ASP .NET MVC中常用的数据类型用于图像是byte数组。我们可以在模型类中将图像的属性设为byte[]类型，然后在视图中使用HtmlHelper将其以图片的形式呈现。例如：

模型类：

public class Product
{
    public int ID { get; set; }
    public string Name { get; set; }
    public byte[] ImageData { get; set; }
    public string ImageMimeType { get; set; }
}

视图：

@model Product

@{
    Layout = null;
}





    
    


    

        
@Model.Name
        
    

控制器：

public class ProductController : Controller
{
    private readonly MyDbContext db = new MyDbContext();
    
    // GET: Product/Details/5
    public ActionResult Details(int? id)
    {
        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        Product product = db.Products.Find(id);
        if (product == null)
        {
            return HttpNotFound();
        }
        return View(product);
    }
    
    // Get Image
    public ActionResult GetImage(int id)
    {
        Product product = db.Products.Find(id);
        if (product != null && product.ImageData != null)
        {
            return File(product.ImageData, product.ImageMimeType);
        }
        return null;
    }
}
