在活动目录中查找组大小

发布于 2024-09-04 05:18:58 字数 365 浏览 8 评论 0原文

我有以下代码。我得到一个用户的目录条目（strpath）。然后我获取列出用户的组。

如何获取每个组中的用户数量？

DirectoryEntry myDE = new System.DirectoryServices.DirectoryEntry(strpath);
object obGroups = myDE.Invoke("Groups");
foreach (object ob in (IEnumerable)obGroups)
{
    DirectoryEntry obGpEntry = new DirectoryEntry(ob);
    GroupsListBox.Items.Add(obGpEntry.Name );
}

原文

I have the following code. I get a directory entry for a user (strpath).
And then I get the groups where the user is listed.

How can I get the number of users in each group?

DirectoryEntry myDE = new System.DirectoryServices.DirectoryEntry(strpath);
object obGroups = myDE.Invoke("Groups");
foreach (object ob in (IEnumerable)obGroups)
{
    DirectoryEntry obGpEntry = new DirectoryEntry(ob);
    GroupsListBox.Items.Add(obGpEntry.Name );
}

如果您使用的是 .NET 3.5（或可以升级到它），则有一个大规模扩展的 System.DirectoryServices.AccountManagement 命名空间，可以使管理用户、组及其成员资格的工作变得更加容易。

查看 MSDN 文章管理 .NET Framework 3.5 中的目录安全主体有关 S.DS.AM 的介绍。

您可以获得这样的用户主体：

PrincipalContext ctx = new PrincipalContext(ContextType.Domain, "YOURDOMAIN");

UserPrincipal user = UserPrincipal.FindByIdentity("some user name");

PrincipalSearchResult<Principal> userGroups = user.GetGroups();

foreach (Principal p in myGroups)
{
    GroupPrincipal gp = (p as GroupPrincipal);

    if (gp != null)
    {
        int memberCount = gp.Members.Count;
    }
}

这样，您可以枚举给定用户拥有的所有组，并枚举这些组，您可以找出每个组有多少个成员（用户和其他组）。

If you're on .NET 3.5 (or can upgrade to it), there's a massively extended System.DirectoryServices.AccountManagement namespace that makes these jobs of managing user, groups and their memberships a whole lot easier.

Check out the MSDN article Managing Directory Security Principals in the .NET Framework 3.5 for an introduction to S.DS.AM.

You can get a user principal like this:

PrincipalContext ctx = new PrincipalContext(ContextType.Domain, "YOURDOMAIN");

UserPrincipal user = UserPrincipal.FindByIdentity("some user name");

PrincipalSearchResult<Principal> userGroups = user.GetGroups();

foreach (Principal p in myGroups)
{
    GroupPrincipal gp = (p as GroupPrincipal);

    if (gp != null)
    {
        int memberCount = gp.Members.Count;
    }
}

This way, you can enumerate all groups a given user has, and enumerating those groups, you can find out how many members (users and other groups) each group has.
