Answer 1

Instead of using Convert.ToDateTime(), try DateTime.ParseExact:

var date1 = DateTime.ParseExact("01/02/2012", "dd/mm/yyyy",
                                CultureInfo.InvariantCulture, DateTimeStyles.None);
var date2 = DateTime.ParseExact("01/02/2012", "mm/dd/yyyy", 
                                CultureInfo.InvariantCulture, DateTimeStyles.None);

A date object always contains both a date component and a time component. When you fetch a DateTime's value via a format you are actually getting a string. The underlying DateTime object - it's value - is not changed at all.

DateTime date1 = new DateTime(2012, 12, 25, 3, 30, 0);
DateTime date2 = new DateTime(2012, 12, 25, 8, 15, 0);

// the dates are the same, the times are different

if (date1.ToShortDateString() == date2.ToShortDateString()) {
   Console.WriteLine ("Date1 equals Date2");        // you should get this
} else {
  Console.WriteLine ("Date1 DOES NOT equal Date2");
}

if (date1 == date2) {
   Console.WriteLine ("Date1 equals Date2");
} else {
  Console.WriteLine ("Date1 DOES NOT equal Date2"); // you should get this
}

if (date1.Date == date2.Date) {
   Console.WriteLine ("Date1 equals Date2");    // you should get this
} else {
  Console.WriteLine ("Date1 DOES NOT equal Date2"); 
}
