如何从Active Directory获取组织单位列表?

标签: c# directoryservices

我查看了DirectoryServices类,它似乎是我需要的,但我似乎无法找到获取组织单位集合所需的类/方法。

你们能提出一些建议吗?

您需要使用来自DirectorySearcher的相应System.DirectoryServices,并且您需要搜索organizationalUnit AD类(我建议您根据objectCategory进行搜索单值和索引 - 比使用objectClass快得多 - 这样的事情:

List<string> orgUnits = new List<string>();

DirectoryEntry startingPoint = new DirectoryEntry("LDAP://DC=YourCompany,DC=com");

DirectorySearcher searcher = new DirectorySearcher(startingPoint);
searcher.Filter = "(objectCategory=organizationalUnit)";

foreach (SearchResult res in searcher.FindAll()) 
{
    orgUnits.Add(res.Path);
}

List<PlayerBO> source = new List<PlayerBO>();

DirectoryEntry root = new DirectoryEntry("LDAP://app.shgbit.com");
DirectoryEntry gbvision = root.Children.Find("OU=UMP");

DirectorySearcher searcher = new DirectorySearcher(gbvision);
searcher.Filter = "(objectClass=computer)";

int index = 1;

foreach (SearchResult each in searcher.FindAll()) 
{
    var box = each.GetDirectoryEntry();
    source.Add(new PlayerBO { Id = index++, Name = box.Properties["name"].Value.ToString(), Description = box.Properties["description"].Value.ToString() });
}

ListViewAD.ItemsSource = new SelectableSource<PlayerBO>(source);

我知道这个帖子有点陈旧,但我最近创建了一种更有效的方法来操纵DirectoryEntries而不是DirectorySearcher提供和想要分享,因为这是谷歌的最佳结果。此示例基于初始指定的起点复制OU结构。

传递给第一个构造函数的DN路径应采用格式&#34; LDAP:// OU = StartingOU,DC = test,DC = com&#34;

using System.DirectoryServices;
using System.Threading.Tasks;

public class ADTree
{
    DirectoryEntry rootOU = null;
    string rootDN = string.Empty;
    List<ADTree> childOUs = new List<ADTree>();

    public DirectoryEntry RootOU
    {
        get { return rootOU; }
        set { rootOU = value; }
    }

    public string RootDN
    {
        get { return rootDN; }
        set { rootDN = value; }
    }

    public List<ADTree> ChildOUs
    {
        get { return childOUs; }
        set { childOUs = value; }
    }

    public ADTree(string dn)
    {
        RootOU = new DirectoryEntry(dn);
        RootDN = dn;
        BuildADTree().Wait();
    }

    public ADTree(DirectoryEntry root)
    {
        RootOU = root;
        RootDN = root.Path;
        BuildADTree().Wait();
    }

    private Task BuildADTree()
    {
        return Task.Factory.StartNew(() =>
        {
            object locker = new object();
            Parallel.ForEach(RootOU.Children.Cast<DirectoryEntry>().AsEnumerable(), child =>
            {
                if (child.SchemaClassname.Equals("organizationalUnit"))
                {
                    ADTree ChildTree = new ADTree(child);
                    lock (locker)
                    {
                        ChildOUs.Add(ChildTree);
                    }
                }
            });
        });
    }
}

要构建,您需要做的就是:

ADTree Root = null;

Task BuildOUStructure = Task.Factory.StartNew(() =>
{
    ADTree = new ADTree("LDAP://ou=test,dc=lab,dc=net");
});

BuildOUStructure.Wait();

Jamie提供的代码运行良好。为了回答MacGuyver的问题,为了使用Cast扩展,您需要在代码中包含对System.Linq的引用。我正在使用以下代码填充显示AD环境中OU的TreeView:

using System;
using System.Data;
using System.Linq;
using System.Windows.Forms;
using System.Threading.Tasks;
using System.DirectoryServices;
using System.Collections.Generic;
using System.DirectoryServices.ActiveDirectory;

namespace WindowsFormsApp8
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            treeView1.Nodes.Clear();
            string top = string.Format("LDAP://DC={0}", Domain.GetCurrentDomain().Name.Replace(".", ",DC="));
            ADTree tree = null;

            Task BuildOUStructure = Task.Factory.StartNew(() =>
            {
                tree = new ADTree(top);
            });

