convert datetime to yyyy/MM/dd

How can I convert a datetime object to the format yyyy/MM/dd? I am trying this:

DateTime selectedDate =Convert.ToDateTime( Calendar1.SelectedDate.ToShortDateString());
selectedDate = DateTime.ParseExact(selectedDate, "yyyy/MM/dd", CultureInfo.InvariantCulture);

But I get the following errors:

The best overloaded method match for 'System.DateTime.ParseExact(string, string, System.IFormatProvider)' has some invalid arguments

or

Argument '1': cannot convert from 'System.DateTime' to 'string'

ParseExact converts a string to a datetime, so 

selectedDate = DateTime.ParseExact("2012/02/29", "yyyy/MM/dd", CultureInfo.InvariantCulture);

would work. Not sure why you want to convert a datetime to a datetime??

Use Calendar1.SelectedDate.ToString("yyyy/MM/dd");

Date format makes sense when you are going to convert it to string or display in UI/somewhere else.

If Calendar1.SelectedDate is of DateTime type:

string date = Calendar1.SelectedDate.ToString(
                                      "yyyy/MM/dd", 
                                       CultureInfo.InvariantCulture);

If Calendar1.SelectedDate is of string type:

string date = DateTime.ParseExact(
                          Calendar1.SelectedDate, 
                         "yyyy/MM/dd", 
                          CultureInfo.InvariantCulture);

A DateTime does not have an inherent format - only an internal representation.

Formatting comes into play when you want to display the value of the DateTime instance:

string formatted = DateTime.ToString("yyyy/MM/dd", CultureInfo.InvariantCulture);

The above formatted string will contain the values of the DateTime instance in the required format.
