c# - 获取本地组而不是域用户的主要组

Question

我有一个代码来获取用户所属的组。

try 
        {
            DirectoryEntry adRoot = new DirectoryEntry(string.Format("WinNT://{0}", Environment.UserDomainName));

            DirectoryEntry user = adRoot.Children.Find(completeUserName, "User");                
            object obGroups = user.Invoke("Groups");
            foreach (object ob in (IEnumerable)obGroups)
            {
                // Create object for each group.
                DirectoryEntry obGpEntry = new DirectoryEntry(ob);
                listOfMyWindowsGroups.Add(obGpEntry.Name);
            }
        return true;
        }
        catch (Exception ex)
        {
            new GUIUtility().LogMessageToFile("Error in getting User MachineGroups = " + ex);
            return false;
        }

当我必须找到本地用户的组时，上面的代码工作正常但是

对于域用户，它返回一个值“域用户”，这有点奇怪，因为它是 2 个本地组的一部分。

请有人帮忙解开这个谜团。谢谢

Research

我做了一些发现并得到我返回域用户的主要组

称为“域用户”组

但我真正想要的是域用户所属的本地计算机组......我无法得到......任何建议

another code using LDAP

        string domain = Environment.UserDomainName;
        DirectoryEntry DE = new DirectoryEntry("LDAP://" + domain, null, null, AuthenticationTypes.Secure);
        DirectorySearcher search = new DirectorySearcher();

        search.SearchRoot = DE;         
        search.Filter = "(SAMAccountName=" + completeUserName + ")";  //Searches active directory for the login name

        search.PropertiesToLoad.Add("displayName");  // Once found, get a list of Groups

        try
        {
            SearchResult result = search.FindOne(); // Grab the records and assign them to result
            if (result != null)
            {
                DirectoryEntry theUser = result.GetDirectoryEntry();
                theUser.RefreshCache(new string[] { "tokenGroups" });
                foreach (byte[] resultBytes in theUser.Properties["tokenGroups"])
                {
                    System.Security.Principal.SecurityIdentifier mySID = new System.Security.Principal.SecurityIdentifier(resultBytes, 0);

                    DirectorySearcher sidSearcher = new DirectorySearcher();

                    sidSearcher.SearchRoot = DE;
                    sidSearcher.Filter = "(objectSid=" + mySID.Value + ")";
                    sidSearcher.PropertiesToLoad.Add("distinguishedName");

                    SearchResult sidResult = sidSearcher.FindOne();

                    if (sidResult != null)
                    {
                        listOfMyWindowsGroups.Add((string)sidResult.Properties["distinguishedName"][0]);
                    }
                }
            }
            else
            {
                new GUIUtility().LogMessageToFile("no user found");

            }
            return true;
        }

        catch (Exception ex)
        {

            new GUIUtility().LogMessageToFile("Error obtaining group names: " + ex.Message + " Please contact your administrator."); // If an error occurs report it to the user.
            return false;
        }

这也有效，但我得到相同的结果“域用户”。请有人告诉我如何获得本地机器组...？？？？

如果您使用的是 .NET 3.5，则可以使用 System.DirectoryService.AccountManagement做所有的用户和组管理。特别是，UserPrincipal.GetAuthorizationGroups正是您要寻找的。它为特定用户检索本地​​组和机器组。如果该组是本地组，则 GroupPrincipal.Context.Name 显示该组所在的计算机名称。如果该组是域组，则 GroupPrincipal.Context.Domain 显示该组来自的域名。

PrincipalContext context = new PrincipalContext(ContextType.Domain, "yourdomain.com");
UserPrincipal userPrincipal = UserPrincipal.FindByIdentity(context, IdentityType.SamAccountName, "youruser"); 

foreach (GroupPrincipal group in userPrincipal.GetAuthorizationGroups())
{
    Console.Out.WriteLine("{0}\\{1}", group.Context.Name, group.SamAccountName);
}
