sharepoint-2010 – 在更新约会时TimeZone更改为UTC

2019年8月3日 291次阅读

我正在使用EWS 1.2发送约会.在创建新的约会时,TimeZone正在显示通知邮件,但在更新相同的约会时,TimeZone将重置为UTC.

任何人都可以帮我解决这个问题吗？

以下是复制问题的示例代码：

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP1, TimeZoneInfo.FindSystemTimeZoneById("Eastern Standard Time"));
service.Credentials = new WebCredentials("ews_calendar", PASSWORD, "acme");
service.Url = new Uri("https://acme.com/EWS/Exchange.asmx");

Appointment newAppointment = new Appointment(service);
newAppointment.Subject = "Test Subject";
newAppointment.Body = "Test Body";
newAppointment.Start = new DateTime(2012, 03, 27, 17, 00, 0);
newAppointment.End = newAppointment.Start.AddMinutes(30);
newAppointment.RequiredAttendees.Add("tin.tin@acme.com");

//Attendees get notification mail for this appointment using (UTC-05:00) Eastern Time (US & Canada) timezone
//Here is the notification content received by attendees:
//When: Tuesday, March 27, 2012 5:00 PM-5:30 PM. (UTC-05:00) Eastern Time (US & Canada)
newAppointment.Save(SendInvitationsMode.SendToAllAndSaveCopy);

// Pull existing appointment
string itemId = newAppointment.Id.ToString();

Appointment existingAppointment = Appointment.Bind(service, new ItemId(itemId));

//Attendees get notification mail for this appointment using UTC timezone
//Here is the notification content received by attendees:
//When: Tuesday, March 27, 2012 11:00 PM-11:30 PM. UTC
existingAppointment.Update(ConflictResolutionMode.AlwaysOverwrite, SendInvitationsOrCancellationsMode.SendToAllAndSaveCopy);

最佳答案 在绑定existingAppointment时,您需要设置AppointmentSchema.StartTimeZone并将其绑定为属性对象的一部分,如
illustrated here：

// Get an existing calendar item, requesting the Id, Start, and 
//  StartTimeZone properties.
PropertySet props = new PropertySet(
      AppointmentSchema.Id, 
      AppointmentSchema.Start, 
      AppointmentSchema.StartTimeZone);
Appointment appt = Appointment.Bind(service, new ItemId("AQMkA="), props);

似乎默认的绑定时区是UTC.
