This enumeration provides several formatting options for the DateTime.Parse( ) and DateTime.ParseExact( ) methods to use. The values supplied mostly determine how whitespace is dealt with when a string is parsed into a DateTime value by ParseExact( ). When the string is compared to a format pattern, some whitespace can be disregarded if it is not exactly aligned with the pattern. Parse( ) ignores whitespace by default, so AdjustToUniversal and NoCurrentDateDefault are the only relevant values for that method. If the string to parse does not include a date with NoCurrentDateDefault, its result is created with day, month, and year values all set to 1. The date and time are converted to coordinated universal time (UTC) with AdjustToUniversal.

public enum DateTimeStyles {
   None = 0x00000000,
   AllowLeadingWhite = 0x00000001,
   AllowTrailingWhite = 0x00000002,
   AllowInnerWhite = 0x00000004,
   AllowWhiteSpaces = 0x00000007,
   NoCurrentDateDefault = 0x00000008,
   AdjustToUniversal = 0x00000010
}
