读取/筛选活动目录的通讯组的子组？

Question

我有一个Active Directory域与myDomain.local ，其下存在一个Distribution Group包含多个组。
如何阅读（以编程方式）所有这些子组以检索其名称列表？
以及如何优化查询以过滤结果，使其仅检索以单词Region结尾的所有组？
顺便说一句，我正在使用C＃.Net，ASP.Net和sharepoint，而我对AD没有任何经验。

如果您使用的是.NET 3.5（或可以升级到它），则可以使用System.DirectoryServices.AccountManagement命名空间使用以下代码：

// create the "context" in which to operate - your domain here, 
// as the old-style NetBIOS domain, and the container where to operate in
PrincipalContext ctx = new PrincipalContext(ContextType.Domain, "YOURDOMAIN", "cn=Distribution Group,dc=YourDomain,dc=local");

// define a "prototype" - an example of what you're searching for
// Here: just a simple GroupPrincipal - you want all groups
GroupPrincipal prototype = new GroupPrincipal(ctx);

// define a PrincipalSearcher to find those principals that match your prototype
PrincipalSearcher searcher = new PrincipalSearcher(prototype);

// define a list of strings to hold the group names        
List<string> groupNames = new List<string>();

// iterate over the result of the .FindAll() call
foreach(var gp in searcher.FindAll())
{
    // cast result to GroupPrincipal
    GroupPrincipal group = gp as GroupPrincipal;

    // if everything - grab the group's name and put it into the list
    if(group != null)
    {
       groupNames.Add(group.Name);
    }
}

满足您的需求吗？

这是我提出的解决方案； 对于那些感兴趣的人：

public ArrayList getGroups()
{
    // ACTIVE DIRECTORY AUTHENTICATION DATA
    string ADDomain = "myDomain.local";
    string ADBranchsOU = "Distribution Group";
    string ADUser = "Admin";
    string ADPassword = "password";

    // CREATE ACTIVE DIRECTORY ENTRY 
    DirectoryEntry ADRoot 
        = new DirectoryEntry("LDAP://OU=" + ADBranchsOU
                             + "," + getADDomainDCs(ADDomain),
                             ADUser, 
                             ADPassword);

    // CREATE ACTIVE DIRECTORY SEARCHER
    DirectorySearcher searcher = new DirectorySearcher(ADRoot);
    searcher.Filter = "(&(objectClass=group)(cn=* Region))";
    SearchResultCollection searchResults = searcher.FindAll();

    // ADDING ACTIVE DIRECTORY GROUPS TO LIST
    ArrayList list = new ArrayList();
    foreach (SearchResult result in searchResults)
    {
        string groupName = result.GetDirectoryEntry().Name.Trim().Substring(3);
        list.Add(groupName);
    }
    return list; 
}

public string getADDomainDCs(string ADDomain)
{
    return (!String.IsNullOrEmpty(ADDomain)) 
        ? "DC=" + ADDomain.Replace(".", ",DC=") 
        : ADDomain;
}
