Converting datetime of the format MM/dd/yyyy HH:mm:ss.fff to yyyy-MM-dd HH:mm:ss.fff in asp.net C#

Asked by: amukta

Hi!

I have a drop down list with  a list of dates in the format  MM/dd/yyyy HH:mm:ss.fff . when I select a date from the dropdown list, it needs to be sent to thae database
and retrieve the information. In the table, the date is of the format  yyyy-MM-dd HH:mm:ss.fff

when the send the value as DateTime.Parse(ddl.selected value.ToString()),

it's not converting the date to the appropriate format.

Please let me know, how can I get the desired format.
Thanks a lot in advance!

Is there anyway of converting the date time of the form MM/dd/yyyy HH:mm:ss.fff to yyyy-MM-dd HH:mm:ss.fff   in sql server as well as c#?

Could you please provide me the logic or code.

 

by: Omego2KPosted on 2009-10-25 at 13:01:22ID: 25657986

Datetime currentTime = DateTime.Now;

string currentTimeAsString = currentTime.ToString("yyyy-MM-dd HH:mm:ss.fff");

There is no formatting like that for dates in MS SQL Server. There is a limited one which is this:

If this does not answer your question, please let me know what you would like to do exactly.

You don't store the value of a datetime in SQL server formatted...  It is just an integer offset from some starting date (e.g. Jan. 01, 1970). If you wanted to store it formatted, then you would need to use a varchar/char column for storage.

What is your concern storing the date already formatted? Are you doing some separate reporting outside of your C# application for which you would like to maintain consistency? You can format the data in your C# app before displaying to the user if you are pulling data from the DB in your app.
