DateTimePicker.Valuewants a DateTimenot a string. So you need to parse it:
DateTimePicker.Value想要一个DateTime不是字符串。所以你需要解析它：
Dim dt As DateTime = DateTime.ParseExact("20140118", "yyyyMMdd", CultureInfo.InvariantCulture)
dateTimePicker1.Value = dt
However, just for the sake of completeness, if you need a string 01/18/2014from the DateTimeyou can use DateTime.ToString:
但是，为了完整起见，如果您需要一个字符串01/18/2014，DateTime您可以使用DateTime.ToString：
Dim date As String = dt.ToString("MM/dd/yyyy", CultureInfo.InvariantCulture)
If that is your local date format you could also use these more concise approaches:
如果这是您的本地日期格式，您还可以使用这些更简洁的方法：
)
Dim date As String = dt.ToShortDateString())
Dim date As String = dt.ToString("d")
)
Dim date As String = dt.ToShortDateString())
Dim date As String = dt.ToString("d")
