WeekOfYear in X++ using .net lib - x++

Question

static void Job5(Args _args)
{
int i;
System.DateTime netDttm;
System.Int32 intnet;
;
netDttm = new System.DateTime(2011,03,20 ,13,44,55);
intnet = System.Globalization.CultureInfo.CurrentCulture.Calendar.GetWeekOfYear(netDttm, Globalization.CalendarWeekRule.FirstFourDayWeek, DayOfWeek.Sunday);
i = intnet;
info(int2str(i));
}
I tried the in vb.net it works fine but doing the same in x++(using .net lib) it shows syntax error..All I am trying is to get the week no. from a supplied date. Any insight would be appreciated.
P.S. I found another solution to this which is I created a dll file in VS .net and added this to Reference node(AOT)of AX. It has shorten the code in AX
static void Job5(Args _args)
{
weekofyear.wof asd;
;
asd = new weekofyear.Wof();
print asd.weekofyr(today());
pause;
}

Answer 1

try this
int i;
System.DateTime netDttm;
System.Int32 intnet;
System.Globalization.CultureInfo cultureInfo;
System.Globalization.Calendar calendar;
System.Globalization.CalendarWeekRule calWeekRule
;
netDttm = new System.DateTime(2011,03,20 ,13,44,55);
cultureInfo = System.Globalization.CultureInfo::get_CurrentCulture();
calendar = cultureInfo.get_Calendar();
intnet = calendar.GetWeekOfYear(netDttm, System.Globalization.CalendarWeekRule::FirstFourDayWeek, System.DayOfWeek::Sunday);
i = intnet;
info(int2str(i));

[Note to any future readers: The following described an error in the original code Indranil posted; it does not apply to the code currently in the question, because Indranil fixed this error. The other error was dealt with in another answer from someone else :-).]
You shouldn't be passing a string as the first argument to GetWeekOfYear; it wants a System.DateTime (http://msdn.microsoft.com/en-us/library/system.globalization.calendar.getweekofyear.aspx). (At least, that's true in ordinary .NET; I don't know whether Dynamics AX does some other magical thing. I doubt it does.)
(But if and when you do want a date in the form of a string, those backslashes \ should be forward slashes /.)

Just make sure you load the correct CultureInfo if you expect this code to support word wide locations. Loading the current CultureInfo will load the servers preferred culture. If the user is en-gb and the server is en-us, you first day of week will be incorrect.
To load a specific cultureinfo you can simply do this:
System.Globalization.CultureInfo arCul = new System.Globalization.CultureInfo("en-US");
In the example chosen as answer, the code loads cultureinfo, but the cultureinfo is not used as parameter to the GetWeekOfYear method, which doesnt really make any sense. Instead you could send in the settings from the cultureinfo.
