实现如下目的：
1、录入一个同学的出生日期,如：2009年3月6日
2、输出那天是星期几,如：星期五

[nj_1st_excellence]

获取输入的日期是一周中的第几天
Convert.ToDateTime("2009-03-06").DayOfWeek;
然后再排出是星期几

[CutBug]

string str = "2009年3月6日";
        Match m = Regex.Match(str, @"(\d+)\D(\d+)\D(\d+)\D");
        if (m.Success)
        {
            string[] week={"日","一","二","三","四","五","六"};
            DateTime d = new DateTime(Convert.ToInt32(m.Groups[1].Value), Convert.ToInt32(m.Groups[2].Value), Convert.ToInt32(m.Groups[3].Value));
            Response.Write("当天是星期" + week[(int)d.DayOfWeek]);
        }

[阿非]

        string dateStr="2009年3月9日";
        DateTime dt;
        DateTime.TryParse(dateStr, out dt);
        string[] week ={ "日", "一", "二", "三", "四", "五", "六" };
        Response.Write( dateStr + " 是星期" + week[(int)dt.DayOfWeek]);

顶下，Match m = Regex.Match(str, @"(\d+)\D(\d+)\D(\d+)\D");没用过

[阿非]

        string dateStr="2009年3月9日";
        DateTime dt;
        if(DateTime.TryParse(dateStr, out dt))
        {
            string[] week ={ "日", "一", "二", "三", "四", "五", "六" };
            Response.Write( dateStr + " 是星期" + week[(int)dt.DayOfWeek]);
        }
