c# - From database to datetime picker

Question

I have a form with few datetime pickers, to be exact two pairs of dates and times.

Data from those pickers is combined and saved to database as DateTime in format

 16/05/2012 11:28:00 a.m.

Now, what I want to do is get value from database and put it into datetime pickers.

I've tried something like

string plannedDate =(dbFunctions.SQLReadColumn("task", "PlannedDate", TaskID));
        DateTime pDate = new DateTime(plannedDate.Substring(0,9);
        dtpDatePicker.Value=pDate;

where plannedDate contains string data in format as mentioned above, but I can't convert it to DateTime (second line incorrect). Is there an easy way to do it or do I have to cut the string into pieces for year, month etc?

Answer 1

这样做

dtpDatePicker.Value = Convert.ToDateTime(plannedDate.Substring(0, 10)); 

同样的时间

mytimepicker.Value = Convert.ToDateTime(plannedDate.Substring(10, 6));

Answer 2

我个人喜欢DateTime.TryParse 方法，在您可能收到无效字符串作为输入但不希望抛出异常的情况下：

DateTime dateValue;
if (DateTime.TryParse(dateString, out dateValue))
{
    // Conversion succedded
}
else
{
    // Conversion failed
}

Answer 3

尝试

dateTimePicker1.Value = Convert.ToDateTime( gridView1.GetRowCellValue(rowHandle, "CDATE").ToString());
