public class Cartviewmodel
{
    public List<CartItem> CartItems { get; set; }
    public decimal CartTotal { get; set; }
}

获取Cart的控制器,将其映射到视图模型并传递它

public ActionResult GetCartSummary()
{
    var cart = Cart.Instance;
    var viewmodel = AutoMapper.Mapper.Map<Cart,Cartviewmodel>(cart);
    return View(viewmodel);
}

并对此有所了解

@model TheWorkshop.Web.Models.Edit.ShoppingCartviewmodel

<h2>Cart Summary</h2>
<span>@Model.CartTotal</span>

最后在我的_Layout.cshtml文件中

@Html.Action("GetCartSummary","Cart")

但这给了我
