Standard DateTime Formatting In DateTimeFormatInfo there are defined standard patterns for the current culture. For example property ShortTimePattern is string that contains value h:mm tt for en-US culture and value HH:mm for de-DE culture. Following table shows patterns defined in DateTimeFormatInfo and their values for en-US culture. First column contains format specifiers… Read More »
