Question

即使dow和dy中的值相等，它也不会进入循环内部以检查相等性

foreach (DayOfWeek dow in daysofweek)
{
    foreach (day dy in cleave.WeekDays)
    {
        if (Mode == 1)
        {
            //textBoxnumofdays.Text = Convert.ToString(span.Days+2);
            if (dow.Equals(dy))
            {
                textBoxnumofdays.Text = Convert.ToString(span.Days - 1);
            }
            else
            {
                textBoxnumofdays.Text = Convert.ToString(span.Days + 2);
            }
        }
        else
        {
            //textBoxnumofdays.Text = Convert.ToString(span.Days + 1);
            if (dow.Equals(dy))
            {
                textBoxnumofdays.Text = Convert.ToString(span.Days - 1);
            }
            else
            {
                textBoxnumofdays.Text = Convert.ToString(span.TotalDays + 1);
            }
        }
    }
}

public void Getdays()
{
    DateTime dtFrom = new DateTime(dateTimePickerfromdate.Value.Year,
        dateTimePickerfromdate.Value.Month, dateTimePickerfromdate.Value.Day);
    DateTime dtTo = new DateTime(dateTimePickertodate.Value.Year,
        dateTimePickertodate.Value.Month, dateTimePickertodate.Value.Day);
    daysofweek = new List<DayOfWeek>();           
    cleave = new LeaveApplication(constr);         
    while (dtTo != dtFrom)
    {
        dtFrom = dtFrom.AddDays(1);
        daysofweek.Add(dtFrom.DayOfWeek); 
    }
}

Answer 1

我认为你试图检查它是否是工作日

foreach (DayOfWeek dow in daysofweek)
{
}

因此，只需将其与dow == DayOfWeek.Sunday进行比较，然后根据您的要求接受或忽略。

Answer 2

因为对于每个daysofweek，它会执行cleave.WeekDays的完整周期，因此它可能首先激活if部分，然后在下一个周期激活else部分。你想做什么？
