Comparing two different date formats

If one date control is using a format different than the other date control, how will you compare the dates? Why will this happen? Why will the two dates be using different formats in the same form? well, you can't argue with the client. can you? This was a real scenario that I faced some time ago. So, convert the dates to one format and compare them. For example,
   string shortDate1 = Microsoft.VisualBasic.Strings.FormatDateTime(Convert.ToDateTime(Date1), Microsoft.VisualBasic.DateFormat.ShortDate);
   string shortDate2 = Microsoft.VisualBasic.Strings.FormatDateTime(Convert.ToDateTime(Date2), Microsoft.VisualBasic.DateFormat.ShortDate);
   if (DateTime.Parse(shortDate1) < DateTime.Parse(shortDate2))
   {
         //Display message
   }
In the code above, I am comparing two dates, Date1 and Date2. These dates are stored in string format in the form. So we convert them to date format first and then to short date format and then compare them.
