Microsoft.Office.Interop.Outlook.SelectNamesDialog获取电子邮件组

Question

目前我正在使用Outlook Microsoft.Office.Interop.Outlook.SelectNamesDialog来获取通讯录，但在地址簿（Microsoft.Office.Interop.Outlook.SelectNamesDialog）中有组电子邮件也。

我正在寻找一种方法来获取该电子邮件组中的所有电子邮件？

Answer 1

以下是有关如何通过SelectNamesDialog选择从 Exchange分发列表检索成员的示例。

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;
            }
        }
    }
}

获得地址后，可以很容易地将它们添加到集合中。

“联系人”文件夹中的分发列表的上一个答案将失败。 您需要做的就是访问Recipient.AddressEntry.Members集合（准备处理空值）。
