Magic strings for converting DateTime to string Using C#

Question

I was greeted with a nasty bug today. The task is pretty trivial, all I needed to do is to convert the DateTime object to string in \"yyyymmdd\" format

Answer 1

String.Format("{0:0000}{1:00}{2:00}", dateTime.Year, dateTime.Month, dateTime.Day);

You could use this instead, I prefer the terse format though. Instead of 00 you can also use MM for specific month formatting (like in DateTime.ToString()).
