示例1: FileAge
Public Function FileAge(ByVal fileCreationTime As Long) As System.TimeSpan
Dim now As System.DateTime
now = System.DateTime.Now
Try
Dim fCreationTime As System.DateTime
Dim fAge As System.TimeSpan
fCreationTime = System.DateTime.FromFileTime(fileCreationTime)
fAge = now.Subtract(fCreationTime)
Return fAge
Catch exp As ArgumentOutOfRangeException

Module Example
Public Sub Main()
Dim date1 As New DateTime(2010, 3, 14, 2, 30, 00)
Console.WriteLine("Invalid Time: {0}", TimeZoneInfo.Local.IsInvalidTime(date1))
Dim ft As Long = date1.ToFileTime()
Dim date2 As DateTime = DateTime.FromFileTime(ft)
Console.WriteLine("{0} -> {1}", date1, date2)
End Sub
End Module输出：
