[C#] DateTimePicker: MinDate e Range Hour

Question

Hi,

in DateTimePicker I would set MinDate equals to Now, but I would that user can select the range of hours beewten 00 e 23.

I set: 

[code]

datetimeScheduled.MinDate = DateTime.Now;

[/code]

if Now is 22/04/2015 11:39, the user can't select 22/04/2015 09:00

Thanks.
