问题
I'm trying to save a date in database with ASP.NET. The datatype of Date in the database is datetime.
I want to save it as for example (23/02/2014 00:00:00)
That is, I want to save Date, Month and Year, and then have time always be 00:00:00. I also want to have zeros before month and/or day when they are only one number. e.g. 02/06/2014 instead of 2/6/2014.
This is possible when the datatype is varchar but how would I do this when the datatype is datetime?
回答1:
dateTime.ToString("dd/MM/yyyy");
will set the time to zero. MM and dd will add zero if needed
SQL will know the correct date if you add this:
DateTime.Now.ToString("dd/MM/yyyy",System.Globalization.CultureInfo.GetCultureInfo("he-IL"));
update
System.Globalization.CultureInfo info = CultureInfo.CurrentCulture;
Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.CreateSpecificCulture("he-IL");
command.Parameters.AddWithValue("@info",DateTime.Now);
Thread.CurrentThread.CurrentCulture = info;
回答2:
You should store the DataTime on the database without problem using Parameter for sample:
command.Parameters.Add("DateField", SqlDbType.DateTime, datetime);
When you want to show on asp.net page, you should get the DateTime struct and format it , for sample:
label1.Text = dateTime.ToString("MM/dd/yyyy");
To know more about dateTime formats, look this link on MSDN documentation: http://msdn.microsoft.com/en-us/library/8kb3ddd4(v=vs.110).aspx

Just use a date type parameter and the Date property.
command.Parameters.AddWithValue("@info", DateTime.Now.Date);
