处理通讯组列表

使用 Aspose.Email API 可以创建一个分发列表，它是多个联系人集合。分发列表可以以 Outlook MSG 格式保存到磁盘，并且可以通过在 Microsoft Outlook 中打开进行查看/操作。

创建并保存通讯组列表

以下代码片段展示了如何创建并保存通讯组列表。

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
// The path to the File directory.
String dataDir = "outlook/";

String displayName1 = "Sebastian Wright";
String email1 = "[e-mail]";

String displayName2 = "Wichert Kroos";
String email2 = "[e-mail]";

String strEntryId1;
String strEntryId2;

// Create distribution list from contacts
try (PersonalStorage personalStorage = PersonalStorage.create(dataDir + "CreateDistributionListInPST_out.pst", FileFormatVersion.Unicode)) {
    // Add the contact folder to pst
    FolderInfo contactFolder = personalStorage.createPredefinedFolder("Contacts", StandardIpmFolder.Contacts);

    // Create contacts
    strEntryId1 = contactFolder.addMapiMessageItem(new MapiContact(displayName1, email1));
    strEntryId2 = contactFolder.addMapiMessageItem(new MapiContact(displayName2, email2));

    // Create distribution list on the base of the created contacts
    MapiDistributionListMember member1 = new MapiDistributionListMember(displayName1, email1);
    member1.setEntryIdType(MapiDistributionListEntryIdType.Contact);
    member1.setEntryId(Base64.getDecoder().decode(strEntryId1));

    MapiDistributionListMember member2 = new MapiDistributionListMember(displayName2, email2);
    member2.setEntryIdType(MapiDistributionListEntryIdType.Contact);
    member2.setEntryId(Base64.getDecoder().decode(strEntryId2));

    MapiDistributionListMemberCollection members = new MapiDistributionListMemberCollection();
    members.add(member1);
    members.add(member2);

    MapiDistributionList distributionList = new MapiDistributionList("Contact list", members);
    distributionList.setBody("Distribution List Body");
    distributionList.setSubject("Sample Distribution List using Aspose.Email");

    // Add distribution list to PST
    contactFolder.addMapiMessageItem(distributionList);
}

// Create one-off distribution list members (for which no separate contacts were created)
try (PersonalStorage personalStorage = PersonalStorage.create(dataDir + "CreateDistributionListInPST_OneOffmembers_out.pst", FileFormatVersion.Unicode)) {
    // Add the contact folder to pst
    FolderInfo contactFolder = personalStorage.createPredefinedFolder("Contacts", StandardIpmFolder.Contacts);

    MapiDistributionListMemberCollection oneOffmembers = new MapiDistributionListMemberCollection();
    oneOffmembers.add(new MapiDistributionListMember("John R. Patrick", "[e-mail]"));
    oneOffmembers.add(new MapiDistributionListMember("Tilly Bates", "[e-mail]"));

    MapiDistributionList oneOffMembersList = new MapiDistributionList("Simple list", oneOffmembers);
    contactFolder.addMapiMessageItem(oneOffMembersList);
}

将 Mapi 通讯组列表保存为单个多联系人 VCF 文件

该 void save(String fileName, MapiDistributionListSaveOptions options) 此方法允许使用提供的保存选项将 Mapi 通讯组列表保存到指定的文件名。您可以提供文件名和该类的实例 MapiDistributionListSaveOptions 类作为参数。该 MapiDistributionListSaveOptions 此类包含保存 Mapi 通讯组列表的选项。在这种情况下，您可以将保存格式指定为 VCard（ContactSaveFormat.VCard），以将通讯组列表保存为多联系人 VCF 文件。

以下代码片段演示了如何将通讯组列表保存为多联系人 VCF 文件：

MapiDistributionList dlist = (MapiDistributionList)msg.toMapiMessageItem();
MapiDistributionListSaveOptions options = new MapiDistributionListSaveOptions(ContactSaveFormat.VCard);
dlist.save("distribution_list.vcf", options);

从 PST 读取通讯组列表

以下代码片段展示了如何从 PST 文件读取通讯组列表。

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-Java
// The path to the File directory.
String fileName = "outlook/message.msg";

MapiMessage message = MapiMessage.fromFile(fileName);
MapiDistributionList dlist = (MapiDistributionList)message.toMapiMessageItem();
