Hi
Is there a way I can fnd the Owner of a folder, using vb.net? I know how to
find the permissions, but I can't figure how to find the owner.
Thanks

1. Create a DirectoryInfo object
2. Call it's GetAccessControl method. It returns a DirectorySecurity
object.
3. Call the GetOwner method of the returned object. Something like this:

Dim sidType As Type =
GetType(System.Security.Principal.SecurityIdentifier)
Dim owner As System.Security.Principal.SecurityIdentifier

owner = DirectCast(DS.GetOwner(sidType),
Security.Principal.SecurityIdentifier)

(DS is the DirectorySecurity object)

4. Owner is the owner. :)

Thanks AZ for your reply!

Hi Simeon,

As AZ has suggested, we can get the DirectorySecurity object by calling
DirectoryInfo.GetAccessControl method first and then get the owner by
calling the DirectorySecurity.GetOwner method passing NTAccount as the
parameter.

The following is a sample:

Imports System.IO
Imports System.Security.AccessControl
Imports System.Security.Principal

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
Dim di As New DirectoryInfo("directoryname")
Dim ds As DirectorySecurity = di.GetAccessControl()
Dim owner As NTAccount = CType(ds.GetOwner(GetType(NTAccount)),
NTAccount)
End Sub

Hope this helps.
If you have any question, please feel free to let me know.

Hi,
To make syntax shorter, "my" namespace can also be used:
Dim owner As NTAccount =3D _ My.Computer.FileSystem.GetDirectoryInfo("c:
\resized").GetAccessControl.GetOwner(GetType(NTAccount))

Thanks,

==========

I think Linda Liu's example is exactly the same, but just split into
some lines to make the steps easier to understand.

The My namespaces is not required at all. At least in this case it's not
the direct way. The call is delegated to
Microsoft.VisualBasic.FileIO.FileSystem.GetDirectoryInfo which again
creates a Sytem.IO.DirectoryInfo object. So, I'd directly do the latter
and get rid of the superfluous My-garbage.
