TryParse special date-format

Question

I try to parse a date-time stamp from an external system as following:

DateTime expiration;
DateTime.TryParse("2011-04-28T14:00:00", out expiration);

Unfortunately it is not recognized. How can I parse this successfully?

Try DateTime.TryParseExact() by specifiying the required format — Nasmi Sabeer, Apr 28 '11 at 10:13

Specify the exact format you want in DateTime.TryParseExact:

DateTime expiration;

string text = "2011-04-28T14:00:00";
bool success = DateTime.TryParseExact(text,
                                      "yyyy-MM-ddTHH:mm:ss",
                                      CultureInfo.InvariantCulture,
                                      DateTimeStyles.None,
                                      out expiration);

I only ever use `TryParseExact`. You can't really trust `TryParse` if the computer may be on (gasp) US settings. – configurator May 01 '11 at 14:41

Try this

DateTime expiration;
DateTime.TryParse("2011-04-28 14:00:00", out expiration);

Without using "T".

Changing the input value (which is supplied elsewhere) isn't nearly as nice a solution as changing how you parse to match the expected format, IMO. – Jon Skeet Apr 28 '11 at 10:16

You need to append "00000Z" to your string argument.

DateTime.TryParse("2011-04-28T14:00:0000000Z", out expiration);

User DateTime.TryParseExact function as following:

DateTime dateValue;

if (DateTime.TryParseExact(dateString, "yyyy-MM-ddTHH:mm:ss", 
                              new CultureInfo("en-US"), 
                              DateTimeStyles.None, 
                              out dateValue))
{
    // Do Something ..
}
