ASP.Net模型（GET）没有显示价值

Question

映射我的模型但值不是设置......很奇怪，

public ActionResult Appointment(string date = null, string id)
{
    // Do stuff
    var rId = _resource.Find(id)
    var model = new ViewModels.AppointmentNew()
    {
        ResourceId = rId;
    }
    return View("Appointment", model);
}

HTML \视图

@Html.HiddenFor(model => model.ResourceId)
@Html.HiddenFor(model => model.Id)

HTML渲染

<input id="ResourceId" name="ResourceId" type="hidden" value="">

查看viewdata＆gt;模型

已针对ResourceId设置了值... 想法？
