Question

我正在用C＃开发学校管理系统。净。我需要通过点击日历中的日期来让用户添加事件，并且添加后日期应该是粗体。我试过下面的代码，但只有最后添加的日期是粗体。但我需要大胆选择每一天。有人可以帮我将所有选定的日期添加到Bolded Days数组吗？我会感激任何帮助。这是我的代码。

//Create method for add bold days
public void boldDays()
        {
            List<DateTime> l = new List<DateTime>();


            l.Add(DateTime.Parse(monthCalendar1.SelectionStart.ToLongDateString()));


            DateTime[] s = l.ToArray();
            monthCalendar1.BoldedDates = new DateTime[] { };
            monthCalendar1.BoldedDates = l.ToArray();
        }






//Executing method when a button click
private void btnRefresh_Click(object sender, EventArgs e)
        {
            boldDays();
        }

Answer 1

从您的代码中，您只添加了一个日期。您需要遍历事件列表。以下代码可能有所帮助：

public void boldDays()
{
    List<DateTime> l = new List<DateTime>();
    foreach (var event in savedEvents)
    {
        l.Add(event.Date);
    }
    monthCalendar1.BoldedDates = l.ToArray();
}

Answer 2

您只是在数组中添加开始日期。试试这个

public void boldDays()
{
    List<DateTime> l = new List<DateTime>();
    for(DateTime m = monthCalendar1.SelectionRange.Start;m <= monthCalendar1.SelectionRange.End; m = m.AddDays(1) )
    {
        l.Add(DateTime.Parse(m.ToLongDateString()));
    }


    //monthCalendar1.BoldedDates = new DateTime[] { };
    l.AddRange(monthCalendar1.BoldedDates); //If you want to preserve previously added dates then add previously added dates to list as  
    monthCalendar1.BoldedDates = l.ToArray();
}

将加固日添加到月份日历
