Converts the value of this instance to all the string representations supported by the standard date and time format specifiers and the specified culture-specific formatting information.
A string array where each element is the representation of the value of this instance formatted with one of the standard date and time format specifiers.
The string array returned by the DateTime.GetDateTimeFormats(IFormatProvider) method is equivalent to combining the string arrays returned by separate calls to the DateTime.GetDateTimeFormats(char, IFormatProvider) method with the "d", "D", "f", "F", "g", "G", "m", "o", "r", "s", "t", "T", "u", "U", and "y" standard format strings. For more information about standard format specifiers, see Standard Date and Time Format Strings.
Each element of the return value is formatted using culture-specific information supplied by provider.
Because this method uses culture-sensitive data, you should not assume that multiple calls to the method will return identical data unless provider is a System.Globalization.CultureInfo object that represents the invariant culture. The data returned by this method can change if the user overrides the individual cultural settings of provider or if an update occurs to the system's cultural data for provider.
