DateTime format to SQL format using C#

Question

I am trying to save the current date time format from C# and convert it to an SQL Server date format like so yyyy-MM-dd HH:mm:ss so I can use it for my UP

Answer 1

Using the standard datetime format "s" will also ensure internationalization compatibility (MM/dd versus dd/MM):

myDateTime.ToString("s");

=> 2013-12-31T00:00:00
