Microsoft.Office.Interop.Outlook.SelectNamesDialog get电子邮件组

目前我正在使用Outlook Microsoft.Office.Interop.Outlook.SelectNamesDialog获取Contact，但是在地址簿 (Microsoft.Office.Interop.Outlook.SelectNamesDialog)中还有组电子邮件。

我在找一种方法来获取邮件组中的所有电子邮件？

Answer 1

下面是如何通过Exchange分发列表通过SelectNamesDialog选择检索成员的示例。

Outlook.SelectNamesDialog names =  Globals.ThisAddIn.Application.Session.GetSelectNamesDialog();
names.SetDefaultDisplayMode(Outlook.OlDefaultSelectNamesDisplayMode.olDefaultMembers);
names.ForceResolution = true;
names.Caption = "Please selection something";
if (names.Display())
{
    Outlook.Recipients recipients = names.Recipients;
    foreach (Outlook.Recipient recipient in recipients)
    {
        Outlook.AddressEntry entry = recipient.AddressEntry;
        if (entry.AddressEntryUserType == Outlook.OlAddressEntryUserType.olExchangeDistributionListAddressEntry)
        {
            Outlook.ExchangeDistributionList list = entry.GetExchangeDistributionList();
            Outlook.AddressEntries members = list.GetExchangeDistributionListMembers();
            foreach (Outlook.AddressEntry member in members)
            {
                Outlook.ExchangeUser user = member.GetExchangeUser();
                string address = user.PrimarySmtpAddress;
            }
        }
    }
}

一旦您有了地址，就很容易将它们添加到集合中。

对于通讯录文件夹中的通讯组列表，前面的答案将失败。您所需要做的就是访问Recipient.AddressEntry.Members集合(准备处理nulls)。
