As the others have said, you can use DateTime.TryParseExact, but you also seem to have a European culture format in your date. It might not hurt to make an attempt to use that to perform the conversion:

CultureInfo enGB = new CultureInfo("en-GB"); 
string dateString;
DateTime dateValue;

// Parse date with no style flags.
dateString = "26/01/2011 00:14:00";
DateTime.TryParseExact(dateString, "g", enGB, DateTimeStyles.None, out dateValue);
