EWS(Exchange Web services)时区问题解决

最近有项目用到EWS API的发起会议,时区一起无法找到正确解决办法,如果时区不对,那么会议时间和UTC时间会冲突的。显示如下错误:

经过MSDN资料查找,原来可以设置时区的。

TimeZoneInfo.FindSystemTimeZoneById("China Standard Time")表示北京时间
TimeZoneInfo.FindSystemTimeZoneById("Central Standard Time");表示美国中部时间
依次类推

代码如下:

 ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP1, TimeZoneInfo.FindSystemTimeZoneById("China Standard Time"));
             service.Credentials = new NetworkCredential("XXXX", "XXXX", "XXX.com");
                service.Url = new Uri("https://XXX.XXX.com/EWS/Exchange.asmx");
            
            //实例化一个Appointment
            Appointment appointment = new Appointment(service);
            //约会主题
            appointment.Subject = "测试UTC,设置了北京时间?";
            //约会内容
            appointment.Body = "测试,设置了北京时间";
            //约会开始时间2010-6-1 12:30:00
            appointment.Start = new DateTime(2012, 11, 29, 08, 30, 0);
            //约会结束
            appointment.End = appointment.Start.AddDays(5);
            //约会的位置
            appointment.Location="216会议室";
            //添加与会者
            
            appointment.RequiredAttendees.Add("XXX@XXXX.com");
           
            // 从2010-6-1 12:30:00开始每周举行一次
            //appointment.Recurrence = new Recurrence.WeeklyPattern(appointment.Start,1,DayOfWeek.Saturday);
            //可以设置发送通知的方式,如:
            //Appointment.Save(SendInvitationsMode.SendOnlyToAll)
            appointment.Save();
            MessageBox.Show("ok");

正确效果图如下:
