Answer 1

È possibile analizzarlo per DateTime oggetto utilizzando DateTime.ParseExact e poi usare ToString( " Gg/mm/aaaa ") to display the Oggetto DateTime` come.

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"); 

Assicurarsi di includere using System.Globalization; nella parte superiore.

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 ddd dddd}", 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:ddd, MMM d, yyyy}", dt); // "Sun, Mar 9, 2008" 
String.Format("{0:dddd, 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

Prova questo:

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

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

tornerà "2012/02/25 12:00:00"

Answer 4

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"); 

utilizzo questo spazio dei nomi anche: using System.Globalization;
