sending object as link parameter inside razor view

Question

inside my mvc razor view I'm getting list of objects and inside foreach loop I'm creating links like

@{ 
    var dday = @ViewBag.Day;     
}
@foreach (var a in Model)
{
   <li>
        @Html.ActionLink(a.Name, "ProcessAction", "Home", new { ss= @a.Id, dd= dday, cc= @a.Comp}, null)            
   </li>
}

on controller side I'm getting first two variables populated and third parameter as null even @a.Comp is populated in the moment of sending inside link.

On link mouse over I'm getting third argument as Domain.Comp

Answer 1

You cannot transfer arbitrary objects as URL parameters. Restrict yourself to strings and numbers, dates can already be tricky.

In your case it looks like you should use: cc= @a.Comp.Id.

You should be able to retrieve the object serverside from its Id.
