以编程方式从 Exchange Outlook 联系人获取 Internet 电子邮件地址? [英] Getting the Internet e-mail address from an Exchange Outlook Contact programmatically?

问题描述

我正在尝试从与 Exchange 连接的 Outlook 中读出 Internet 格式的地址.我从 Outlook 联系人中读取了所有联系人，即不是从全局通讯簿 (GAB) 中读取的，问题是对于存储在 Exchange GAB 中的联系人中的所有用户，我只能读取 X.500 格式在这种情况下没有用的地址.对于不在 Exchange 服务器域中的所有手动添加的联系人，Internet 地址将按预期导出.

I’m trying to read out the Internet formatted address from an Exchange connected Outlook. I read all contacts from the Outlook Contacts, i.e. not from the Global Address Book (GAB), and the problem is that for all users that are stored in Contacts from the Exchange GAB I’ve only managed to read out the X.500 formatted address which is not useful in this case. For all manually added contacts that are not in the domain of the Exchange server, the Internet address is exported as expected.

基本上我使用以下代码片段来枚举联系人:

Basically I’ve used the following code snippet to enumerate the Contacts:

static void Main(string[] args)
{
    var outlookApplication = new Application();
    NameSpace mapiNamespace = outlookApplication.GetNamespace("MAPI");
    MAPIFolder contacts = mapiNamespace.GetDefaultFolder(OlDefaultFolders.olFolderContacts);

    for (int i = 1; i < contacts.Items.Count + 1; i++)
    {
        try
        {
            ContactItem contact = (ContactItem)contacts.Items[i];
            Console.WriteLine(contact.FullName);
            Console.WriteLine(contact.Email1Address);
            Console.WriteLine(contact.Email2Address);
            Console.WriteLine(contact.Email3Address);
            Console.WriteLine();
        }
        catch (System.Exception e) { }
    }
    Console.Read();
}

有没有办法提取互联网地址而不是X.500?

Is there any way to extract the Internet address instead of the X.500?

推荐答案

您需要从 ContactItem 转换为 AddressEntry - 一次一个电子邮件地址.

You need to convert from ContactItem to AddressEntry - one email address at a time.

为此，您需要通过 Recipient 对象模型访问 AddressEntry.检索实际收件人 EntryID 的唯一方法是通过 利用PropertyAccessorContactItem.

To do this, you need to access the AddressEntry via the Recipient object model. The only way to retrieve the actual Recipient EntryID is by leveraging the PropertyAccessor of the ContactItem.

const string Email1EntryIdPropertyAccessor = "http://schemas.microsoft.com/mapi/id/{00062004-0000-0000-C000-000000000046}/80850102";
string address = string.Empty;
Outlook.Folder folder = this.Application.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderContacts) as Outlook.Folder;
foreach (var contact in folder.Items.Cast<Outlook.ContactItem>().Where(c=>!string.IsNullOrEmpty(c.Email1EntryID)))
{
    Outlook.PropertyAccessor propertyAccessor = contact.PropertyAccessor;
    object rawPropertyValue = propertyAccessor.GetProperty(Email1EntryIdPropertyAccessor);
    string recipientEntryID = propertyAccessor.BinaryToString(rawPropertyValue);
    Outlook.Recipient recipient = this.Application.Session.GetRecipientFromID(recipientEntryID);
    if (recipient != null && recipient.Resolve() && recipient.AddressEntry != null)
        address = recipient.AddressEntry.GetExchangeUser().PrimarySmtpAddress;
}
