EWS-扩展属性搜索 [英] EWS - Extended Property Search

问题描述

大家好，

我尝试了多种方法来搜索日历约会中的扩展属性，但没有成功.我正在使用VS 2008中的C#(Web服务).请问指向正确的方向吗?

[edit]
我有一个VSTO应用程序，该应用程序将Guid放入每个约会用户属性中.当使用EWS时，我想检索该资源/会议室的所有扩展属性.我正在使用C#(Web服务项目)，VS2008和Exchange2010.因此，首先可以这样做吗?如果是这样，我该如何实现呢?
[edit]

通过执行以下操作，我确实获得了资源中所有约会的列表，但是当我调用ExtendedProperty时，每个属性的值都为null，并且我知道其中两个项目都有值.

Hi all,

I have tried various ways to search for extended properties within calendar appointment, without any success. I am making use of C# (Web Services), VS 2008. Can any please point me in the right direction?

[edit]
I have a VSTO application that puts a Guid into each Appointment user property. When by making use of EWS I want to retrieve all the Extended Properties for that resource / boardroom. I am making use of C# (Web Service Project), VS2008 and Exchange 2010. So, first of all, is it possible to do this? And if so, how can I achieve this?
[edit]

I do get a list of all appointment within the resource by performing the following, but when I call the ExtendedProperty the value is null for each one, and I know for two of the items there are values.

foreach (ItemType it in items.Items)
{
   if (it is CalendarItemType)
   {
      CalendarItemType cal = (CalendarItemType)it;
      if (cal.ExtendedProperty != null)
          tmp.Add(new ExtendedAppointmentData()
              {
                  EndDate = cal.End,
                  StartDate = cal.Start,
                  EventID = new Guid(cal.ExtendedProperty[0].Item.ToString()),
                  AppointmentStatus = cal.LegacyFreeBusyStatus.ToString()
              });
    }
}

提前非常感谢.
亲切的问候，

Many thanks in advance.

以下代码转储"解决了我的问题(仔细研究了属性DistinguishedPropertySetType.PublicStrings带来了很大的不同！) :

The following ''code dump'' solved my problem (have a close look at the property DistinguishedPropertySetType.PublicStrings made a world of difference!!):
