To get time along with Date from DateTimePicker

Question

我有一个格式很短的datetimepicker。我必须在后面的代码中获取时间和日期。现在12：00：0am插入日期和日期。相反，我需要插入当前时间以及从datetimepicker中选择的日期。任何人都可以救命？

Answer 1

Create a new DateTime using the date from your input and the time from DateTime.Now .

DateTime GetDateAndCurrentTime(DateTime date)
{
    return new DateTime(date.Year, date.Month, date.Day, DateTime.Now.Hour, DateTime.Now.Minute, DateTime.Now.Second);
}

Answer 2

The actual DateTime.Value from the picker is a full DateTime object with the current time.

private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
    {
        DateTime dt = dateTimePicker1.Value;
        // or
        string s = string.Concat(dt.ToShortDateString(), DateTime.Now.ToShortTimeString());
    }

Answer 3

Full DateTime:

dateTimePicker1.Value;

'08/21/2011 14:42:11'

Short DateTime:

dateTimePicker1.Value.Date;

'08/21/2011 00:00:00'

The minimum value

'08/21/2011 00:00:00'

The maximum value

'08/21/2011 23:59:59'

Usage:

   var firstDate = dtpFrom.Value.Date; //  0:00:00
   var secondDate =  dtpTo.Value.Date.AddSeconds(86400 - 1); //23:59:59 - 86400 is 24 hours
   var list = Services.GetListForFilter(firstDate, secondDate);
