Disable some dates in datetimepicker winform c# [duplicate]

Question

I need to disable some dates into DateTimePicker, is it possible? For example, I have a dates range: { 20/12/2014, 21/12/2014, 22/12/2014, 23/12/2014, 24/12/2014 } I need to disable the midle one or in others situations the last one, can anybody help me?

The dateTimePicker1.MainDate and dateTimePicker1.MaxDate is not enough.

Thank you.

Starting from .Net 4 it is possible in WPF. You can then host the WPF datepicker inside a Winforms app. An example (from MSDN) to disable Saturdays and Sundays:

DatePicker datePickerWithBlackoutDates = new DatePicker();

datePickerWithBlackoutDates.DisplayDateStart = new DateTime(2009, 8, 1);
datePickerWithBlackoutDates.DisplayDateEnd = new DateTime(2009, 8, 31);
datePickerWithBlackoutDates.SelectedDate = new DateTime(2009, 8, 10);

datePickerWithBlackoutDates.BlackoutDates.Add(
    new CalendarDateRange(new DateTime(2009, 8, 1), new DateTime(2009, 8, 2)));
datePickerWithBlackoutDates.BlackoutDates.Add(
    new CalendarDateRange(new DateTime(2009, 8, 8), new DateTime(2009, 8, 9)));
datePickerWithBlackoutDates.BlackoutDates.Add(
    new CalendarDateRange(new DateTime(2009, 8, 15), new DateTime(2009, 8, 16)));
datePickerWithBlackoutDates.BlackoutDates.Add(
    new CalendarDateRange(new DateTime(2009, 8, 22), new DateTime(2009, 8, 23)));
datePickerWithBlackoutDates.BlackoutDates.Add(
    new CalendarDateRange(new DateTime(2009, 8, 29), new DateTime(2009, 8, 30)));

datePickerWithBlackoutDates.DateValidationError +=
new EventHandler<DatePickerDateValidationErrorEventArgs>(DatePicker_DateValidationError);

I haven't seen anything similar that would be specifically for Winforms though. As a workaround you can port this WPF component into Winforms app.

Here's MSDN resource on interopeartion of WPF and Winforms:
