Question

有人能告诉我从Exchange Server获取联系人列表的最简单方法吗？我正在使用C＃

根据我的发现， Exchange Web服务仅适用于Exchange Server 2007及更高版本。这将是我的第一个选择，但我也想要替代以前版本的Exchange（WebDav或其他东西）。目录服务不是一种选择。

这是如何使用EWS从您的联系人列表中获取联系人列表。我不确定如何从全局列表中获取联系人，仅在一小时前查看了API。

private static void ListContacts(ExchangeService svc) {
    foreach (var v in svc.FindItems(WellKnownFolderName.Contacts,
                                    new ItemView(20))) {
        Contact contact = v as Contact;
        ContactGroup contactGroup = v as ContactGroup;

        //v.Load(); // Turns out you don't need to load for basic props.
        if (contact != null) {
            Console.WriteLine("Contact: {0} <{1}>",
                contact.DisplayName,
                contact.EmailAddresses[EmailAddressKey.EmailAddress1]);
        } else if (contactGroup != null) {
            Console.WriteLine("Contact Group: {0}", contactGroup.DisplayName);
            switch (svc.RequestedServerVersion) {
                case ExchangeVersion.Exchange2007_SP1:
                    ExpandGroupResults groupResults
                        = svc.ExpandGroup((contactGroup.Id));
                    foreach (var member in groupResults) {
                        Console.WriteLine("+ {0} <{1}>",
                            member.Name, member.Address);
                    }
                    break;
                case ExchangeVersion.Exchange2010:
                    foreach (GroupMember member in contactGroup.Members) {
                        Console.WriteLine("+ {0} <{1}>",
                        member.AddressInformation.Name,
                        member.AddressInformation.Address);
                    }
                    break;
                default:
                    Console.WriteLine(
                        "** Unknown Server Version: {0}",
                        svc.RequestedServerVersion);
                    break;
            }
        } else {
            Console.WriteLine("Unknown contact type: {0} - {1}",
                contact.GetType(), v.Subject);
        }
    }
}

我已经无视创建动词服务，请查看Exchange Web Services API以获取更多信息。

首先，不要忘记添加对Microsoft Exchange Web服务库的引用。

private static void ConnectToExchangeService()
{
    service = new ExchangeService(); 
    service.Credentials = new WebCredentials(USERNAME, PASSWORD, DOMAIN_NAME);
    service.AutodiscoverUrl(USER_ADDRESS);
}

private static void ListGlobalContacts(ExchangeService service)
{
    /* passing true as the third parameter to "ResolveName" is important to
       make sure you get the contact details as well as the mailbox details */
    NameResolutionCollection searchResult = service.ResolveName(NAME_YOURE_LOOKING_FOR, ResolveNameSearchLocation.DirectoryOnly, true);
    foreach (NameResolution resolution in searchResult )
    {
        Console.WriteLine("name is " + resolution.Contact.DisplayName);
        Console.WriteLine("address is " + resolution.Mailbox.Address);
        Console.WriteLine("business phone is " + resolution.Contact.PhoneNumbers[PhoneNumberKey.BusinessPhone]);
        Console.WriteLine("mobile phone is " + resolution.Contact.PhoneNumbers[PhoneNumberKey.MobilePhone]);
    }
}

...而且Brett Ryan已经提供了获取本地联系人列表的代码。

这种检索全局联系人列表的方法（好吧，至少其中一个）的问题是，“ResolveName”函数最多可以返回100个联系人，这样如果你的组织有更多的记录，你就在麻烦。一种可能的解决方法（以及我实现的解决方法）是对每个字母进行单独搜索（假设您可以验证此类搜索将始终返回少于100个结果）并将所有唯一条目串在一起列为一个列表。
