to get the value of the week in English, but most people to convert Chinese
DateTime.Now.DayOfWeek.ToString (); // Thursday week acquired
conversion:
System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetDayName(DateTime.Now.DayOfWeek)
一整条语句：
string filedate = DateTime.Now.Year.ToString() + "/" + DateTime.Now.Month.ToString() + "/" + DateTime.Now.Day.ToString() + "/" + System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetDayName(DateTime.Now.DayOfWeek) + "/" + DateTime.Now.ToString("hh:mm:ss");
