C# 选取本月周六日方法

用于工作：

1.取本月第一天就是1号

2.取下月第一天再减去一天 就是本月最后一天

3.从月头遍历至月末，判断周几

代码如下：

 #region 提取本月周六日
            DateTime start = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1);
            DateTime end = start.AddMonths(1).AddDays(-1);
            DateTime temp = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1);
            for (int i = start.Day; i <= end.Day; i++)
            {
                if (temp.DayOfWeek == DayOfWeek.Sunday || temp.DayOfWeek == DayOfWeek.Saturday)
                {
                    Console.WriteLine(temp.ToString("yyyy-MM-dd HH:mm:ss"));
                }
                temp = temp.AddDays(1);
            }
            #endregion
