如何使用c＃使用DomainName获取AD中OU名称的列表？ [英] How to get list of OU name in AD using DomainName using c#?

问题描述

我想从Active Directory中获取OU列表。

我只有域名。

解决方案

尝试如下操作：

  //连接到 RootDSE以查找默认命名上下文。
 DirectoryEntry rootDSE = new DirectoryEntry（ LDAP：// RootDSE）; 
 
 string defaultContext = rootDSE.Properties [ defaultNamingContext] [0] .ToString（）; 
 
 //绑定到默认命名上下文-如果*知道*您要绑定的位置-
 //您可以立即使用该信息
 DirectoryEntry domainRoot = new DirectoryEntry（ LDAP：// + defaultContext）; 
 
 //根据默认的命名上下文条目设置目录搜索器
 DirectorySearcher ouSearcher = new DirectorySearcher（domainRoot）; 
 
 // SearchScope：OneLevel =仅直属下属（顶级OU）； 
 //子树=整个域中的所有OU（可能需要**很长的时间！）
 ouSearcher.SearchScope = SearchScope.OneLevel; 
 // ouSearcher.SearchScope = SearchScope.Subtree; 
 
 //定义要加载的属性-在这里，我只是获得 OU属性，即OU的名称。
 ouSearcher.PropertiesToLoad.Add（ ou）; 
 
 //定义过滤器-仅选择组织单位
 ouSearcher.Filter =（objectCategory = organizationalUnit）; 
 
 //执行搜索并遍历结果
 foreach（ouSearcher.FindAll（）中的SearchResult deResult）
 {
字符串ouName = deResult.Properties [ ou ] [0] .ToString（）; 
} 
  

如果您拥有域名（例如， mycompany。 com ），则LDAP根域通常 称为 dc = mycompany，dc = com -这是一个约定，但不一定非要那样。这就是为什么我要连接到 LDAP：// RootDSE 虚拟LDAP根目录并读出属性默认命名上下文这为我提供了默认的LDAP路径。

如果您知道要连接的位置-可以跳过第一步，仅提供有效的LDAP路径（例如 LDAP：// dc = YourCompany，dc = co，dc = jp 或其他）来创建 domainRoot 目录条目。 / p>

i want to get list of OU from Active Directory.

i have only domain name.

how can i achieve this using c#?

解决方案

Try something like this:

// connect to "RootDSE" to find default naming context
DirectoryEntry rootDSE = new DirectoryEntry("LDAP://RootDSE");

string defaultContext = rootDSE.Properties["defaultNamingContext"][0].ToString();

// bind to default naming context - if you *know* where you want to bind to - 
// you can just use that information right away
DirectoryEntry domainRoot = new DirectoryEntry("LDAP://" + defaultContext);

// 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.OneLevel;
// 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)";

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

If you have a domain name (e.g. mycompany.com), then the LDAP root domain typically will be called dc=mycompany,dc=com - that's a convention, it doesn't have to be that way though. That's why I'm connecting to the LDAP://RootDSE virtual LDAP root and I read out the property Default Naming Context which gives me the default LDAP path.

If you know where you want to connect to - feel free to skip that first step and just provide the valid LDAP path (e.g. LDAP://dc=YourCompany,dc=co,dc=jp or whatever) to create the domainRoot directory entry.