            BuildOUStructure.Wait();
            foreach(ADTree t in tree.ChildOUs)
            {
                TreeNode node = new TreeNode(t.RootOU.Path);
                treeView1.Nodes.Add(node);
                if(t.ChildOUs.Count > 0)
                {
                    AddChildren(node, t);
                }
            }
        }

        private void AddChildren(TreeNode parent, ADTree tree)
        {
            foreach(ADTree t in tree.ChildOUs)
            {
                TreeNode node = new TreeNode(t.RootOU.Path);
                parent.Nodes.Add(node);
                if(t.ChildOUs.Count > 0)
                {
                    AddChildren(node, t);
                }
            }
        }
    }

    public class ADTree
    {
        DirectoryEntry rootOU = null;
        string rootDN = string.Empty;
        List<ADTree> childOUs = new List<ADTree>();

        public DirectoryEntry RootOU
        {
            get { return rootOU; }
            set { rootOU = value; }
        }

        public string RootDN
        {
            get { return rootDN; }
            set { rootDN = value; }
        }

        public List<ADTree> ChildOUs
        {
            get { return childOUs; }
            set { childOUs = value; }
        }

        public ADTree(string dn)
        {
            RootOU = new DirectoryEntry(dn);
            RootDN = dn;
            BuildADTree().Wait();
        }

        public ADTree(DirectoryEntry root)
        {
            RootOU = root;
            RootDN = root.Path;
            BuildADTree().Wait();
        }

        private Task BuildADTree()
        {
            return Task.Factory.StartNew(() =>
            {
                object locker = new object();
                Parallel.ForEach(RootOU.Children.Cast<DirectoryEntry>().AsEnumerable(), child =>
                {
                    if (child.SchemaClassName.Equals("organizationalUnit"))
                    {
                        ADTree ChildTree = new ADTree(child);
                        lock (locker)
                        {
                            ChildOUs.Add(ChildTree);
                        }
                    }
                });
            });
        }
    }
}

这是在一个简单的Windows窗体应用程序上,该应用程序具有TreeView(treeview1)和Button(button1)-希望对您有所帮助!

您是否查看了DirectorySearcher方法?

以下是MSDNbytes.com的一些示例。

这是我的解决方案,它正在运作:

List<string> DisplayedOU = new List<string>();
int step = 0;
string span = "<span style='margin-left:6px;'> -- </span>";

private void getOU2()
{
    string strRet = "";
    DirectoryEntry domainRoot = new DirectoryEntry("LDAP://uch.ac/OU=ALL,DC=uch,DC=ac", "user", "pass");

    // set up directory searcher based on default naming context entry
    DirectorySearcher ouSearcher = new DirectorySearcher(domainRoot);

    // SearchScope: OneLevel = only immediate subordinates (top-level OUs); 
    // subtree = all OU's in the whole domain (can take **LONG** time!)
    ouSearcher.SearchScope = SearchScope.Subtree;
    // ouSearcher.SearchScope = SearchScope.Subtree;

    // define properties to load - here I just get the "OU" attribute, the name of the OU
    ouSearcher.PropertiesToLoad.Add("ou");

    // define filter - only select organizational units
    ouSearcher.Filter = "(objectCategory=organizationalUnit)";

    int cnt = 0;


    foreach (SearchResult deResult in ouSearcher.FindAll())
    {
        string temp = deResult.Properties["ou"][0].ToString();

        strRet += FindSubOU(deResult.Properties["adspath"][0].ToString(), cnt);

    }

    Literal1.Text = strRet;
}


private string FindSubOU(string OU_Path, int cnt)
{
    string strRet = "";

    DirectoryEntry domainRoot = new DirectoryEntry(OU_Path, "user", "pass");

    // set up directory searcher based on default naming context entry
    DirectorySearcher ouSearcher = new DirectorySearcher(domainRoot);

    // SearchScope: OneLevel = only immediate subordinates (top-level OUs); 
    // subtree = all OU's in the whole domain (can take **LONG** time!)
    ouSearcher.SearchScope = SearchScope.Subtree;
    // ouSearcher.SearchScope = SearchScope.Subtree;

    // define properties to load - here I just get the "OU" attribute, the name of the OU
    ouSearcher.PropertiesToLoad.Add("ou");

    // define filter - only select organizational units
    ouSearcher.Filter = "(objectCategory=organizationalUnit)";

    //adspath
    // do search and iterate over results
    foreach (SearchResult deResult in ouSearcher.FindAll())
    {
        string temp = deResult.Properties["ou"][0].ToString();

        if (!DisplayedOU.Contains(deResult.Properties["ou"][0].ToString()))
        {
            string strPerfix = "";

            for (int i = 0; i < step; i++)
                strPerfix += span;

            strRet += strPerfix + ++cnt + ". " + deResult.Properties["ou"][0].ToString() + " ----> " + deResult.Properties["adspath"][0].ToString() + "<br />";

            DisplayedOU.Add(deResult.Properties["ou"][0].ToString());

            step++;

            strRet += FindSubOU(deResult.Properties["adspath"][0].ToString(), cnt);

            step--;
        }

    }


    return strRet;
}
