A new DateTime instance with the same date as the current instance, and the time value set to midnight (00:00:00).
The value of the DateTime.Kind property of the returned DateTime value is the same as that of the current instance.
Because the DateTime type represents both dates and times in a single type, it is important to avoid misinterpreting a date returned by the DateTime.Date property as a date and time. For more information, see "Saving and Restoring DateTime Values" in the DateTime topic.
