Question

我一直在寻找解决方案，但我找到的所有解决方案都很慢。我想让本地Windows组中的所有用户。该组当然也可以包含AD组。因此，结果应包含作为组成员的所有用户和包含的AD组的用户。你知道一个具有良好性能的解决方案吗？

您是否尝试过此示例，此示例将获取本地计算机中的管理员组成员

using System;
using System.DirectoryServices.AccountManagement;
using System.Collections;

class Program
{
    static void Main(string[] args)
    {
        ArrayList myGroups = GetGroupMembers("Administrators");
        foreach (string item in myGroups)
        {
            Console.WriteLine(item);
        }
        Console.ReadLine();
    }

    public static ArrayList GetGroupMembers(string sGroupName)
    {
        ArrayList myItems = new ArrayList();
        GroupPrincipal oGroupPrincipal = GetGroup(sGroupName);

        PrincipalSearchResult<Principal> oPrincipalSearchResult = oGroupPrincipal.GetMembers();

        foreach (Principal oResult in oPrincipalSearchResult)
        {
            myItems.Add(oResult.Name);
        }
        return myItems;
    }

    public static GroupPrincipal GetGroup(string sGroupName)
    {
        PrincipalContext oPrincipalContext = GetPrincipalContext();

        GroupPrincipal oGroupPrincipal = GroupPrincipal.FindByIdentity(oPrincipalContext, sGroupName);
        return oGroupPrincipal;
    }

    public static PrincipalContext GetPrincipalContext()
    {
        PrincipalContext oPrincipalContext = new PrincipalContext(ContextType.Machine);
        return oPrincipalContext;
    }

}

嘿，我做了一组类来做这个，但是它是基于Domain而不是group：）

这是课程。有一个userManager类和一个User类

public class UserManager
{
    private string _domainName;
    private Dictionary<string, User> _userLookup;
    private PrincipalContext domainContext;
    private DirectoryEntry LDAPdirectory;

    public UserManager(string domainName)
    {
        _domainName = domainName;
        _userLookup = new Dictionary<string, User>();
        domainContext = new PrincipalContext(ContextType.Domain, _domainName);
        //Make the LDAP directory look for all users within the domain. DC Com, Au for australia
        LDAPdirectory = new DirectoryEntry("LDAP://DC=" + _domainName.ToLower() + ",DC=com,DC=au");
        LDAPdirectory.AuthenticationType = AuthenticationTypes.Secure;
    }


    public IEnumerable<User> Users
    {
        get
        {
            return _userLookup.Values.ToArray<User>();
        }
        set
        {
            _userLookup.Clear();
            foreach (var user in value)
            {
                if (!_userLookup.ContainsKey(user.Login))
                    _userLookup.Add(user.Login, user);
            }
        }
    }

    /// <summary>
    /// Gets all the users from the AD domain and adds them to the Users property. Returns the list.
    /// </summary>
    /// <returns></returns>
    public IEnumerable<User> UpdateAllUsers()
    {

        DirectorySearcher searcher = new DirectorySearcher(LDAPdirectory);
        searcher.Filter = "(&(&(objectClass=user)(objectClass=person)(!objectClass=computer)(objectClass=organizationalPerson)(memberof=*)(telephonenumber=*)))";

        SearchResultCollection src = searcher.FindAll();
        _userLookup.Clear();

        foreach (SearchResult result in src)
        {
            User newUser = new User(domainContext, result.Properties["samaccountname"][0].ToString());

            if (newUser.IsInitialized)
            {
                _userLookup.Add(newUser.Login, newUser);
                yield return newUser;
            }
        }



    }
    public User GetUser(string userLogin)
    {
        return new User(domainContext, userLogin);
    }

    public bool HasUser(string login)
    {
        return _userLookup.ContainsKey(login);
    }
}

public class User
{
    public User()
    {
        IsInitialized = false;
    }
    /// <summary>
    /// Initializes a new user based on the AD info stored in the domain    
    /// </summary>
    /// <param name="domainContext">The domain to search for this user</param>
    /// <param name="userName">The user to look for</param>
    public User(PrincipalContext domainContext, string userName)
    {
        try
        {
            using (UserPrincipal thisUserPrincipal = UserPrincipal.FindByIdentity(domainContext, userName))
            {
                this.FirstName = thisUserPrincipal.GivenName;
                this.Surname = thisUserPrincipal.Surname;
                this.DisplayName = thisUserPrincipal.DisplayName;
                this.Email = thisUserPrincipal.EmailAddress;
                this.ContactNumber = thisUserPrincipal.VoiceTelephoneNumber;
                this.Login = thisUserPrincipal.SamAccountName;
                IsInitialized = true;
            }
        }
        catch (Exception)
        {
            IsInitialized = false;
            return;
        }
    }
    /// <summary>
    /// Gets a value determining if this user was properly initialized or if an exception was thrown during creation
    /// </summary>
    public bool IsInitialized { get; set; }
    public string FirstName { get; set; }
    public string Surname { get; set; }
    public string DisplayName { get; set; }
    public string Email { get; set; }
    public string Login { get; set; }
    public string ContactNumber { get; set; }
}

您可以使用powershell来解决此问题。

function GetLocalArray{
    [CmdletBinding()]
    param(
         Parameter(ValueFromPipeline=$True,position=0,mandatory=$true)]$ComputerArray
    )
    BEGIN{
       $members=@()
       $filter=@()
    }
 PROCESS{
    foreach($computer in $ComputerArray){
        $gwmiquery = Get-WMIObject win32_group -filter "LocalAccount='True'" -computername $computer #| where{$_.Name -like "*Administrators"} #uncomment to filter the result to just local administrators group
        $gwmiquery | foreach{ 
                $name=$_.Name; 
                $A=$_.GetRelated("Win32_UserAccount").Name -join ";"; #users
                $B=$_.GetRelated("Win32_Account").Name -join ";";    #systemgroup
                $memberUsers =   New-Object PSObject -Property  @{ComputerName=$_.PSComputerName;Name=$name;AllMembers=$B;Members=$A}
                $members+=$memberUsers;
            }
    }
         $filter+= $members | foreach{$name=$_.name; if( ! [String]::IsNullOrWhiteSpace($_.AllMembers)) { $_ }     }
    }
END{
    return $filter
   }
}

从以下文件中读取计算机：

$computers = Get-Content  $Global:ComputersFile
$AllComputerMembers = GetLocalArray -ComputerArray $computers

从这里你可以使用，convertto-csv，export-csv，convertto-json 在网络或Excel上使用它。
