NoteNote

The code example is intended to show the behavior of the method, not to demonstrate its use. In general, the methods of permission classes are used by the security infrastructure; they are not typically used in applications.


    Private Shared Sub ToFromXmlDemo()
        Dim memberAccessPerm As New ReflectionPermission(ReflectionPermissionFlag.MemberAccess)
        Dim restrictedMemberAccessPerm As New ReflectionPermission(PermissionState.None)
        restrictedMemberAccessPerm.FromXml(memberAccessPerm.ToXml())
        Console.WriteLine("Result of ToFromXml = " + restrictedMemberAccessPerm.ToString())

    End Sub 'ToFromXmlDemo
End Class 'ReflectionPermissionDemo
