Incorrect date time information displayed when calling Date.toString

[Frinavale]

Want to see something weird?
The following code:

Dim str As New StringBuilder
Dim x As String = "11/6/2009 14:00"
Dim dx As Date
Date.TryParse(x, dx)
str.Append("dx:")
str.Append(Environment.NewLine)
str.Append(dx.Date.ToString)
str.Append(Environment.NewLine)
str.Append(dx.ToString("M/d/yyyy h:mm tt"))
str.Append(Environment.NewLine)
str.Append(dx.Hour.ToString.PadLeft(2, "0"))
str.Append(":")
str.Append(dx.Minute.ToString.PadLeft(2, "0"))
str.Append(":")
str.Append(dx.Second.ToString.PadLeft(2, "0"))
str.Append(Environment.NewLine)
str.Append(Environment.NewLine)
 
MessageBox.Show(str.ToString)
 

Displays:

11/6/2009 12:00 AM
11/6/2009 2:00 PM
14:00:00

What's weird about this is that the Date toString method is incorrect unless provided some sort of format for the time........... ......

That all looks correct to me.
the .Date portion is JUST the date, time information is stripped to "zero" (12:00am), but its STILL a DateTime object.
Oh Frinny, check msdn :-P

Yeah I wasn't checking MSDN I was just fooling around.
The weird part is that if you don't use DateTime and you just use Date it still behaves the same way....

Checking MSDN

Ok that is just silly.

The DateTime class has a "Date" property that returns a new DateTime object with only the date set (but the time is left as default which is midnight).

I know that there is a Date in .NET, I've used it before but it seems that the MSDN only has information on Java's Date class (I was using it yesterday when I was playing around...and for some reason the Date Objects also had Time...hmm I remember something about this from school...but it was a long time ago and I obviously haven't been using Date/DateTime Objects since then so it's all a little fuzzy) .

The weird behaviour of the Date/DateTime Object has been explained now thanks to MSDN.

It's working as expected...

        Dim str As New StringBuilder
        Dim x As String = "11/6/2009 14:00"
        Dim dx As Date
        Date.TryParse(x, dx)
        str.Append("dx:")
        str.Append(Environment.NewLine)
        str.Append(dx.Date.ToString) ' <-- returns a new DateTime Object with just the date set
        str.Append(Environment.NewLine)
        str.Append(dx.ToString) ' <--uses the current DateTime Object 
        str.Append(Environment.NewLine)
        str.Append(dx.ToString("M/d/yyyy h:mm tt"))
        str.Append(Environment.NewLine)
        str.Append(dx.Hour.ToString.PadLeft(2, "0"))
        str.Append(":")
        str.Append(dx.Minute.ToString.PadLeft(2, "0"))
        str.Append(":")
        str.Append(dx.Second.ToString.PadLeft(2, "0"))
        str.Append(Environment.NewLine)
        str.Append(Environment.NewLine)

-Frinny <-- feeling like a newbie all over again

Well "Date" must be a VBNET only object, since it's not part of regular .NET. Don't believe it ever has been either. You're regressing back to VB hehe.

You can do DateTime.Now.To ShortDateString (), if you don't want the time info.
