What you ask is not doable in the terms you seek. If you want operations only on the Date parts you should first extract Date parts like this:
var dateString = "8/3/2016 12:00:00 AM";
DateTime date = DateTime.Parse(dateString);
You can work only with the date part using Day, Month, Year properties and if needed DayOfYear, DayOfWeek properties. If you want to print Date only use:
1. Console.WriteLine(date.ToShortDateString()) or
2. Console.WriteLine(date.ToLongDateString()) or
3. Console.WriteLine(date.ToString("d")) // same as ToShortDateString() // or
4. Console.WriteLine(date.ToString("D")) // same as ToLongDateString() // or
5. Console.WriteLine(date.ToString("yyyy/MM/dd")) or
6. Console.WriteLine(date.ToString("//Other custom formats")
