            try
            {
                int x = GetSystemDefaultLCID();
                SetLocaleInfo(x, LOCALE_STIME, "HH:mm:ss");        //时间格式 
                SetLocaleInfo(x, LOCALE_SSHORTDATE, "yyyy-MM-dd");   //短日期格式

            }
            catch (Exception ex)
            {
                Console.WriteLine(ex);
