Beispiel
Im folgenden Codebeispiel wird die Verwendung eines der DateTime-Konstruktoren veranschaulicht.
' This example demonstrates the DateTime(Int64) constructor.
Imports System
Imports System.Globalization
Imports Microsoft.VisualBasic
Class Sample
Public Shared Sub Main()
' Instead of using the implicit, default "G" date and time format string, we
' use a custom format string that aligns the results and inserts leading zeroes.
Dim format As String = "{0}) The {1} date and time is {2:MM/dd/yyyy hh:mm:ss tt}"
' Create a DateTime for the maximum date and time using ticks.
Dim dt1 As New DateTime(DateTime.MaxValue.Ticks)
' Create a DateTime for the minimum date and time using ticks.
Dim dt2 As New DateTime(DateTime.MinValue.Ticks)
' Create a custom DateTime for 7/28/1979 at 10:35:05 PM using a
' calendar based on the "en-US" culture, and ticks.
Dim ticks As Long = New DateTime(1979, 7, 28, 22, 35, 5, _
New CultureInfo("en-US", False).Calendar).Ticks
Dim dt3 As New DateTime(ticks)
Console.WriteLine(format, 1, "maximum", dt1)
Console.WriteLine(format, 2, "minimum", dt2)
Console.WriteLine(format, 3, "custom ", dt3)
Console.WriteLine(vbCrLf & "The custom date and time is created from {0:N0} ticks.", ticks)
End Sub 'Main
End Class 'Sample
'
'This example produces the following results:
'
'1) The maximum date and time is 12/31/9999 11:59:59 PM
'2) The minimum date and time is 01/01/0001 12:00:00 AM
'3) The custom date and time is 07/28/1979 10:35:05 PM
'
'The custom date and time is created from 624,376,461,050,000,000 ticks.
