我希望能够快速参考各种DateTime格式的显示方式,而不是开始编辑,编译,gawk和recurse的繁重过程,直到满意为止.

解决方法:

这显示了当前文化的所有格式：

StringBuilder sb = new StringBuilder();
foreach (string dateTimePattern in DateTimeFormatInfo.CurrentInfo.GetAllDateTimePatterns()) {
    sb.AppendFormat("{0} = {1}\r\n", dateTimePattern, DateTime.Now.ToString(dateTimePattern));
}

StringBuilder内容之后：

M/d/yyyy = 7/18/2012
M/d/yy = 7/18/12
MM/dd/yy = 07/18/12
MM/dd/yyyy = 07/18/2012
yy/MM/dd = 12/07/18
yyyy-MM-dd = 2012-07-18
dd-MMM-yy = 18-Jul-12
dddd, MMMM dd, yyyy = Wednesday, July 18, 2012
MMMM dd, yyyy = July 18, 2012
dddd, dd MMMM, yyyy = Wednesday, 18 July, 2012
dd MMMM, yyyy = 18 July, 2012
dddd, MMMM dd, yyyy h:mm tt = Wednesday, July 18, 2012 4:25 PM
dddd, MMMM dd, yyyy hh:mm tt = Wednesday, July 18, 2012 04:25 PM

我不确定为什么会重复几种模式.
