Folder level permissions using asp.net

[bharathreddy]

Hi,
I am developing an application in which a user can create folders and set the permission to the specific users. When the folder is screated at the first time no user should have permissions on the folder. But i found that all the users are able to access the folder.
How can I change the folder permissions using asp.net code. Thanks in advance.


Thanks & Regards

This is some code that I was playing with, it is in vb.net but you might be able to convert it

it is not my tidiest code but it basically adds the current user to the ACL for a folder and sets ' administrators ' as the owner, I had some problems setting the owner before I gave permissions

 
Imports System.IO
Imports System.Security.Permissions
Imports System.Security.Principal
 
 
Public Class Form1
 
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim self = System.Security.Principal.WindowsIdentity.GetCurrent()
        Dim Rulz = New System.Security.AccessControl.FileSystemAccessRule(self.Name, System.Security.AccessControl.FileSystemRights.FullControl, System.Security.AccessControl.AccessControlType.Allow) ' create ACL 
        Dim mydir As New DirectoryInfo("c:\test")
        Dim vals As System.Security.AccessControl.FileSystemAccessRule
        Dim x = mydir.GetAccessControl()
        Dim permlists = x.GetAccessRules(True, True, GetType(System.Security.Principal.NTAccount))
        Dim nt As New System.Security.Principal.NTAccount("", "Administrators")
        Dim gr As System.Security.Principal.IdentityReference = nt
 
        Dim tempown = x.GetOwner(GetType(System.Security.Principal.NTAccount)) ' check current owner
        MsgBox(tempown.Value)
 
        x.AddAccessRule(Rulz)  ' add ACL to X
 
        mydir.SetAccessControl(x) ' set access control oin folder using x
 
        x.SetOwner(nt) ' set owner for folder to administrators
 
        mydir.SetAccessControl(x) ' set access control oin folder using x
 
        Dim num As Integer = 0
 
        For Each vals In permlists ' check current permissions
 
            ListBox1.Items.Add(vals.IdentityReference.Value & " - " & vals.FileSystemRights.ToString)
 
             num += 1
 
        Next
 
 
 
    End Sub
End Class
