DateTime.ParseE xact(..)

[Pablo]

Hello,

I have big problem with method ParseExact from class DateTime.
Here is code sample:

'-----------------------------------------------------------------------------------------------------------------------------------------
Module Module1
Sub Main()
Console.WriteLi ne("Start...")
Try
Dim dt_ok As DateTime = New DateTime(1899, 12, 29, 0, 0, 0)
Dim dt_exception As DateTime = New DateTime(1899, 12, 30,
0, 0, 1)

Dim str_ok As String = dt_ok.ParseExac t(dt_ok,
"yyyy-MM-dd", System.Globaliz ation.CultureIn fo.InvariantCul ture)
Console.WriteLi ne("OK: " + str_ok)

Dim str_exception As String =
dt_exception.Pa rseExact(dt_exc eption, "yyyy-MM-dd",
System.Globaliz ation.CultureIn fo.InvariantCul ture)
Console.WriteLi ne("OK: " + str_exception)

Catch ex As Exception
Console.WriteLi ne(ex.Message)
End Try
Console.WriteLi ne("Press ENTER for exit...")
Console.ReadLin e()
End Sub
End Module
'-----------------------------------------------------------------------------------------------------------------------------------------

For date 1899/12/29(or 31) ParseExact works fine but for date
1899/12/30 i have exception:
String was not recognized as a valid DateTime. (thrown by ParseExact )

I have read about structure DateTime and i know that this time is
special but i don't understand why it dosn't want to work :/

Tkank you for all aswears.

Pablo,

The datetime.parsee xact converts a string to a datetime
http://msdn.microsoft.com/library/de...xacttopic2.asp

You try to convert a datetime to a string
For that is the overloaded DateTime.ToStri ng very good.

http://msdn.microsoft.com/library/de...ingTopic21.asp

It is very strange that it works with that other date.

I hope this helps,

Cor
