Answer 1

Use DateTime.Parse() to convert to a true DateTime object and then use the DateTime.ToString() method to output to the format you desire (code example coming):

var dateTime = DateTime.Parse("10/13/2010 8:38:40 AM");
var formattedString = dateTime.ToString("dd/MM/yyyy HH:mm:ss);

Answer 2

Quick and dirty:

DateTime.Parse("10/13/2010 8:38:40 AM", new CultureInfo("en-US")).ToString(new CultureInfo("en-GB"));

Since I know that those formats are for those cultures. However, you can read more about datetime formatting at:

Standard formatting: http://msdn.microsoft.com/en-us/library/az4se3k1.aspx

Custom formatting: http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx

Answer 3

DateTime.ParseExact("10/13/2010 8:38:40 AM","MM/dd/yyyy h:mm:ss tt",CultureInfo.InvariantCulture).ToString("dd/MM/yyyy HH:mm:ss")

edited to make sure 24 hour clock is used in output

Answer 4

        var strfrom = "10/13/2010 8:38:40 AM";
        DateTime dt = DateTime.Parse(strfrom, new CultureInfo("en-US"));
        Console.WriteLine(dt.ToString(new CultureInfo("en-GB")));

Answer 5

var curDate = DateTime.Now.ToString() ;
string customDateFormat = Convert.ToDateTime(curDate).ToString("dd/MM/yyyy");

Answer 6

another variant, one one line:

            DateTime.Parse("10/13/2010 8:38:40 AM", new CultureInfo("en-US")).ToString("dd/MM/yyyy HH:mm:ss");

Answer 7

Or for a more general solution, just pass a format string to DateTime.ToString('formatString'). For example, what you want is DateTime.ToString("dd/MM/yyyy HH:mm:ss"). This allows you to make any format you want.

Example:
DateTime exDT = DateTime.Now;
string exOut = exDT.toString("dd/MM/yyyy HH:mm:ss");

Here's a cheat sheet!

You can use ":" where you want it

f....Full date and time
F....Full date and time (long)
g....Default date and time

s....Sortable date/time
u....Universal time, local timezone
Y....Month / Year dd....Day
