Question

What is the best way to add zeros to date time in C#

Example string “9/10/2011 9:20:45 AM” convert to string “09/10/2011 09:20:45 AM”

Answer 1

If you say, that it is both strings, then you should use the DateTime.TryParse method:

DateTime dt;
if (DateTime.TryParse("9/10/2011 9:20:45 AM", out dt))
{
    Console.WriteLine(dt.ToString("dd/MM/yyyy hh:mm:ss tt"));
}
else
{
    Console.WriteLine("Error while parsing the date");
}
