Question

我可以使用mvc 4 razor上传图像文件。现在我想显示/查看这些图像。我正在使用图像的产品。所以，我想展示特定产品的图像。如何显示与该产品相关的图像？

这是我的模特：

namespace Online_Shopping_Management.Models
{
  public class Product
  {
    [Key]
    public int ProductId { set; get; }
    public int? CategoryId { set; get; }
    public virtual Category Category { set; get; }
    public int? SubCategoryId { set; get; }
    public virtual SubCategory SubCategory { set; get; }
    public int? ModelId { set; get; }
    public virtual Model Model { set; get; }
    public string ProductName { set; get; }
    public string Number { set; get; }
    public string Color { set; get; }
    public decimal StandardCost { set; get; }
    public decimal ListPrice { set; get; }
    public string Size { set; get; }
    public double Weight { set; get; }
    public DateTime ProductionDate { set; get; }
    public DateTime ExperiedDate { set; get; }

    public IEnumerable<HttpPostedFileBase> Files { get; set; }
  }
}

这是我的控制器部分：

 public ActionResult Create(Product product)
    {
        foreach (var file in product.Files)
        {
            if (file.ContentLength > 0)
            {
                var fileName = Path.GetFileName(file.FileName);
                var path = Path.Combine(Server.MapPath("~/Content/images"), fileName);
                file.SaveAs(path);
            }
        }
        if (ModelState.IsValid)
        {
            db.Products.Add(product);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        ViewBag.CategoryId = new SelectList(db.Categorys, "CategoryId", "Name", product.CategoryId);
        ViewBag.SubCategoryId = new SelectList(db.SubCategories, "SubCategoryId", "SubCategoryName", product.SubCategoryId);
        ViewBag.ModelId = new SelectList(db.Models, "ModelId", "ModelName", product.ModelId);
        return View(product);
    }

这是我的观点部分：

@model IEnumerable<Online_Shopping_Management.Models.Category>

@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

<p>
 Select from @Model.Count() categories:
</p>

<ul>
@foreach (var categories in Model)
{
    <li>@Html.ActionLink(categories.Name, "Browse", new { categories = categories.Name })</li>
}
</ul>
