How to add a collection, for example. dynamic array as a property of an asp.net user control?

Question

I am trying to add a dynamically extensible property to a composite control that I can remove on the surface of the constructor. I tried this with String Array, List and ArrayList. All with similar results. I’m missing something, and I don’t know what. Here is what I consider the appropriate code:

    [DesignerSerializationVisibility(DesignerSerializationVisibility.Content), 
    NotifyParentProperty(true),
    PersistenceMode(PersistenceMode.InnerProperty)]
    public String[] AccessLevels
    {
        get
        {
            String[] s = (String[])ViewState["AccessLevels"];
            return s;
        }

        set
        {
            ViewState["AccessLevels"] = value;
        }
    }

, . "" Visual Studio 2008 "+ AccessLevels" "String [] Array" elipsis [...]. elipsis, , . " " "AccessLevels", , , , . ! , , , HTML- .

    <cc2:HBAdmin ID="HBAdmin1" runat="server">

        <system.string></system.string>
        <system.string></system.string>
        </AccessLevels>
    </cc2:HBAdmin>
