在C#中枚举林和构建域树的快速方法? [英] Fast way to enumerate forest and build domain trees in C#?
问题描述
我需要在 域中构建一个树森林 的。到目前为止,我使用了以下代码:
I need to build a trees of domains in a forest. So far I have used the following code:
using System.DirectoryServices.ActiveDirectory;
...
List<Domain> domains = new List<Domain>(); // flat list of domains
foreach (Domain dom in Forest.GetCurrentForest().Domains)
{
try
{
domains.Add(dom);
var de = dom.GetDirectoryEntry();
// Here I have de.Guid and de.Parent.Guid, so using them I can build a tree
}
catch () {} // for simplicity left it blank.
}
代码效果很好。但是当某些域变得不可用时,响应( Domain.GetDirectoryEntry() )可能需要一段时间(15-20秒)。但是使用Active Directory域和信任,可以使用问题域快速检索所有林树,所以我想在某处有一些域缓存。
问:
如果此缓存位于全局目录中,我想知道 - 是否可以在没有GC的情况下使用AD结构?
我如何执行更快的森林域枚举,并构建树结构?
The code works well. But when some of the domain becomes unavailable, the response (Domain.GetDirectoryEntry()) can take a while (15-20 sec.) before exception throwing. But using Active Directory Domains and Trusts, it is possible to retrieve all forest trees pretty fast with problem domains, so I suppose that there is some cache of domains somewhere.
Q:
If this cache is in the Global Catalog, I wonder - is it possible to have AD structure without GC?
And how can I perform a faster enumeration of forest domains, and build a tree structure?
