html.actionlink htmlattributes dictionary bug?

I am trying to use the Html.Actionlink overload that takes and IDictionary<String, Object> as the htmlAttributes parameter.To simplify it, look at this example:

@Html.ActionLink("TEST", "Test", new { test = 1 }, new Dictionary<string, object>())

That is outputting the following HTML:

<a Comparer="System.Collections.Generic.GenericEqualityComparer`1[System.String]" Count="0" Keys="System.Collections.Generic.Dictionary`2+KeyCollection[System.String,System.Object]" Values="System.Collections.Generic.Dictionary`2+ValueCollection[System.String,System.Object]" href="/Controller/Test?test=1">TEST</a>

i.e. it is writing out all the internal properies of the Dictionary object rather than that acual key value pairs within it.

Obviously, I have tried it with actual data in the dictionary too and the same thing happens.

Am i doing something silly, or is that a bug?

Thanks

Thanks, but that relates to the Route Value parameter - my query is about that htmlAttributes which is an IDictionary<String, Object> according to the help file (and Intellisense)

SOmeone on forums.asp.net helped me with this.  

If instead of using an anonymous type for the RouteValueDictionary as i was doing previously and instead use the explicit declaration:

new RouteValueDictionary(new { id = 1 })

then the problem with the HtmlAttributes dictionary goes away.

I guess this must be because the:

ActionLink(HtmlHelper, String, String, Object, Object)

overload was being used and it therefore wasnt seeing the dictionary as a dictionary - i.e. was iterating through the standard object properties instead
