vb.net+日期掩码 日期输入掩码

vb.net如何获取时间格式?

可以访问注册表HKEY_CURRENT_USER\Control Panel\International下面的一些键值

如sShortDate键值表示的是短日期sLongDate表示的是长日期

中文下的短日期是 yyyy-M-d

中文下的长日期是 yyyy'年'M'月'd'日'

Q1: VB.NET 正则表达式 日期

var reg = /(.{4}年.{2}月.{2}日|.{2}年.{2}月.{2}日|[^\-]{2}\-[^\-]{2}|[^\/]{2}\/[^\/]{2}|[^\\]{2}\\[^\\]{2})/g;

var str = "sdfasf****年**月**日vb.net+日期掩码，**年**月**日vb.net+日期掩码，**-**vb.net+日期掩码，**/**vb.net+日期掩码，**\**asdfadf";

str.match(reg);
