سلام دوست عزیز،

اینکار با استفاده از توابع زیر امکان پذیر است:

System.DateTime.ParseExact
System.DateTime.Parse
System.DateTime.TryParse
System.DateTime.TryParseExact
مثالی از MSDN:


Imports System
Imports System.Globalization
Class Class1
Public Shared Sub Main()
' Assume the current culture is en-US.
' The date is February 16, 1992, 12 hours, 15 minutes and 12 seconds.
Dim myDateTimeValue As String = "2/16/1992 12:15:12"
Dim myDateTime As DateTime = DateTime.Parse(myDateTimeValue)
Console.WriteLine("1) myDateTime = {0}", myDateTime)
' Reverse month and day to conform to a different culture.
' The date is February 16, 1992, 12 hours, 15 minutes and 12 seconds.
Dim culture As CultureInfo = New CultureInfo("fr-FR", True)
Dim myDateTimeFrenchValue As String = " 16/02/1992 12:15:12"
Dim myDateTimeFrench As DateTime = _
DateTime.Parse(myDateTimeFrenchValue, _
culture, _
DateTimeStyles.NoCurrentDateDefault)
Console.WriteLine("2) myDateTimeFrench = {0}", myDateTimeFrench)
' The date is February 16, 1992, 12 hours, 15 minutes and 12 seconds.
Dim expectedFormats As String() = {"G", "g", "f", "F"}
myDateTimeFrench = DateTime.ParseExact(myDateTimeFrenchValue, _
expectedFormats, _
culture, _
DateTimeStyles.AllowWhiteSpaces)
Console.WriteLine("3) myDateTimeFrench = {0}", myDateTimeFrench)
End Sub 'Main
End Class 'Class1
'
'This example yields the following results:
'
'1) myDateTime = 2/16/1992 12:15:12 PM
'2) myDateTimeFrench = 2/16/1992 12:15:12 PM
'3) myDateTimeFrench = 2/16/1992 12:15:12 PM
'
