Bug in System.Globaliz ation.Calendar class?

[greyseal]

Consider the following:

As I post this, it is June 11th, 2004.
My desk calendar tells me it is day 163 of the current year.

This code:

Calendar myCal = CultureInfo.Inv ariantCulture.C alendar;
DateTime theDate = new DateTime(DateTi me.Now.Year, DateTime.Now.Mo nth,
DateTime.Now.Da y, new GregorianCalend ar() );
string dateBack = theDate.ToStrin g("D") + " (" +
myCal.GetDayOfY ear(theDate).To String() + ")";

returns Friday, June 11, 2004 (150)

Obviously, the day of the year is incorrect. What am I doing wrong?

TIA.

greyseal,
Your code converted to VB.NET produces:

dateBack "Friday, June 11, 2004 (163)" String

Under VB.NET 2003 on Windows XP Pro with regional settings for the U.S.

Dim myCal As Calendar = CultureInfo.Inv ariantCulture.C alendar
Dim theDate As DateTime = New DateTime(DateTi me.Now.Year,
DateTime.Now.Mo nth, DateTime.Now.Da y, New GregorianCalend ar)
Dim dateBack As String = theDate.ToStrin g("D") + " (" +
myCal.GetDayOfY ear(theDate).To String() + ")"

Just curious why do you get the InvariantCultur e's Calendar then pass New
GregorianCalend ar to DateTime? I would expect you should use the same
calendar in both cases!

Hope this helps
Jay

Not sure - when I run the code, I get back the correct answer.

Could you post a short but complete program which demonstrates the
problem?

See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.

The InvariantCultur e and Gregorian references slipped in as I tried
different options to make the dang thing work (see
System.Globiliz ation.Calendar) .

I finally got back to the project today and decided to try the
following:

dateBack = theDate.ToStrin g("D") + " (" + theDate.DayOfYe ar + ")";

Worked like a champ - how'd I miss that?

Go figure.
