任意日期间的任意星期指定,做标记.
            DateTime bTime = DateTime.Parse("2007-1-1");
            DateTime eTime = DateTime.Parse("2007-2-1");
            string[] arrStr = { "sunday", "tuesday" };            int dateLen = ((TimeSpan)(eTime- bTime)).Days ;
            for (int i = 0; i < dateLen; i++)
            {
                for (int j = 0; j < arrStr.Length; j++)
                {
                    if (bTime.AddDays(i).DayOfWeek.ToString().ToLower() == arrStr[j]) {
                        Response.Write("*:");
                        break;

                Response.Write(bTime.AddDays(i).ToString() + "<br>");
