DateTime removes trailing zeros from milliseconds

Question

My Logger class uses DateTime to print up to millisecond accuracy to logfile, however I notice it keeps removing the training zeros which is rather annoying.

Any ideas

Answer 1

From The FFF Custom Format Specifier;

The "FFF" custom format specifier represents the three most significant digits of the seconds fraction; that is, it represents the milliseconds in a date and time value. However, trailing zeros or three zero digits are not displayed.

You can use lower case fff specifier instead.

Answer 2

.fff. Case matters. I refer you to the excellent documentation here: https://msdn.microsoft.com/library/8kb3ffffd4
