有没有人知道在 mvc asp.net 中使用 CRUD 时如何上传，以便我的图像将上传到我的标题中，无论是在它自己的 div 中还是在标题中的特定 div 中，现在我可以上传里面的图片正文中的内容，但我不知道如何将其上传到标题中的徽标元素。
这是代码，所以你可以看到我希望它显示在哪里@model IEnumerable
<!DOCTYPE html>

这是创建它的控制器的一部分：
public class PictureController : Controller
{
private ItbTidCmsEntities db = new ItbTidCmsEntities();
//
// GET: /Picture/
public ActionResult Index()
{
var pictures = db.Pictures.Include("Category");
return View(pictures.ToList());
}
public ActionResult Create(int? id)
{
ViewBag.CatID = id;
var category = db.Categories.First(c => c.CatID == id.Value);
ViewBag.CatName = category.CatName;
return View();
}
//
// POST: /Picture/Create
[HttpPost]
public ActionResult Create(Picture picture)
{
if (ModelState.IsValid)
{
db.Pictures.AddObject(picture);
db.SaveChanges();
return RedirectToAction("Content", "Admin", new { id = picture.CatID });
}
ViewBag.CatID = new SelectList(db.Categories, "CatID", "CatName", picture.CatID);
return View(picture);
}
管理模式：
namespace ItbTid.Models
{
public class Admin
{
public List<Category> category { get; set; }
public List<Text> text { get; set; }
public List<Picture> picture { get; set; }
public List<Video> video { get; set; }
public List<Link> link { get; set; }
}
}
时间条目列表模型：
namespace ItbTid.Models
{
public class TimeEntryListModel
{
public IEnumerable<TimeEntry> TimeEntries { get; set; }
public SelectList Customers { get; set; }
public long? CustomerId { get; set; }
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
}
//Vi la till denna
public class RegTimeModel
{
public TimeEntryListModel TimeEntryListModel { get; set; }
public RegisterModel RegisterModel { get; set; }
public IEnumerable<Customer> customerlist { get; set; }
}
}
