And if it was successful then the result would be in dttime. TryParse is the better choice than Convert.ToDateTime as it handles exceptions better.

DateTime.ParseExact (yourtime,"dd/MM/yyyy hh:mm:ss tt" ,CultureInfo.InvariantCulture );

change according your need...eg: MM/dd/yy h:mm:ss tt - 05/12/14 4:50:00 AM

TryParse results in a Boolean value that tells if the given string can be set as a date time value.
If that is False the out dttime will not have the desired value.

You might need the CultureInfo whle parsing: See here[^]

You can use a CultureInfo when trying to TryParse. Example:

C#

string dateString;
CultureInfo culture;
DateTimeStyles styles;
DateTime dateResult;

// Parse a date and time with no styles.
dateString = "03/01/2009 10:00 AM";
culture = CultureInfo.CreateSpecificCulture("en-US");  // US format -> Replace with yours!
styles = DateTimeStyles.None;
if (DateTime.TryParse(dateString, culture, styles, out dateResult))
   Console.WriteLine("{0} converted to {1} {2}.", 
                     dateString, dateResult, dateResult.Kind);
else
   Console.WriteLine("Unable to convert {0} to a date and time.", 
                     dateString);

The system isn't recognising the date properly ... try explicitly forcing the date culture ...

CultureInfo culture = CultureInfo.CreateSpecificCulture("en-US");
DateTime dttime;
if (DateTime.TryParse("4/25/2014 6:44:00 AM", culture, DateTimeStyles.None, out dttime))
{
     //use the date;
}

TryParse returns a bool which says if it works - so it's worth checking it.
Try this instead:

C#

bool worked = DateTime.TryParseExact("4/25/2014 6:44:00 AM",
                                     "G", 
                                     new CultureInfo("en-US"),
                                     DateTimeStyles.None,
                                     out dttime);

Why the name change? Bored? M*A*S*H fan?

I'd forgotten about that! It was in response to a comment from Maciej ... he often calls me Hawkeye after I've spotted the one-character typos and things like that. So yes! I think we were bored yesterday, and yes, I'm a closet M*A*S*H fan!
