注解

“F”标准格式字符串是属性的 FullDateTimePattern 别名。 换句话说,分配给此属性的自定义格式字符串定义“F”标准格式字符串的结果字符串的格式。 有关详细信息,请参阅 标准日期和时间格式字符串

通过连接LongDatePattern用空格分隔的属性,LongTimePattern动态生成属性的值FullDateTimePattern。 此动态分配在以下条件下发生:

  • 如果在显式设置属性值之前检索属性值。

  • 当属性的值 LongDatePattern 发生更改时。

  • 当属性的值 LongTimePattern 发生更改时。

如果属性的值 Calendar 发生更改,则此属性将受到影响。
