備註

屬性 UniversalSortableDateTimePattern 會定義日期字串的格式,這些字串是由 呼叫 DateTime.ToStringDateTimeOffset.ToString 方法所傳回,以及提供 「u」 標準格式字串的複合格式字串所傳回。 其可用來以可排序次序顯示日期和時間,並在結尾使用通用時間指示項 「Z」。 格式是可排序的,因為它使用年份、月、日、小時、分鐘和秒的前置零。 不論文化特性或格式提供者為何,自訂格式字串 (「yyyy'-'MM'-'dd HH':'mm':'ss'Z'」) 相同。

屬性所 UniversalSortableDateTimePattern 傳回的格式字串會反映已定義的標準,而且屬性是唯讀的。 因此,不論文化特性為何,它一律相同。 自訂格式字串為 "yyyy'-'MM'-'dd HH':'mm':'ss'Z'"。
