如何设置Microsoft.Exchange.WebServices.Data。属性更新()时的约会?

outlook-2013 exchange-server-2010 exchangewebservices c#

问题

我有一个带有Microsoft.Exchange的Visual Studio 2015控制台应用程序。安装了WebServices v2.2.0 NuGet包。我正在尝试创建约会、更新约会并取消约会,同时在日历邀请中自动生成的“When”字符串中保留正确的时区身体当前,初始创建具有正确的时区,但任何后续更新都会导致时区恢复为UTC。

注意:我们有一台Exchange 2010服务器,使用Outlook 2013客户端。

代码示例

using System;
using System.Globalization;
using Microsoft.Exchange.WebServices.Data;

namespace EWSTesting
{
    class Program
    {
        private const string EmailServer = ""; //replace with your Exchange server
        private const string EmailAddress = ""; //replace with your email

        static void Main(string[] args)
        {
            Console.WriteLine("Current Timezone: " + TimeZoneInfo.Local.DisplayName);

            var exchangeService = new ExchangeService(ExchangeVersion.Exchange2010, TimeZoneInfo.Local)
            {
                PreferredCulture = new CultureInfo("en-US"),
                Url = new Uri(EmailServer),
                UseDefaultCredentials = true
            };

            Console.WriteLine("exchangeService.TimeZone.DisplayName: " + exchangeService.TimeZone.DisplayName);

            var startDate = DateTime.Today;
            var endDate = startDate.AddHours(1);

            //Create initial appointment
            var appointment = new Appointment(exchangeService)
            {
                Subject = "Testing Appointments",
                Body = "Testing Appointments Body",
                Location = "Test Location",
                LegacyFreeBusyStatus = LegacyFreeBusyStatus.Busy,
                Sensitivity = Sensitivity.Private,
                Start = startDate,
                End = endDate
            };
            appointment.OptionalAttendees.Add(EmailAddress);
            appointment.Save(SendInvitationsMode.SendOnlyToAll);

            Console.WriteLine("exchangeService.TimeZone.DisplayName: " + exchangeService.TimeZone.DisplayName);

            var appointmentId = appointment.Id;

            Console.WriteLine("Pause to check inbox 'When' value on invite");
            Console.ReadLine();

            appointment = Appointment.Bind(exchangeService, appointmentId);

            appointment.Load(new PropertySet(PropertySet.FirstClassProperties)
            {
                AppointmentSchema.StartTimeZone,
                AppointmentSchema.EndTimeZone,
                AppointmentSchema.TimeZone
            });

            appointment.Body = "Body Updated Successfully";
            appointment.Update(ConflictResolutionMode.AlwaysOverwrite, SendInvitationsOrCancellationsMode.SendOnlyToAll);

            Console.WriteLine("exchangeService.TimeZone.DisplayName: " + exchangeService.TimeZone.DisplayName);
            Console.WriteLine("appointment.StartTimeZone.DisplayName: " + appointment.StartTimeZone.DisplayName);
            Console.WriteLine("appointment.EndTimeZone.DisplayName: " + appointment.EndTimeZone.DisplayName);
            Console.WriteLine("appointment.TimeZone: " + appointment.TimeZone);

            Console.WriteLine();
            Console.WriteLine("Pause to check updated inbox 'When' value on invite");
            Console.ReadLine();

            appointment = Appointment.Bind(exchangeService, appointmentId);

            appointment.Load(new PropertySet(PropertySet.FirstClassProperties)
            {
                AppointmentSchema.StartTimeZone,
                AppointmentSchema.EndTimeZone,
                AppointmentSchema.TimeZone
            });

            Console.WriteLine("exchangeService.TimeZone.DisplayName: " + exchangeService.TimeZone.DisplayName);
            Console.WriteLine("appointment.StartTimeZone.DisplayName: " + appointment.StartTimeZone.DisplayName);
            Console.WriteLine("appointment.EndTimeZone.DisplayName: " + appointment.EndTimeZone.DisplayName);
            Console.WriteLine("appointment.TimeZone: " + appointment.TimeZone);

            appointment.CancelMeeting();

            Console.WriteLine("Appointment Deleted");
            Console.ReadLine();
        }
    }
}

以上代码的结果

初始邀请(正确时区)

Initial Invite

更新的约会(正文中的时区不正确)

Body Updated

预约取消(正文中的时区不正确)

Appointment Cancelled

提供的代码的控制台结果

Console Result

我在找什么

我不需要在邀请函正文中附加这个额外的“何时”(上图中用红色下划线)。要么我想完全删除它(首选),要么我想在任何更新中更正它。

问题似乎是EWS 2.2.0 DLL中的一个错误,时区SOAP头未添加到Update()和CancelMeeting()Exchange事务中。下面的代码通过手动附加正确的头来解决此问题。

对于Update():

exchangeService.OnSerializeCustomSoapHeaders += service_OnSerializeCustomSoapHeaders;
appointment.Update(ConflictResolutionMode.AlwaysOverwrite, SendInvitationsOrCancellationsMode.SendOnlyToAll);
exchangeService.OnSerializeCustomSoapHeaders -= service_OnSerializeCustomSoapHeaders;

对于取消会议():

exchangeService.OnSerializeCustomSoapHeaders += service_OnSerializeCustomSoapHeaders;
appointment.CancelMeeting();
exchangeService.OnSerializeCustomSoapHeaders -= service_OnSerializeCustomSoapHeaders;

活动实施:

static void service_OnSerializeCustomSoapHeaders(XmlWriter writer)
{
    writer.WriteRaw(Environment.NewLine + "    <t:TimeZoneContext><t:TimeZoneDefinition Id=\"" + TimeZoneInfo.Local.StandardName + "\"/></t:TimeZoneContext>" + Environment.NewLine);
}
