Convert string to Time

I have a time that is 16:23:01. I tried using DateTime.ParseExact, but it’s not working.

Here is my code:

string Time = "16:23:01"; 
DateTime date = DateTime.ParseExact(Time, "hh:mm:ss tt", System.Globalization.CultureInfo.CurrentCulture);

lblClock.Text = date.ToString();

I want it to show in the label as 04:23:01 PM.

Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.

Method 1

“16:23:01” doesn’t match the pattern of “hh:mm:ss tt” – it doesn’t have an am/pm designator, and 16 clearly isn’t in a 12-hour clock. You’re specifying that format in the parsing part, so you need to match the format of the existing data. You want:

DateTime dateTime = DateTime.ParseExact(time, "HH:mm:ss",
                                        CultureInfo.InvariantCulture);

(Note the invariant culture, not the current culture – assuming your input genuinely always uses colons.)

If you want to format it to hh:mm:ss tt, then you need to put that part in the ToString call:

lblClock.Text = date.ToString("hh:mm:ss tt", CultureInfo.CurrentCulture);

Or better yet (IMO) use “whatever the long time pattern is for the culture”:

lblClock.Text = date.ToString("T", CultureInfo.CurrentCulture);

Also note that hh is unusual; typically you don’t want to 0-left-pad the number for numbers less than 10.

(Also consider using my Noda Time API, which has a LocalTime type – a more appropriate match for just a “time of day”.)

Method 2

string Time = "16:23:01";
DateTime date = DateTime.Parse(Time, System.Globalization.CultureInfo.CurrentCulture);

string t = date.ToString("HH:mm:ss tt");

Method 3

This gives you the needed results:

string time = "16:23:01";
var result = Convert.ToDateTime(time);
string test = result.ToString("hh:mm:ss tt", CultureInfo.CurrentCulture);
//This gives you "04:23:01 PM"  string

You could also use CultureInfo.CreateSpecificCulture("en-US") as not all cultures will display AM/PM.

Method 4

The accepted solution doesn’t cover edge cases.
I found the way to do this with 4KB script. Handle your input and convert a data.

Examples:

00:00:00 -> 00:00:00
12:01 -> 12:01:00
12 -> 12:00:00
25 -> 00:00:00
12:60:60 -> 12:00:00
1dg46 -> 14:06

You got the idea…
