How do I get a dattime format in C# that will look like this:

 

2011-09-01 00:00:00:000

I haven't actually tried it (yet), but something like this?

 

String.Format("{0:yyyy/MM/dd HH:mm:ss}", dt);

 

That's assuming we are talking about 1st of September (Americans use have date and month the other way around). The '/' character is depending on your language/regional setting.

 

Edit to add: Found this suggestion String.Format("{0:u}", dt); // "2008-03-09 16:05:07Z" UniversalSortableDateTime
