如何根据当前日期推算出本周的具体日期范围?

[abz98980]

比如当前日期是 2013-10-31,那么本周的具体日期范围就是 2013-10-27至2013-11-02(从上周日至本周六)
关键是有没有相关的方法能得出这样的结果?

DateTime.Now.AddDays(-((int)dt.DayOfWeek + 1))==第一天的日期

有点错误,应该是 DateTime.Now.AddDays(-((int)DateTime.Now.DayOfWeek))

int weekNow = Convert.ToInt32(System.DateTime.Now.DayOfWeek);//星期天 int daydiff = (-1) * weekNow + 1; int dayadd = 7 - weekNow; timeStart = System.DateTime.Now.AddDays(daydiff).ToString("yyyy-MM-dd");//本周第一天（星期一） timeEnd = System.DateTime.Now.AddDays(dayadd).ToString("yyyy-MM-dd");//本周最后一天（周日） 如果是周日----》星期六的话 更简单了 不需要 daydiff dayadd

[白云任去留]

周范围(按国外算法，一周从周天开始)： int week = (int)DateTime.Now.DayOfWeek; 起始日期: DateTime.Now.AddDays(-week).toString("yyyy-MM-dd") 结束日期: DateTime.Now.AddDays(7 - (week+1)).toString("yyyy-MM-dd")

Response.Write(DateTime.Now.AddDays(-(int)DateTime.Now.DayOfWeek).ToShortDateString() + "<br/>" + DateTime.Now.AddDays(6 - (int)DateTime.Now.DayOfWeek).ToShortDateString());
