C#

private static void ToFromXmlDemo()
{
    ReflectionPermission memberAccessPerm = new ReflectionPermission(ReflectionPermissionFlag.MemberAccess);
    ReflectionPermission restrictedMemberAccessPerm = new ReflectionPermission(PermissionState.None);
    restrictedMemberAccessPerm.FromXml(memberAccessPerm.ToXml());
    Console.WriteLine("Result of ToFromXml = " +
        restrictedMemberAccessPerm.ToString());
