| // 对Date的扩展,将 Date 转化为指定格式的String | |
| // 月(M)、日(d)、小时(h)、分(m)、秒(s)、季度(q) 可以用 1-2 个占位符, | |
| // 年(y)可以用 1-4 个占位符,毫秒(S)只能用 1 个占位符(是 1-3 位的数字) | |
| // 例子: | |
| // (new Date()).Format("yyyy-MM-dd hh:mm:ss.S") ==> 2006-07-02 08:09:04.423 | |
| // (new Date()).Format("yyyy-M-d h:m:s.S") ==> 2006-7-2 8:9:4.18 | |
