从 EWS 访问 Outlook 用户属性 [英] Access Outlook user properties from EWS

问题描述

我正在尝试创建一个使用 EWS api 访问联系人的应用程序.

I'm trying to create an application that use the EWS api to access contacts.

在此过程中，我需要查看 Outlook 用户属性之一，但在使用 EWS 时我看不到如何获得它.目前我刚刚尝试...

I need to look at one of the outlook user properties in this process but I cant see how to get it at using EWS. At the moment ive just tried...

service.Url = new Uri("https://url/ews/Exchange.asmx");
service.Credentials = new WebCredentials("credentials");
var results = service.FindItems(folderId, new ItemView(100));
foreach (var item in results)
{
     Contact contact = item as Contact;
     foreach (var prop in contact.ExtendedProperties)
     {
            Console.WriteLine(prop.Value.ToString());
     }
}

编译和执行没有问题，但对于每个联系人，ExtendedProperties 计数为 0，在 Outlook 中约为 30.

Which compiles and executes without a problem, but for every contact the ExtendedProperties count is 0 which in outlook its about 30.

那么我怎样才能获得我正在寻找的属性?

So how can I get the properties I'm looking for?

仅供参考.我使用的是exhcnage 2007.

Just an FYI. Im using exhcnage 2007.

谢谢.

推荐答案

您需要定义想要获取的属性 - EWS 不允许您枚举用户属性.

You need to define the properties you want to get - EWS does not permit you to enumerate user properties.

用户属性位于命名空间 PublicStrings 中.

The Userproperties are in the namespace PublicStrings.

private static readonly ExtendedPropertyDefinition CustomProperty = new ExtendedPropertyDefinition(DefaultExtendedPropertySet.PublicStrings, "MyCustomProperty", MapiPropertyType.String);

然后您可以在 FindItems 请求中使用该定义:

You can then use the definition in a FindItems request:

var items = service.FindItems(WellKnownFolderName.Inbox, new ItemView(100) { PropertySet =   new PropertySet(BasePropertySet.FirstClassProperties, CustomProperty)});
