问题描述

有几个问题与堆栈溢出类似，但不完全相同.

我想在 win xp 计算机上打开或创建一个本地组并向其中添加成员、域、本地和知名帐户.我还想检查一个用户是否已经是会员，这样我就不会两次添加相同的帐户，并且可能会出现异常.

到目前为止，我开始将 DirectoryEntry 对象与 WinNT:// 提供程序一起使用.一切正常，但我一直在纠结如何获取群组成员列表?

有人知道怎么做吗?或者提供比使用 DirectoryEntry 更好的解决方案?

好的，花了一段时间，尝试了不同的解决方案，但下面给出了最适合我最初问题的解决方案.我无法使用标准"方法让 DirectoryEntry 对象访问本地组的成员，我可以让它枚举成员的唯一方法是使用 Invoke 方法调用本机对象的成员方法.<前>using(DirectoryEntry groupEntry = new DirectoryEntry("WinNT://./Administrators,group")){foreach((IEnumerable) groupEntry.Invoke("Members") 中的对象成员){using(DirectoryEntry memberEntry = new DirectoryEntry(member)){Console.WriteLine(memberEntry.Path);}}}

我还使用了类似的技术在本地组中添加和删除成员.

希望这对其他人也有帮助.基思.

EDIT by Tim:添加了 VB.Net 版本

公共函数MembersOfGroup(ByVal GroupName As String) As List(Of DirectoryEntry)Dim 成员作为新列表(Of DirectoryEntry)尝试使用搜索作为新的 DirectoryEntry("WinNT://./" & GroupName & ",group")For Each member As Object In DirectCast(search.Invoke("Members"), IEnumerable)Dim memberEntry 作为新的 DirectoryEntry(成员)members.Add(memberEntry)下一个结束使用Catch ex 作为例外MessageBox.Show(ex.ToString)结束尝试回归会员结束函数

There are a couple of questions similar to this on stack overflow but not quite the same.

I want to open, or create, a local group on a win xp computer and add members to it, domain, local and well known accounts. I also want to check whether a user is already a member so that I don't add the same account twice, and presumably get an exception.

So far I started using the DirectoryEntry object with the WinNT:// provider. This is going ok but I'm stuck on how to get a list of members of a group?

Anyone know how to do this? Or provide a better solution than using DirectoryEntry?

Okay, it's taken a while, messing around with different solutions but the one that fits best with my original question is given below. I can't get the DirectoryEntry object to access the members of a local group using the 'standard' methods, the only way I could get it to enumerate the members was by using the Invoke method to call the native objects Members method.

using(DirectoryEntry groupEntry = new DirectoryEntry("WinNT://./Administrators,group"))
{
    foreach(object member in (IEnumerable) groupEntry.Invoke("Members"))
    {
        using(DirectoryEntry memberEntry = new DirectoryEntry(member))
        {
            Console.WriteLine(memberEntry.Path);
        }
    }
}

I also used a similar technique to add and remove members from the local group.

Hopefully this helps someone else as well. Keith.

EDIT by Tim: added VB.Net version

Public Function MembersOfGroup(ByVal GroupName As String) As List(Of DirectoryEntry)
    Dim members As New List(Of DirectoryEntry)
    Try
        Using search As New DirectoryEntry("WinNT://./" & GroupName & ",group")
            For Each member As Object In DirectCast(search.Invoke("Members"), IEnumerable)
                Dim memberEntry As New DirectoryEntry(member)
                members.Add(memberEntry)
            Next
        End Using
    Catch ex As Exception
        MessageBox.Show(ex.ToString)
    End Try
    Return members
End Function
