Persian Calendar Class simple conversion problem

Microsoft has introduced a Persian Calendar Class in ASP.net 2.0


I have looked at the methods and the only way I have managed to convert
a date from Persian to Gregorian or vice versa is to use the getyear,
getmonth and getdayofmonth methods. ie. my code looks something like

'Get gregorian date and return persian date
Function PDate(ByVal g As Date) As Date
Dim pc As New System.Globaliz ation.PersianCa lendar
Dim persian As Date
Dim year As Integer = pc.GetYear(g)
Dim month As Integer = pc.GetMonth(g)
Dim day As Integer = pc.GetDayOfMont h(g)
persian = day & "/" & month & "/" & year
persian = CType(persian, Date)
Return persian
End Function
However, I run into a problem for Persian dates such as 31/06/1385
(equivalent to 22/09/2006), where 31 days exist in the 6th month of the
Persian month but not in the Gregorian month. The code refuses to
accept this as a valid date format.

So, I am sure I must be using the wrong approach with this class, i.e.
the wrong methodology for conversions between the Persian and Gregorian
calendar. Could somebody possibly have a look at the class and tell me
what I should be doing instead?

Kind regards,
