示例1:
Dim dateString As String
Dim parsedDate As DateTimeOffset
dateString = "05/01/2008 6:00:00"
' Assume time is local
If DateTimeOffset.TryParse(dateString, Nothing, _
DateTimeStyles.AssumeLocal, _
parsedDate) Then
Console.WriteLine("'{0}' was converted to {1}.", _
dateString, parsedDate.ToString())
Else
Console.WriteLine("Unable to parse '{0}'.", dateString)
End If
' Assume time is UTC
If DateTimeOffset.TryParse(dateString, Nothing, _
DateTimeStyles.AssumeUniversal, _
parsedDate) Then
Console.WriteLine("'{0}' was converted to {1}.", _
dateString, parsedDate.ToString())
Else
Console.WriteLine("Unable to parse '{0}'.", dateString)
End If
' Parse and convert to UTC
dateString = "05/01/2008 6:00:00AM +5:00"
If DateTimeOffset.TryParse(dateString, Nothing, _
DateTimeStyles.AdjustToUniversal, _
parsedDate) Then
Console.WriteLine("'{0}' was converted to {1}.", _
dateString, parsedDate.ToString())
Else
Console.WriteLine("Unable to parse '{0}'.", dateString)
End If输出：
