我们在Exchange 2007公用文件夹中设置了公司的公共日历。我可以使用下面的代码检索当天的个人日历约会。我在网上搜索了高低，我找不到某人从公共文件夹日历中检索日历信息的例子。
它似乎应该是可行的，但我不能为我的生活让它工作。如何修改以下代码以访问日历？我对通过asp.net创建任何约会不感兴趣，只是检索一个简单的列表。我也对任何其他建议持开放态度。感谢。
ADDED BOUNTY
- 我不可能是唯一需要这样做的人。让我们为后代解决这个问题。
由于无知而再次更新
- 我没有提到我正在研究的项目是.NET 2.0（你觉得非常重要吗？）。
*在下面添加我的代码解决方案*
- 我已经用最终工作的代码替换了我的原始代码示例。非常感谢Oleg提供了查找公共文件夹的代码，这是最难的部分。我使用这里的http://msexchangeteam.com/archive/2009/04/21/451126.aspx示例修改了代码，以使用更简单的FindAppointments方法。
这个简单的示例返回带约会的html字符串，但您可以将其用作基础来根据需要进行自定义。您可以在下面的答案中看到我们的来回。

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并建议你也这样做。我在代码中包含的评论最多

folderView.PropertySet = new PropertySet (FolderSchema.DisplayName,
FolderSchema.Id);
FindFoldersResults folderResults;

您应该使用公开日历文件夹将字符串myPublicFolderPath更新为该值。我设置myService.TraceEnabled = true，它产生带有调试信息的长输出。您应该删除生产线。
更新：您可以在Create new calendar system support in Exchange OWA中找到一些其他链接。如果您还没有看过这些视频并且想要使用Exchange Web服务，我建议您在那里观看。它可以节省你将来的时间。

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