C# 如何从Active Directory获取组织单位列表?

List source=new List();
DirectoryEntry root=new DirectoryEntry(“LDAP://app.shgbit.com”);
DirectoryEntry gbvision=root.Children.Find(“OU=UMP”);
DirectorySearcher search=新的DirectorySearcher(gbvision);
searcher.Filter=“(objectClass=computer)”;
int指数=1;
foreach(searcher.FindAll()中的每个SearchResult)

您需要使用System.DirectoryServices
中合适的DirectorySearcher
,并且需要搜索organizationalUnit
广告类(我建议基于objectCategory
进行搜索,它是单值和索引的,比使用objectClass
快得多)-类似这样:
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 orgUnits=new List();
DirectoryEntry startingPoint=new DirectoryEntry(“LDAP://DC=YourCompany,DC=com”);
DirectorySearcher search=新的DirectorySearcher(起始点);
searcher.Filter=“(objectCategory=organizationalUnit)”;
foreach(searcher.FindAll()中的SearchResult res)
{
orgUnits.Add(res.Path);
}
我知道这个帖子有点老了,但我最近创建了一种比DirectorySearcher提供的更有效的方法来处理DirectoryEntries,并希望与大家分享,因为这是Google上的最佳结果。此示例基于最初指定的起点复制OU结构
传递给第一个构造函数的DN路径的格式应为“LDAP://OU=StartingOU,DC=test,DC=com”
这是我的解决方案,它正在发挥作用:
List<string> DisplayedOU = new List<string>();

杰米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。我正在使用此代码填充树视图,其中显示我的广告环境中的OU:
