How to enumerate open files using DirectoryServices

I am looking for a way to convert the following vbs script to c#

Const ADS_SECURE_AUTHENTICATION = 1
strADMIN = "adminaccount"
strPASSWORD = "password"
strUSER = "useraccount"
Set dso = GetObject("WinNT:")
Set srv = DSO.OpenDSObject("WinNT://servername/LanmanServer", strADMIN,
strPASSWORD, ADS_SECURE_AUTHENTICATION)
Set colResources = srv.Resources
For Each objResource in colResources
If objResource.User = strUSER Then objResource.remove(objResource.Name)
Next


I have seen various c# code using DirectoryServices with the winnt:
provider to enumerate users, groups, shares, etc
But I cant seem to find out how to gather open file or session information.
I know that he below code would show me shares on a file server,
but how do I get it to show me open files and sessions ?

using System;
using System.DirectoryServices;

namespace NetAcademia.Samples
{
class App
{
static void Main()
{
DirectoryEntry root = new DirectoryEntry
("WinNT://servername/lanmanserver");

foreach(DirectoryEntry child in root.Children)
{
Console.WriteLine(child.Name);
}
}
}
}

Thanks for any insight or help with this problem

Hi,

I am not familar with .Net DirectoryServices [coming from scripting, feel
it's a nightmare]. In script, the analogy could possibly help you, it is as
follows:

Set objFSOps = GetObject("WinNT://<box>/lanmanserver")

For Each objSession In objFSOps.Sessions
WScript.Echo objSession.Name
Next

For Each objResource In objFSOps.Resources
WScript.Echo objResource.Name
Next

May be, that helps.

Best regards,
Manfred Braun

Something like this should do the job...
Note that you need to add a reference to the activeds.tlb !!!!!

using (DirectoryEntry container = new
DirectoryEntry("WinNT://servername/LanmanServer")
{
IADsFileServiceOperations fso= container.NativeObject as
IADsFileServiceOperations;
if (fso != null)
{
foreach(IADsSession sess in fso.Sessions()) {
Console.WriteLine("Name : {0} \tUser: {1} \tComputer : {2}",
sess.Name, sess.User, sess.Computer);
}

IADsCollection resources = fso.Resources() as IADsCollection;
Console.WriteLine("----- Resource info -------");
foreach(IADsResource resource in resources)
{
try
{
Console.WriteLine("\tPath: {0}\tUser: {1}\tLockCount: {2}\tName:
{3}",
resource.Path, resource.User, resource.LockCount,
resource.Name);
}
catch (System.IO.FileNotFoundException ex){
// Watch Non-Fileshare resources like named pipes, these are not
stored in the ADSI cache
}
}
}
}

Thank you Willy for the great solution

I would have used WMI but on of our file servers is a NAS device
which doesnt support WMI calls

Now all I need to do is make it remove the session and resources for a
given username,
I assume that Ill be able to call Remove() on the sessions and resources

Thanks

Ok to remove a session...

fso.Sessions().Remove(sess.Name);

Unfortunately, removing a Resource isn't implemented by the provider :-(.
