在 AD 组中获取用户的电子邮件

Question

我正在使用此代码获取 AD 中特定组中的用户列表

private DirectoryEntry _directoryEntry = null;

private DirectoryEntry SearchRoot

{

    get

    {

        if (_directoryEntry == null)

        {

            _directoryEntry = new DirectoryEntry(_ldapDomain, _user, PBKDF2Algorithm.Decrypt(_password, "PAssword"), AuthenticationTypes.Secure);

        }

        return _directoryEntry;

    }

}

public List<User> GetUserFromGroup(String groupName)

{

    List<User> userlist = new List<User>();

    try

    {

        DirectorySearcher directorySearch = new DirectorySearcher(SearchRoot)

        {

            Filter = "(&(objectClass=group)(SAMAccountName=" + groupName + "))"

        };

        var results = directorySearch.FindOne();

        if (results != null)

        {

            DirectoryEntry deGroup = new DirectoryEntry(results.Path, _user, PBKDF2Algorithm.Decrypt(_password, "PAssword"));

            PropertyCollection pColl = deGroup.Properties;

            int count = pColl["member"].Count;

            for (int i = 0; i < count; i++)

            {

                string respath = results.Path;

                string[] pathnavigate = respath.Split("CN".ToCharArray());

                respath = pathnavigate[0];

                string objpath = pColl["member"][i].ToString();

                string path = respath + objpath;

                DirectoryEntry user = new DirectoryEntry(path, _user, PBKDF2Algorithm.Decrypt(_password, "!twcActiveDirectory!"));

                User userobj = User.GetUser(user);

                userlist.Add(userobj);

                user.Close();

            }

        }

        return userlist.Where(item => !string.IsNullOrEmpty(item.FirstName) || !string.IsNullOrWhiteSpace(item.FirstName)).ToList();

    }

    catch (Exception ex)

    {

        return userlist;

    }

}

返回的属性不包含用户的电子邮件地址，后来我找到了一种检索用户代理地址的方法，这正是我正在寻找的，但问题是我只成功检索了主根中的用户，而不是为一个特定的群体。

那么，有什么方法可以合并两个代码？

Answer 1

我找到了一种方法，如下所示：为每个组加载用户为每个用户建立登录名使用 PrincipalContext 搜索每个用户的登录名为每个用户加载 ProxyAddresses 和 Mail 属性这是一个解释这个想法的代码：&nbsp; &nbsp; DirectoryEntry _directoryEntry = null;private DirectoryEntry SearchRoot&nbsp;
