Dates themselves don't have formats inherently. You can parse a string into a DateTime
by parsing it with dd/MM/yyyy
format and then convert that into a string using yyyyMMdd
format:
DateTime date = DateTime.ParseExact(text, "dd/MM/yyyy",
CultureInfo.InvariantCulture);
string reformatted = date.ToString("yyyyMMdd", CultureInfo.InvariantCulture);
Or in VB:
Dim date as DateTime = DateTime.ParseExact(text, "dd/MM/yyyy", CultureInfo.InvariantCulture)
Dim reformatted as String = date.ToString("yyyyMMdd", CultureInfo.InvariantCulture)
(And make sure you have an import for System.Globalization
.)
However, ideally you should keep it as a DateTime
(or similar) for as long as possible.

Use the DateTime.ParseExact
method to parse the date, then use DateTimeObj.ToString("yyyyMMdd")
.

Public Function DateFormateYYYYMMDD(ByVal Dtp As DateTimePicker) As String
Try
Dim StrDate, StrYear, StrMonth, StrDay As String
StrDate = FormatDateTime(Dtp.Value, DateFormat.ShortDate)
StrMonth = Month(Dtp.Value)
StrDay = Convert.ToString(Dtp.Value.Day)
StrYear = Year(Dtp.Value)
StrDate = StrYear + "-" + StrMonth + "-" + StrDay
Return StrDate
Catch ex As Exception
End Try
End Function
此函数可用于将日期时间选择器值格式转换为 yyyyMMdd
