Using VB.NET, call the "Members" native ADSI method, VB has the advantage of better
late binding support over C#:
Imports System.DirectoryServices
Imports System
Module Module1
Sub Main()
' using late binding
Dim MembersCollection as Object
Try
'Get the entries of the Users group 'Group' collection
Dim Group As new DirectoryEntry ("WinNT://servername/Users,group")
MembersCollection = Group.Invoke("Members")
Dim filter As System.Object() = {"user"}
MembersCollection.Filter = filter
' Iterate over the User objects (IADsUser) using late binding
Dim user as Object
for each user in MembersCollection
Console.WriteLine("ADsPath "+ user.ADsPath + " Name: " + user.Name )
next
Catch ex As Exception
Console.WriteLine(ex.Message)
End Try
End Sub
End Module
' Compile from the command line using:
'vbc /r:system.directoryservices.dll,System.dll groupmembers.vb
Using C#, you have add a reference to the "activeds.tlb" and call the Native ADSI
method "Members".
using activeds;
....
IADsMembers MembersCollection = null;
try {
DirectoryEntry groupEntry = new
DirectoryEntry("WinNT://ServerName/Administrators,Group");
PropertyCollection pcoll = groupEntry.Properties;
MembersCollection = groupEntry.Invoke("Members") as IADsMembers;
object[] filter = {"user"};
MembersCollection.Filter = filter;
// enumerate members of collection object that supports the IADsMembers interface
// ADSI provider doesn't support count property
try {
foreach (IADsUser member in MembersCollection) {
Console.WriteLine("ADsPath "+ member.ADsPath + " Name: " + member.Name );
}
}
catch (COMException e) {
Console.WriteLine("Error: {0}",e.Message);
}
}
catch (COMException e) {
Console.WriteLine(e.Message);
}
....
....
