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

问题描述

我试图创建使用EWS API来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.

我需要看看在这个过程中Outlook用户的属性之一，但我不能看到如何使用在EWS得到它。目前，香港专业教育学院刚刚试过...

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());
     }
}

哪个编译并没有问题执行，但对于每一个联系ExtendedProperties计数为0，这在其展望30。

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

所以，我怎样才能得到我想要？

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

只是一个供参考。即时通讯使用exhcnage 2007。

Just an FYI. Im using exhcnage 2007.

感谢。

推荐答案

您需要定义你想要得到的属性 - 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.

Userproperties是在命名空间PublicStrings

The Userproperties are in the namespace PublicStrings.

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

您可以再使用的定义在FindItems要求：

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)});
