Convert it to a DateTime, using ParseExact, then output it as whatever format you wish.

C#

string s = "28/09/2012 04:00 PM";
DateTime dt = DateTime.ParseExact(s, "dd/MM/yyyy hh:mm tt", CultureInfo.InvariantCulture);
s = dt.ToString("dd/MM/yyyy HH:mm");

You may need to add

using System.Globalization;

If you put the text cursor in the word "CultureInfo" while it has the red underline, a small blue line will appear at the beginning. Hover the mouse over the blue line, and it will show a drop down which can solve such things for you. (This is generic, not specific to CultureInfo, and a very useful feature of VS)

Hi,

try this code:

DateTime dt = Convert.ToDateTime("28/09/2012 04:00 PM");
MessageBox.Show(dt.ToString("dd/MM/yyyy HH:mm"));

See here for a reference of the available patterns:

Solution 3

You have to use "H" or "HH"

h or hh will give time in 12 hour format
where
H or HH will give time in 24 hr format.

C#

string date=DateTime.Today.ToString("dd/MM/yyyy HH:mm");
