使用 C# 获取 Active Directory 用户数据

我想获取有关特定用户的数据。我知道该用户的 OU 路径，但无法使用该 OU 路径获取信息。总是说找不到用户。谁能告诉我我需要更改搜索过滤器吗？请帮忙 。

Code

用户路径 abc.ds.xyz.net/fGroup/xcxc/Users/123456 abc.ds.xyz.net 是域，然后 fGroup 是 OU ，xcxc 是 OU ，用户是 OU ，123456 是 cn 。

    namespace Ldap_authentication
    {
       public class Program
       {
         static void Main(string[] args)
         {

            Console.Write("Enter user: ");
            String username = Console.ReadLine();

            try
            {
              DirectoryEntry myLdapConnection = createDirectoryEntry();

              DirectorySearcher search = new DirectorySearcher(myLdapConnection);
              search.Filter = "(&(OU=fGroup)(OU=xcxc )(OU=Users)(cn=" + username + "))";
              SearchResult result = search.FindOne();

              if (result != null)
              {

                ResultPropertyCollection fields = result.Properties;

                foreach (String ldapField in fields.PropertyNames)
                {

                    foreach (Object myCollection in fields[ldapField])
                        Console.WriteLine(String.Format("{0,-20} : {1}",
                                      ldapField, myCollection.ToString  ()));
                }
             }

             else
             {
                // user does not exist  
                Console.WriteLine("User not found!");
                Console.ReadLine();
             }
         }

        catch (Exception e)
        {
            Console.WriteLine("Exception caught:\n\n" + e.ToString());
             Console.ReadLine();
        }


    }
    static DirectoryEntry createDirectoryEntry()
    {
        DirectoryEntry ldapConnection = new DirectoryEntry("abc.ds.xyz.net");
        ldapConnection.Path = "LDAP://DC=abc,DC=ds,DC=xyz,DC=net";
        ldapConnection.AuthenticationType = AuthenticationTypes.Secure;
        return ldapConnection;
    }
   }
  }

EDIT

    search.Filter = "(&(OU=fGroup))";
    SearchResult result = search.FindOne();

当我更改 search.Filter = "(&(OU=fGroup)(OU=xcxc )(OU=Users)(cn=" + username + "))";进入 search.Filter = "(&(OU=fGroup))";我得到结果了。谁能告诉我如何使用多个搜索输入过滤器进行搜索。

在我的头撞在墙上几个小时后，我终于找到了答案。我需要编写多个搜索过滤器，例如

旧代码 search.Filter = "(&(OU=fGroup))";用这个替换这个

   search.Filter = "(&(OU=fGroup))";
   search.Filter = "(&(OU=xcxc))";
   search.Filter = "(&(OU=Users))";
   search.Filter = "(&(cn=" + username + "))";
   SearchResult result = search.FindOne();

   Finally found my answer :) . Happy Coding guys :)
