C# exchange server 获取会议室预约列表

Question

我正在尝试与 EWS Managed API 一起获取会议室列表，并为每个房间查看一周的预约列表。

我看到了Get room lists by using EWS in Exchange 并且 Get appointments and meetings by using EWS in Exchange

我测试了第一个 link，我得到了 0 个房间。
同样对于第二个 link 它提供了当前用户日历但没有会议。

我需要 3 样东西：

1) 获取我组织中的会议室列表。
2) 获取每个房间的会议日历（X 天）。
3) 对于每次会议，谁组织了会议。

我找不到获取此信息的 API。

经过大量搜索并感谢 this post 我找到了问题 #1 和 #2

的答案

1) 获取组织中的所有会议室：

 string filter = "(&(objectClass=*)(msExchRecipientDisplayType=7))";
 //Assembly System.DirectoryServices.dll
 DirectorySearcher search = new DirectorySearcher(filter);
 List<AttendeeInfo> rooms = new List<AttendeeInfo>();  
 foreach (SearchResult result in search.FindAll())
            {
                ResultPropertyCollection r = result.Properties;
                DirectoryEntry entry = result.GetDirectoryEntry();
                // entry.Properties["displayName"].Value.ToString() will bring the room name
                rooms.Add(new AttendeeInfo(entry.Properties["mail"].Value.ToString().Trim()));                 
            }

2) 获取每个房间的会议日历（2 天）：

List<AttendeeInfo> attend = new List<AttendeeInfo>();
foreach (AttendeeInfo inf in rooms)
     {
       attend.Clear();
       attend.Add(inf.SmtpAddress);

       AvailabilityOptions options = new AvailabilityOptions();
       options.MaximumSuggestionsPerDay = 48;
       // service is ExchangeService object contains your authentication with exchange server
       GetUserAvailabilityResults results = service.GetUserAvailability(attend, new TimeWindow(DateTime.Now, DateTime.Now.AddDays(2)), AvailabilityData.FreeBusyAndSuggestions, options);

        foreach (AttendeeAvailability attendeeAvailability in results.AttendeesAvailability)
                {
                    Console.WriteLine();
                    Console.WriteLine();
                    if (attendeeAvailability.ErrorCode == ServiceError.NoError)
                    {
                        foreach (Microsoft.Exchange.WebServices.Data.CalendarEvent calendarEvent in
                        attendeeAvailability.CalendarEvents)
                        {
                            Console.WriteLine("Calendar event");
                            Console.WriteLine(" Starttime: " + calendarEvent.StartTime.ToString());
                            Console.WriteLine(" Endtime: " + calendarEvent.EndTime.ToString());
                            if (calendarEvent.Details != null)
                            {
                                Console.WriteLine(" Subject:" + calendarEvent.Details.Subject);

                            }
                        }
                    }
                }
            }

关于问题 #3，获取此信息并不简单，因为它是私人信息，作为普通用户，您无权查看它。
