Answer 1

Try this:

string d ="25/02/2012";  
DateTime dtReturn = DateTime.MinValue;

DateTime.TryParseExact(d , "dd/MM/yyyy", dateFormat,
DateTimeStyles.AllowWhiteSpaces, out dtReturn)

will Return "2/25/2012 12:00:00 AM"

DateTime dt = new DateTime(2008, 3, 9, 16, 5, 7, 123);
String.Format("{0:y yy yyy yyyy}", dt);  // "8 08 008 2008"   year
String.Format("{0:M MM MMM MMMM}", dt);  // "3 03 Mar March"  month
String.Format("{0:d dd ffffd ffffdd}", dt);  // "9 09 Sun Sunday" day
String.Format("{0:h hh H HH}",     dt);  // "4 04 16 16"      hour 12/24
String.Format("{0:m mm}",          dt);  // "5 05"            minute
String.Format("{0:s ss}",          dt);  // "7 07"            second
String.Format("{0:f ff fff ffff}", dt);  // "1 12 123 1230"   sec.fraction
String.Format("{0:F FF FFF FFFF}", dt);  // "1 12 123 123"    without zeroes
String.Format("{0:t tt}",          dt);  // "P PM"            A.M. or P.M.
String.Format("{0:z zz zzz}",      dt);  // "-6 -06 -06:00"   time zone
String.Format("{0:M/d/yyyy}", dt);            // "3/9/2008"
String.Format("{0:MM/dd/yyyy}", dt);          // "03/09/2008"
String.Format("{0:ffffd, MMM d, yyyy}", dt);    // "Sun, Mar 9, 2008"
String.Format("{0:ffffdd, MMMM d, yyyy}", dt);  // "Sunday, March 9, 2008"
String.Format("{0:MM/dd/yy}", dt);            // "03/09/08"
String.Format("{0:MM/dd/yyyy}", dt);          // "03/09/2008"

Answer 3

DateTime dt = DateTime.ParseExact(your string date, "d/M/yyyy",
                                  CultureInfo.InvariantCulture);
// for both "1/1/2000" or "25/1/2000" formats
string ndt = dt.ToString("MM/dd/yyyy");

use this namespace also: using System.Globalization;

Answer 4

You can parse it to DateTime object using DateTime.ParseExact and later use ToString("MM/dd/yyyy")to display theDateTime` object like.

string d ="25/02/2012";
DateTime dt = DateTime.ParseExact(d, "d/M/yyyy", CultureInfo.InvariantCulture);
// for both "1/1/2000" or "25/1/2000" formats
string newString = dt.ToString("MM/dd/yyyy");

Make sure to include using System.Globalization; at the top.
