How to Reference an Existing Hashtable

P: n/a
I am working with Sharepoint Services and am trying to add the
fileversion Metadata to the Versions.aspx page using the example from
the SDK. I have not done much with hashtables but it all looks
straightforward in the SDK.
The code segment added is below. The commented out lines (<!-- )are for
testing and work correctly. i.e. I can create a NEW hashtable, add
items to it, and display them on the Versions.aspx page. When I try to
create a new Hashtable from the Properties of the SPFileVersion Class I
get an error.

<% Hashtable hash = ver.Properties; %> This line creates the error.

Clearly I am referencing 'ver.Properties' incorrectly but i can't
figure it out.
<TD class="ms-vb2" valign="top">
<% Hashtable hash = ver.Properties; %>
<!-- Hashtable hash = new Hashtable();-->
<!-- hash.Add("First", "Hello");-->
<!-- hash.Add("Second", "World");-->
<!-- hash.Add("Third", "!");-->
<% ICollection keys = hash.Keys; %>
<% foreach (object key in keys) %>
<% { %>
<% Response.Write(SPEncode.HtmlEn*code(key.ToString() ) + " :: " +
SPEncode.HtmlEncode(hash[key.T*oString()].ToString()) + "<BR>"); %>
<% } %>
</TD>
The SDK reference for this is the Properties (gets metadata for the
fileversion):
http://msdn.microsoft.com/library/de...SV01013560.asp

Any clues?
