Question

In my program there are two datetimepickers. I need to get the days in between the chosen dates and store them into a list or array. All these are to be done in the second datetimepicker value changed event

private void dateTimePickertodate_ValueChanged(object sender, EventArgs e)
{
    if (dateTimePickertodate.Value <=dateTimePickerfromdate.Value)
    {
        MessageBox.Show("Choose Correct date");
        textBoxnumofdays.Clear();
    }
    else
    {
        cleave = new LeaveApplication(constr);
        TimeSpan span = dateTimePickertodate.Value - dateTimePickerfromdate.Value;

        if (Mode == 1)
        {                       
            textBoxnumofdays.Text = Convert.ToString(span.Days + 2);
        }
        else
        {
            textBoxnumofdays.Text = Convert.ToString(span.Days + 1);
        }
    }
}

You may try something on these lines

DateTime dtFrom = new DateTime(2011, 02, 5);
DateTime dtTo = new DateTime(2011, 02, 9);
List<DayOfWeek> days = new List<DayOfWeek>();
while (dtTo != dtFrom)
{
   dtFrom = dtFrom.AddDays(1);
   days.Add(dtFrom.DayOfWeek);
}

days would have your week days list (if this is what you intent to have)
