Attempted to perform an unauthorized operation
- by Lefteris Gkinis
Now I use the following code:
Public Function SetACL(ByVal filename As String, ByVal account As String, ByVal sender As Object, ByVal e As System.EventArgs) As Boolean
Try
Dim rule As FileSystemAccessRule = New FileSystemAccessRule(account, FileSystemRights.Write, AccessControlType.Allow)
Dim fp As PermissionSet = New PermissionSet(Permissions.PermissionState.Unrestricted)
fp.AddPermission(New FileIOPermission(FileIOPermissionAccess.Read, filename))
fp.AddPermission(New FileIOPermission(FileIOPermissionAccess.Write, filename))
fp.AddPermission(New FileIOPermission(FileIOPermissionAccess.PathDiscovery, filename))
fp.Assert()
Dim di As DirectoryInfo = New DirectoryInfo(Path.GetDirectoryName(filename))
SetACL = False
Dim security As DirectorySecurity = di.GetAccessControl(AccessControlSections.Access)
security.ModifyAccessRule(AccessControlModification.Add, rule, SetACL)
di.SetAccessControl(security)
Return SetACL
Catch ex As Exception
MessageBox.Show(ex.Message, "Set Security Sub", MessageBoxButtons.OK, MessageBoxIcon.Stop)
Finalize()
End Try
End Function
The Error of 'Attempted to perform an unauthorized operation' comes when i'm trying to execute the instraction
Dim security As DirectorySecurity = di.GetAccessControl(AccessControlSections.Access)
Please if anybody knows why that error comes here to respond
