使用Exchange Web服务API提取Exchange 2007公共日历约会

Question

我们为在Exchange 2007公用文件夹中设置的公司设置公共日历。我可以使用下面的代码检索当天的个人日历约会。我在网上搜索了高和低，我找不到某人从公共文件夹日历中检索日历信息的示例。

它似乎应该是可行的，但我不能为我的生活得到它的工作。我如何修改下面的代码来访问日历？我不想通过asp.net创建任何约会，只需检索一个简单的列表。我也接受任何其他建议。谢谢。

ADDED BOUNTY
- 我不能有史以来需要做到这一点的唯一的人。让我们为后代解决这个问题。

再次更新由于无知
- 我忘了，我工作的项目是.NET 2.0（非常重要的你不觉得？）。

*将我的代码解决方案BELOW *
- 我已经取代与结束了工作的代码我原来的代码示例。非常感谢Oleg提供的代码来查找公用文件夹，这是最难的部分..我使用这里的例子修改了代码http://msexchangeteam.com/archive/2009/04/21/451126.aspx以使用更简单的FindAppointments方法。

这个简单的例子返回一个html字符串与约会，但你可以使用它作为一个基础，根据需要进行自定义。你可以在下面的答案中看到我们的来回。

就像这里承诺的是一个代码示例。我使用the Microsoft Exchange Web Services (EWS) Managed API 1.0并建议您也这样做。我在代码中包含

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

namespace ExchangePublicFolders { 
    class Program { 
     static FolderId FindPublicFolder (ExchangeService myService, FolderId baseFolderId, 
      string folderName) { 

      // We will search using paging. We will use page size 10 
      FolderView folderView = new FolderView (10,0); 
      folderView.OffsetBasePoint = OffsetBasePoint.Beginning; 
      // we will need only DisplayName and Id of every folder 
      // se we'll reduce the property set to the properties 
      folderView.PropertySet = new PropertySet (FolderSchema.DisplayName, 
       FolderSchema.Id); 

      FindFoldersResults folderResults; 
      do { 
       folderResults = myService.FindFolders (baseFolderId, folderView); 

       foreach (Folder folder in folderResults) 
        if (String.Compare (folder.DisplayName, folderName, StringComparison.OrdinalIgnoreCase) == 0) 
         return folder.Id; 

       if (folderResults.NextPageOffset.HasValue) 
        // go to the next page 
        folderView.Offset = folderResults.NextPageOffset.Value; 
      } 
      while (folderResults.MoreAvailable); 

      return null; 
     } 

     static void MyTest() { 
      // IMPORTANT: ExchangeService is NOT thread safe, so one should create an instance of 
      // ExchangeService whenever one needs it. 
      ExchangeService myService = new ExchangeService (ExchangeVersion.Exchange2007_SP1); 

      myService.Credentials = new NetworkCredential ("MyUser@corp.local", "myPassword00"); 
      myService.Url = new Uri ("http://mailwebsvc-t.services.local/ews/exchange.asmx"); 
      // next line is very practical during development phase or for debugging 
      myService.TraceEnabled = true; 

      Folder myPublicFoldersRoot = Folder.Bind (myService, WellKnownFolderName.PublicFoldersRoot); 
      string myPublicFolderPath = @"OK soft GmbH (DE)\Gruppenpostfächer\_Template - Gruppenpostfach\_Template - Kalender"; 
      string[] folderPath = myPublicFolderPath.Split('\\'); 
      FolderId fId = myPublicFoldersRoot.Id; 
      foreach (string subFolderName in folderPath) { 
       fId = FindPublicFolder (myService, fId, subFolderName); 
       if (fId == null) { 
        Console.WriteLine ("ERROR: Can't find public folder {0}", myPublicFolderPath); 
        return; 
       } 
      } 

      // verify that we found 
      Folder folderFound = Folder.Bind (myService, fId); 
      if (String.Compare (folderFound.FolderClass, "IPF.Appointment", StringComparison.Ordinal) != 0) { 
       Console.WriteLine ("ERROR: Public folder {0} is not a Calendar", myPublicFolderPath); 
       return; 
      } 

      CalendarFolder myPublicFolder = CalendarFolder.Bind (myService, 
       //WellKnownFolderName.Calendar, 
       fId, 
       PropertySet.FirstClassProperties); 

      if (myPublicFolder.TotalCount == 0) { 
       Console.WriteLine ("Warning: Public folder {0} has no appointment. We try to create one.", myPublicFolderPath); 

       Appointment app = new Appointment (myService); 
       app.Subject = "Writing a code example"; 
       app.Start = new DateTime (2010, 9, 9); 
       app.End = new DateTime (2010, 9, 10); 
       app.RequiredAttendees.Add ("oleg.kiriljuk@ok-soft-gmbh.com"); 
       app.Culture = "de-DE"; 
       app.Save (myPublicFolder.Id, SendInvitationsMode.SendToNone); 
      } 

      // We will search using paging. We will use page size 10 
      ItemView viewCalendar = new ItemView (10); 
      // we can include all properties which we need in the view 
      // If we comment the next line then ALL properties will be 
      // read from the server. We can see there in the debug output 
      viewCalendar.PropertySet = new PropertySet (ItemSchema.Subject); 
      viewCalendar.Offset = 0; 
      viewCalendar.OffsetBasePoint = OffsetBasePoint.Beginning; 
      viewCalendar.OrderBy.Add (ContactSchema.DateTimeCreated, SortDirection.Descending); 

      FindItemsResults<Item> findResultsCalendar; 
      do { 
       findResultsCalendar = myPublicFolder.FindItems (viewCalendar); 

       foreach (Item item in findResultsCalendar) { 
        if (item is Appointment) { 
         Appointment appoint = item as Appointment; 
         Console.WriteLine ("Subject: \"{0}\"", appoint.Subject); 
        } 
       } 

       if (findResultsCalendar.NextPageOffset.HasValue) 
        // go to the next page 
        viewCalendar.Offset = findResultsCalendar.NextPageOffset.Value; 
      } 
      while (findResultsCalendar.MoreAvailable); 
     } 
     static void Main (string[] args) { 
      MyTest(); 
     } 
    } 
} 

最多评论您应该更新字符串myPublicFolderPath与您的公共文件夹压延机的价值。我设置了myService.TraceEnabled = true，它可以产生带有调试信息的长输出。您应该删除生产线。

已更新：您可以在Create new calendar system support in Exchange OWA中找到一些其他链接。如果您还没有看到视频，并且您想使用Exchange Web服务，我会建议您在那里观看。它可以节省你的时间在未来。

我做了类似的事情，对于Exchange 2003，但使用WebDAV搜索方法（http://msdn.microsoft.com/en-us/library/aa143053%28v=EXCHG.65%29.aspx）。
