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.

"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".)

string Time = "16:23:01"; DateTime date = DateTime.Parse(Time, System.Globalization.CultureInfo.CurrentCulture); string t = date.ToString("HH:mm:ss tt"); 

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.

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
