在这个颜值当道，屌丝闪边的时代，拼不过颜值拼内涵，只有知识丰富才能提升一个人的内在气质和修养，所谓人丑就要多学习，今天图老师给大家分享计算两个日期间的工作日，希望可以对大家能有小小的帮助。
【 tulaoshi.com - 编程语言 】
本示例的功能是如何计算给定的两个日期之间的工作日，你可以选择是否将星期六或星期日也包括进去。同时本程序还允许你可入一些假期，从而在计算时将这些假期排除在外。PublicPropertyGetIncludeLastDate()AsBoolean
在默认情况下，BusinessDateDiff函数不包括你输入的最后一天。将该属性值设为真，程序把你输入的最后一天包括在计算中。
方法
PublicSubHolidayAdd(dHolidayAsDate)
添加一个假期列表，以便在计算时排除这些假期。在默认情况下，没有添加任何假期。
PublicSubHolidayRemove(dHolidayAsDate)
从假期列表移除假期
PublicSubHolidayClear()
清除全部假期列表
