如何获得本地组中的所有用户（具有良好性能）

Question

我在寻找解决方案的时间相当长，但我发现所有解决方案都非常慢。 我想让本地窗口组中的所有用户。该组当然也可以含有AD组。因此，结果应包含属于该组本身的成员的所有用户和所包含的AD组的用户。 您是否知道一个具有良好性能的解决方案？

Answer 1

您是否尝试过这个，这个样本获取管理员组的成员在本地计算机

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，我做了一组类来做到这一点而回，但它得到了他们基于域而不是组:) :)

这里是类。有一个userManager类和一个用户类

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; } 
}

你可以使用powershell来解决这个问题。

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 
    } 
} 

阅读计算机免受这样的文件：

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

从这里也可以使用，的ConvertTo-CSV，出口CSV，的ConvertTo-JSON 把它用在网页或Excel。
