如何获取asp.net mvc表中的行值合计

public class Item
{
    public int Id { get; set; }
    public string Name { get; set; }
    public decimal Price { get; set; }
}

public class ItemController : Controller
{
    private readonly List<Item> _items = new List<Item>
    {
        new Item { Id = 1, Name = "Item1", Price = 10.5m },
        new Item { Id = 2, Name = "Item2", Price = 20.0m },
        // ... 其他项目
    };

    public ActionResult Index()
    {
        decimal total = _items.Sum(item => item.Price);
        ViewBag.Total = total;
        return View(_items);
    }
}

@model List<Item>

<table>
    <thead>
        <tr>
            <th>ID</th>
            <th>Name</th>
            <th>Price</th>
        </tr>
    </thead>
    <tbody>
        @foreach (var item in Model)
        {
            <tr>
                <td>@item.Id</td>
                <td>@item.Name</td>
                <td>@item.Price</td>
            </tr>
        }
    </tbody>
</table>

<p>Total Price: @ViewBag.Total</p>
