C#: How to convert string to Julian date accordingly to the giver format?

Question

my question is how to convert input DateTime value into Julian date format but the result should be in the format "0YYDDD"? I suppose January, 2nd 2011 should look like "011002".

Thanks

Just to note, what you are talking about - that is, the day-of-year - is the Julian *date*. The Julian *calendar* is something else: it's an 'earlier version' of the Gregorian calendar generally used now, with the difference that it didn't have the century/four-century leap year rules http://en.wikipedia.org/wiki/Julian_calendar — AakashM, Dec 09 '10 at 21:38

DateTime dt = new DateTime(2011, 1, 2);
Console.WriteLine( String.Format("{0:0yy0dd}",dt) );

A good cheatsheet can be found here.

Oh wait, maybe you wanted the total number of days since the beginning of the year? January was not a good example month. – riwalk Dec 08 '10 at 23:30
Yes, I want the total number of days. If I have 12 December, it should be "010355". – mimic Dec 08 '10 at 23:45
what is the `0:...` used for? – RobertPitt Dec 09 '10 at 21:47
I don't know. it doesn't matter. Just requirement from bank. – mimic Dec 10 '10 at 01:28

@RobertPitt, the 0: refers to the first parameter of the Format function (after the string, of course). – riwalk Dec 10 '10 at 15:46

Alternatively:

julianFormatString = "0" + (dateTimeVar.Year % 100).ToString() + "0" + dateTimeVar.Day.ToString();
