从存储在Exchange中的ContactInfo获取Smtp电子邮件

Question

我正在为我的Outlook加载项使用VSTO。目前我正在处理所有Outlook联系人的电子邮件地址。如果EmailAddress1Type是“SMTP”，则ContactInfo的实例没有问题。

但如何获取Exchange联系人的电子邮件地址（Email1AddressType =“EX”）？

救赎图书馆对我来说并不是解决方案，因为解决这个问题很昂贵。

谢谢你在前进，

这里是MSDN reference link和相应的示例代码：

private const string Email1EntryIdPropertyAccessor = "http://schemas.microsoft.com/mapi/id/{00062004-0000-0000-C000-000000000046}/80850102"; 

PropertyAccessor propertyAccessor = contactItem.PropertyAccessor; 
object rawPropertyValue = propertyAccessor.GetProperty(Email1EntryIdPropertyAccessor); 
string recipientEntryID = propertyAccessor.BinaryToString(rawPropertyValue); 
Recipient recipient = contactItem.Application.Session.GetRecipientFromID(recipientEntryID); 
if (null == recipient) 
    throw new InvalidOperationException(); 

bool wasResolved = recipient.Resolve(); 
if (!wasResolved) 
    throw new InvalidOperationException(); 
ExchangeUser exchangeUser = recipient.AddressEntry.GetExchangeUser(); 
string smtpAddress = exchangeUser.PrimarySmtpAddress;
