Create directory and apply write permissions to it

I want to create a folder in either My Documents or the Public\Users folders on XP and Vista.

I can create the folder using Directory.CreateDirectory without any problem. However, it defaults to ReadOnly.

I've tried using the DirectorySecurity overload but cannot get it to work.

When I try the AddDirectorySecurity method, I get teh error message "AddDirectorySecurity" is not declared.

If I change to DirectorySecurity (as suggested by Visual Studio) I am told it is " a type and cannot be used as an expression.

Can someone point me in the right direction please?

Many thanks
Imports System

Imports System.IO

Imports System.Security.AccessControl
 

Public Class MyClass

Try

    If Directory.Exists(fullPath.ToString()) = False Then

        Directory.CreateDirectory(fullPath.ToString())

        AddDirectorySecurity(fullPath.ToString()), "DOMAIN\MyUser", FileSystemRights.WriteData, AccessControlType.Allow)

    End If

Catch ex As Exception
 

End Try

...

End Class
