What is the difference between two formats you have stated above?

Two-digit hour?

I sure hope that "in your datatable" it is a DateTime and not a string.

yes it is datetime and not a string.

Try this:
string a=DateTime.ParseExact("29/07/2014 6:07:05 AM", "dd/MM/yyyy h:mm:ss tt", CultureInfo.InvariantCulture).ToString("dd/MM/yyyy hh:mm:ss tt");

The exception this was giving to you is because ParseExact expects the format of the string to convert,not the format you want to convert it to. That is done in the ToString method.

1. I could be blind but there is no difference between the date formats you listed in your first sentence.
2. DateTime.ParseExact() expects a string first and you passed in 29/07/2014 6:07:05 PM, which is not a string. You need to put it in quotes for it to be a string, "29/07/2014 6:07:05 PM"

Yes there is difference. I could not see too initially. Check hour in both dates one is having one-digit hour "9/07/2014 6:07:05 PM"
and another is having two-digit "29/07/2014 06:07:05 PM". :)

Wow. Good eyes.

sorry i forgot to put date in double quotes while posting question but the date is written inside double requirement is in whatever format the time comes it should be converted to "hh:mm:ss tt" format.

Did you tried my solution?

OK. You have the code so what is the issue? Your code would work.

DateTime.ParseExact("29/07/2014 6:07:05 PM", "dd/MM/yyyy hh:mm:ss tt", CultureInfo.InvariantCulture).ToString();
