Passing Parameters to an ASP.Net MVC2 Action from JQuery Autocomplete

I'm trying to pass 2 parameters from JQuery's Autocomplete plugin to an ASP.Net MVC2 Action, see script below. The Controller is name开发者_如何转开发d EntityController, and the Action is named AddSharedUser, which takes 2 strings, see Action also copied below. When I try to run it it tries to pass in "AddSharedUser" as a single parameter, and fails. Any ideas where I've gone wrong?

   { %>
           <li>
           <%: item.Name%>
           <%: Html.ActionLink("Remove", "RemoveSharedUser", "Entity", 
                new { id = Model.EntityId, CustId = item.CustId }, null)%>
           </li>
<% } %>
</ul>
<form id="search_for_entity_user" method="get" action="<%=  Url.Action("AddSharedUser",     "Entity") %>">

public ActionResult AddSharedUser(string id, string name)

    //Trying to use the parameters here

    return View();
}

When posting trough jquery/ajax you have to post as,

'<%= Url.Action("AddSharedUser", "Entity") %>' + 'id=42&name=Russ'

Not exactly sure what ^ makes up so if it doesnt work try:

 '/Entity/AddSharedUser?id=42&name=Russ'

or try specifying the parameters in the UrlAction

'<%= Url.Action("AddSharedUser", "Entity", new { id = "42", name = "Russ" }) %>'
