How to enumerate open files using DirectoryServic es

[Rich Crusco via DotNetMonster.com]

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

Const ADS_SECURE_AUTH ENTICATION = 1
strADMIN = "adminaccou nt"
strPASSWORD = "password"
strUSER = "useraccoun t"
Set dso = GetObject("WinN T:")
Set srv = DSO.OpenDSObjec t("WinNT://servername/LanmanServer", strADMIN,
strPASSWORD, ADS_SECURE_AUTH ENTICATION)
Set colResources = srv.Resources
For Each objResource in colResources
If objResource.Use r = strUSER Then objResource.rem ove(objResource .Name)
Next
I have seen various c# code using DirectoryServic es 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.Director yServices;

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

foreach(Directo ryEntry child in root.Children)
{
Console.WriteLi ne(child.Name);
}
}
}
}

Thanks for any insight or help with this problem

Hi,

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

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

For Each objSession In objFSOps.Sessio ns
WScript.Echo objSession.Name
Next

For Each objResource In objFSOps.Resour ces
WScript.Echo objResource.Nam e
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")
{
IADsFileService Operations fso= container.Nativ eObject as
IADsFileService Operations;
if (fso != null)
{
foreach(IADsSes sion sess in fso.Sessions()) {
Console.WriteLi ne("Name : {0} \tUser: {1} \tComputer : {2}",
sess.Name, sess.User, sess.Computer);
}

IADsCollection resources = fso.Resources() as IADsCollection;
Console.WriteLi ne("----- Resource info -------");
foreach(IADsRes ource resource in resources)
{
try
{
Console.WriteLi ne("\tPath: {0}\tUser: {1}\tLockCount: {2}\tName:
{3}",
resource.Path, resource.User, resource.LockCo unt,
resource.Name);
}
catch (System.IO.File NotFoundExcepti on 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
Rich

Ok to remove a session...

fso.Sessions(). Remove(sess.Nam e);

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