C# Language DateTime.ParseExact(String, String, IFormatProvider)


Example

Converts the specified string representation of a date and time to its DateTime equivalent using the specified format and culture-specific format information. The format of the string representation must match the specified format exactly.

Convert a specific format string to equivalent DateTime

Let's say we have a culture-specific DateTime string 08-07-2016 11:30:12 PM as MM-dd-yyyy hh:mm:ss tt format and we want it to convert to equivalent DateTime object

string str = "08-07-2016 11:30:12 PM";
DateTime date = DateTime.ParseExact(str, "MM-dd-yyyy hh:mm:ss tt", CultureInfo.CurrentCulture);

Convert a date time string to equivalent DateTime object without any specific culture format

Let's say we have a DateTime string in dd-MM-yy hh:mm:ss tt format and we want it to convert to equivalent DateTime object, without any specific culture information

string str = "17-06-16 11:30:12 PM";
DateTime date = DateTime.ParseExact(str, "dd-MM-yy hh:mm:ss tt", CultureInfo.InvariantCulture);

Convert a date time string to equivalent DateTime object without any specific culture format with different format

Let's say we have a Date string , example like '23-12-2016' or '12/23/2016' and we want it to convert to equivalent DateTime object, without any specific culture information

   string date =  '23-12-2016' or date = 12/23/2016';
   string[] formats = new string[] {"dd-MM-yyyy","MM/dd/yyyy"}; // even can add more possible formats.
   DateTime date = DateTime.ParseExact(date,formats, CultureInfo.InvariantCulture,DateTimeStyles.None);

NOTE : System.Globalization needs to be added for CultureInfo Class
