c# - 加载一对多模型

Question

我有这样的模型:

public partial class Goods
{
    public decimal good_id { get; set; }
    public string good_name { get; set; }
    public virtual ICollection<Description> description { get; set; }
}

public partial class Description
{
    public decimal des_id { get; set; }
    public decimal des_good_id { get; set; }
    public string des_name { get; set; }
    public string des_value { get; set; }
    public virtual Goods goods { get; set; }
}

对于 Goods 中的每种商品，我如何从描述模型中加载与商品具有相同 ID 的所有数据？

我的 Controller :

public ActionResult Index()
{
    var parts = _db.Goods.Include(p => p.Details);
    return View(parts.ToList());
}

这东西不工作:

@foreach (var part in Model)
{
    <div class="well">
        <div class="row">
            <div class="col-xs-10">
                <h3>
                    <strong>@part.good_name</strong>
                </h3>
                <h4>
                    <strong>@part.Description</strong>
                </h4>
            </div>
        </div>
    </div>
}

Answer 1

据我了解你的问题，你有模型，你的模型中也有一个列表，你想用列表检索数据

Here is your controller code

public ActionResult Index()
{
    var parts = _db.Goods.Include("Descriptions").Where(x=>x.good_id == id);
    return View(parts));
}

其中“id”是基于您的数据将被找到的 id

Here is your View code with razor engine

 @import YourApplicationName.Model.Goods
 @foreach (var part in @Model.Description)
 {
 <div class="well">
    <div class="row">
        <div class="col-xs-10">
            <h3>
                <strong>@part.des_name</strong>
            </h3>
            <h4>
                <strong>@part.des_value</strong>
            </h4>
        </div>
    </div>
</div>
}

Hope this is your answer
