EWS：我如何知道谁在会议室日历中直接创建了会议？

Question

当用户直接在会议室的日历中创建会议时，组织者字段设置为房间的名称（没有创建会议的用户）。是否可以获取使用 EWS 2010 创建会议的用户的姓名？

Answer 1

如果您检查应显示创建者姓名的发件人扩展属性（代表发送则为邮箱名称）例如

Mailbox MeetingRoom = new Mailbox("room@domain.com");
FindItemsResults<Appointment> appts = service.FindAppointments(new FolderId(WellKnownFolderName.Calendar,MeetingRoom),new CalendarView(DateTime.Now,DateTime.Now.AddMonths(1),1000));
ExtendedPropertyDefinition PR_SENDER_EMAIL_ADDRESS_W = new ExtendedPropertyDefinition(0x0C1F,MapiPropertyType.String);
ExtendedPropertyDefinition PR_SENDER_ADDRTYPE_W = new ExtendedPropertyDefinition(0x0C1E,MapiPropertyType.String);
PropertySet psProps = new PropertySet();
psProps.Add(PR_SENDER_ADDRTYPE_W);
psProps.Add(PR_SENDER_EMAIL_ADDRESS_W);
if(appts.Items.Count > 0){
    service.LoadPropertiesForItems(from Item item in appts select item,psProps);
    foreach(Appointment apt in appts){
        Object SenderAddressType = null;
        Object SenderAddress = null;
        if(apt.TryGetProperty(PR_SENDER_ADDRTYPE_W,out SenderAddressType)){
            if(apt.TryGetProperty(PR_SENDER_EMAIL_ADDRESS_W,out SenderAddress)){
                if(SenderAddressType.ToString() == "EX")
                {
                    NameResolutionCollection nccol = service.ResolveName(SenderAddress.ToString(),ResolveNameSearchLocation.DirectoryOnly,true);
                    if(nccol.Count == 1){
                        Console.WriteLine(nccol[0].Mailbox.Address);
                    }
                }
                else
                {
                    Console.WriteLine(SenderAddress);
                }
            }
        }
    }
}
