客户希望实现计算工作日，除去公休日、节假日，并且规定的公休日上班要算作工作日。
如：2014-06-25 是礼拜三加上3天，是2014-06-28礼拜六。那么得到的时间应该是2014-06-30。
1、后台调用：
1 int days = 3;//累计加的天数 2 DateTime add_date = DateTime.Now; 3 EndDate enddate = new EndDate(); 4 count_date = enddate.Get_Days(add_date, days, 0);
Code
2、实现方法：
1 /// <summary>
2 /// 计算当天是否为公休公休
3 /// </summary>
4 /// <param name="time"></param>
5 /// <returns></returns>
6 public static int GetPublicHoliday(DateTime time)

3、数据库表结构：
注：以上只是实现了基本功能，并且效率不高，因水平有限，希望能有更好的方法。
当前时间+工作日 得到截止日期
