推荐答案

使用ParseExact将其转换为DateTime，然后将其输出为所需的任何格式.

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

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");

试试这个代码:

Hi,

try this code:

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

您必须使用"H"或"HH"

h或hh将以12小时格式给出时间
其中
H或HH将以24小时格式给出时间.

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.

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