WeekOf Year ,优于写作。

你们可以保证,如果你写上任何日期/时间处理守则,就会有错,并在不同的地方赢得工作。

public class Row
{
    public string MonthWeek { get; set; }
    public string Year { get; set; }
    public string Month { get; set; }
    public string Day { get; set; }
    public string WeekOfYear { get; set; }
}

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        var l = new List<Row>();
        DateTime startDate = DateTime.Now;
        DateTime d = new DateTime(startDate.Year, startDate.Month, 1);
        var cal = System.Globalization.DateTimeFormatInfo.CurrentInfo.Calendar;
        var ms = cal.GetWeekOfYear(new DateTime(d.Year, d.Month, 1), System.Globalization.CalendarWeekRule.FirstDay, System.DayOfWeek.Sunday);
        for (var i = 1; d.Month == startDate.Month; d = d.AddDays(1))
        {
            var si = new Row();
            var month_week = (d.Day / 7) + 1;
            si.MonthWeek = month_week.ToString();
            si.Month = d.Year.ToString();
            si.Year = d.Month.ToString();
            si.Day = d.Day.ToString();
            si.WeekOfYear = cal.GetWeekOfYear(d, System.Globalization.CalendarWeekRule.FirstDay, DayOfWeek.Sunday).ToString();
            l.Add(si);
        }
        dataGrid1.ItemsSource = l;
    }
}

连同XAML中的强制性数据:

    <DataGrid AutoGenerateColumns="true" Name="dataGrid1" />

页: 1 日历.Get WeekOf Year from Globalization to do this.

http://msdn.microsoft.com/en-us/library/system.globalization.calendar.getweekofyear.aspx” rel=“nofollow” http://msdn.microsoft.com/en-us/library/system.globalization.calendarweekofyear.aspx 。

您应将适当的文化特性从CultureInfo.CurrentCulture转至Get WeekOfYear,以便你能够适当适应当前的文化。

例:

int GetWeekOfYear(DateTime date)
{
    return Calendar.GetWeekOfYear(
        date,
        CultureInfo.CurrentCulture.DateTimeFormat.CalendarWeekRule,
        CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek
    );
}

您可以很容易地将这一条修改成<代码>的延伸方法。日期:

static int GetWeekOfYear(this DateTime date)
{
    return Calendar.GetWeekOfYear(
        date,
        CultureInfo.CurrentCulture.DateTimeFormat.CalendarWeekRule,
        CultureInfo.CurrentCulture.DateTimeFormat.FirstDayOfWeek
    );
}

Answer 3

用@Polynomial回答,我有这个错误:

1. 非法定领域、方法或财产需要标注......

如果你在先把哥里安纳塞的话,那么你就可以把“Get WeekOf岁!”

private static int GetWeekNumber(DateTime time)
{
    GregorianCalendar cal = new GregorianCalendar();
    int week = cal.GetWeekOfYear(time, CalendarWeekRule.FirstFullWeek, DayOfWeek.Monday);
    return week;
}
