C＃日期时间为“YYYYMMDDHHMMSS”格式
我想将C＃日期时间转换为“YYYYMMDDHHMMSS”格式。 但我没有找到一种内置的方法来获得这种格式？ 任何意见？
DateTime.Now.ToString("yyyyMMddHHmmss"); // case sensitive
这个网站有很好的例子检查出来
// create date time 2008-03-09 16:05:07.123
DateTime dt = new DateTime(2008, 3, 9, 16, 5, 7, 123);
String.Format("{0:y yy yyy yyyy}", dt); // "8 08 008 2008" year
String.Format("{0:M MM MMM MMMM}", dt); // "3 03 Mar March" month
String.Format("{0:d dd ddd dddd}", dt); // "9 09 Sun Sunday" day
String.Format("{0:h hh H HH}", dt); // "4 04 16 16" hour 12/24
String.Format("{0:m mm}", dt); // "5 05" minute
String.Format("{0:s ss}", dt); // "7 07" second
String.Format("{0:f ff fff ffff}", dt); // "1 12 123 1230" sec.fraction
String.Format("{0:F FF FFF FFFF}", dt); // "1 12 123 123" without zeroes
String.Format("{0:t tt}", dt); // "P PM" A.M. or P.M.
String.Format("{0:z zz zzz}", dt); // "-6 -06 -06:00" time zone
// month/day numbers without/with leading zeroes
String.Format("{0:M/d/yyyy}", dt); // "3/9/2008"
String.Format("{0:MM/dd/yyyy}", dt); // "03/09/2008"
// day/month names
String.Format("{0:ddd, MMM d, yyyy}", dt); // "Sun, Mar 9, 2008"
String.Format("{0:dddd, MMMM d, yyyy}", dt); // "Sunday, March 9, 2008"
// two/four digit year
String.Format("{0:MM/dd/yy}", dt); // "03/09/08"
String.Format("{0:MM/dd/yyyy}", dt); // "03/09/2008"
标准日期时间格式
String.Format("{0:t}", dt); // "4:05 PM" ShortTime
String.Format("{0:d}", dt); // "3/9/2008" ShortDate
String.Format("{0:T}", dt); // "4:05:07 PM" LongTime
String.Format("{0:D}", dt); // "Sunday, March 09, 2008" LongDate
String.Format("{0:f}", dt); // "Sunday, March 09, 2008 4:05 PM" LongDate+ShortTime
String.Format("{0:F}", dt); // "Sunday, March 09, 2008 4:05:07 PM" FullDateTime
String.Format("{0:g}", dt); // "3/9/2008 4:05 PM" ShortDate+ShortTime
String.Format("{0:G}", dt); // "3/9/2008 4:05:07 PM" ShortDate+LongTime
String.Format("{0:m}", dt); // "March 09" MonthDay
String.Format("{0:y}", dt); // "March, 2008" YearMonth
String.Format("{0:r}", dt); // "Sun, 09 Mar 2008 16:05:07 GMT" RFC1123
String.Format("{0:s}", dt); // "2008-03-09T16:05:07" SortableDateTime
String.Format("{0:u}", dt); // "2008-03-09 16:05:07Z" UniversalSortableDateTime
/*

使用c＃6字符串插值格式更新
// create date time 2008-03-09 16:05:07.123
DateTime dt = new DateTime(2008, 3, 9, 16, 5, 7, 123);
$"{dt:y yy yyy yyyy}"; // "8 08 008 2008" year
$"{dt:M MM MMM MMMM}"; // "3 03 Mar March" month
$"{dt:d dd ddd dddd}"; // "9 09 Sun Sunday" day
$"{dt:h hh H HH}"; // "4 04 16 16" hour 12/24
$"{dt:m mm}"; // "5 05" minute
$"{dt:s ss}"; // "7 07" second
$"{dt:f ff fff ffff}"; // "1 12 123 1230" sec.fraction
$"{dt:F FF FFF FFFF}"; // "1 12 123 123" without zeroes
$"{dt:t tt}"; // "P PM" A.M. or P.M.
$"{dt:z zz zzz}"; // "-6 -06 -06:00" time zone
// month/day numbers without/with leading zeroes
$"{dt:M/d/yyyy}"; // "3/9/2008"
$"{dt:MM/dd/yyyy}"; // "03/09/2008"
// day/month names
$"{dt:ddd, MMM d, yyyy}"; // "Sun, Mar 9, 2008"
$"{dt:dddd, MMMM d, yyyy}"; // "Sunday, March 9, 2008"
// two/four digit year
$"{dt:MM/dd/yy}"; // "03/09/08"
$"{dt:MM/dd/yyyy}"; // "03/09/2008"
你已经实际上自己写了这个格式。
yourdate.ToString("yyyyMMddHHmmss")
其他一切都应该是不言自明的。
