Active Directory/C#：使用多个OU获取单个域中的用户？

using System;
using System.DirectoryServices;

class Program
{
    static void Main()
    {
        string domainPath = "LDAP://yourdomain.com";
        string ouPath1 = "OU=OU1,DC=yourdomain,DC=com";
        string ouPath2 = "OU=OU2,DC=yourdomain,DC=com";

        using (DirectoryEntry domainEntry = new DirectoryEntry(domainPath))
        {
            using (DirectorySearcher searcher = new DirectorySearcher(domainEntry))
            {
                searcher.Filter = "(&(objectClass=user)(objectCategory=person))";
                searcher.SearchScope = SearchScope.Subtree;

                searcher.SearchRoot = new DirectoryEntry(domainPath + "/" + ouPath1);
                SearchResultCollection results1 = searcher.FindAll();

                searcher.SearchRoot = new DirectoryEntry(domainPath + "/" + ouPath2);
                SearchResultCollection results2 = searcher.FindAll();

                // 处理结果
                foreach (SearchResult result in results1)
                {
                    // 处理OU1中的用户
                    Console.WriteLine(result.Properties["samaccountname"][0].ToString());
                }

                foreach (SearchResult result in results2)
                {
                    // 处理OU2中的用户
                    Console.WriteLine(result.Properties["samaccountname"][0].ToString());
                }
            }
        }
    }
