I have a string of the next format "ORDER20100322194007", where 20100322 is a date and 194007 is a time. How to parse a string and get the contained DateTime object?

Date.parse() The Date.parse() method parses a string representation of a date, and returns the number of milliseconds since January 1, 1970, 00:00:00 UTC or NaN if the string is unrecognized or, in some cases, contains illegal date values (e.g. 2015-02-31).
The ToString() method of the DateTime class is used to convert a DateTime date object to string format. The method takes a date format string that specifies the required string representation.
parse() can be used to convert a string into date-time format. The only parameter used is the string.
The Parse method tries to convert the string representation of a date and time value to its DateTime equivalent. It tries to parse the input string completely without throwing a FormatException exception.
Will it always start with ORDER?
string pattern = "'ORDER'yyyyMMddHHmmss"; DateTime dt; if (DateTime.TryParseExact(text, pattern, CultureInfo.InvariantCulture, DateTimeStyles.None, out dt)) { // dt is the parsed value } else { // Invalid string } If the string being invalid should throw an exception, then use DateTime.ParseExact instead of DateTime.TryParseExact
If it doesn't always begin with "ORDER" then do whatever you need to in order to get just the date and time part, and remove "'ORDER'" from the format pattern above.

You can use DateTime.ParseExact method to specify the format that should be used while parsing.
