System.Globalization Namespace DateTimeFormatInfo Class
Returns the standard patterns in which DateTime values can be formatted.
1. Returns all the standard patterns in which DateTime values can be formatted.
2. Returns all the standard patterns in which DateTime values can be formatted using the specified format character.
The following example uses both versions of GetAllDateTimePatterns to fetch and print the DateTime patterns for the current calendar.
