Assuming you are using the default routes:

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute(
        "Default",
        "{controller}/{action}/{id}",
        new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    );
}

If you need to specify the controller name try this (don’t forget the last parameter – the html attributes which I am passing to null here):

<%: Html.ActionLink("Contacts", "Index", "Contacts", new { id = item.CompanyID }, null) %>

or without specifying the controller (using the current controller):

<%: Html.ActionLink("Contacts", "Index", new { id = item.CompanyID }) %>
