Question

我是MVC的初学者，我开发了Image Uploader，它真的很有用，但那个图像没有保存我的上传文件夹和数据库，请帮帮我。的模型

         namespace eData
{
    public class Clr
    {

        [Key]
        public int ClrID { get; set; }
        [StringLength(5, ErrorMessage = "Must be 5 characters", MinimumLength = 5)]
        [Required(ErrorMessage = "Required")]

        public string ClrCode { get; set; }


             [StringLength(25, ErrorMessage = "Must be less than 25 charcters", MinimumLength = 1)]
        [Required(ErrorMessage = "Required")]
        public string ClrName { get; set; }


        public string Remarks { get; set; }

        public bool StatusId { get; set; }


        public DateTime StatusChangeDate { get; set; }

        public int CreateBy { get; set; }

        public DateTime CreatedDate { get; set; }

        public int EditBy { get; set; }

        public DateTime EditDate { get; set; }

    public string Name { get; set; }
    public int Length { get; set; }
    public string Type { get; set; }
    }
}

Clr控制器（创建部件）

public class ClrController : Controller
    {
        // GET: Masters/Clr
        //public ActionResult Index()
        //{
        //    return View();
        //}

        public FilePathResult Image()
        {
            string filename = Request.Url.AbsolutePath.Replace("/Clr/image", "");
            string contentType = "";
            var filePath = new FileInfo(Server.MapPath("~/Uploaded") + filename);

            var index = filename.LastIndexOf(".") + 1;
            var extension = filename.Substring(index).ToUpperInvariant();

            // Fix for IE not handling jpg image types
            contentType = string.Compare(extension, "JPG") == 0 ? "image/jpeg" : string.Format("image/{0}", extension);

            return File(filePath.FullName, contentType);
        }

        [HttpPost]
        public ContentResult UploadFiles()
        {
            var r = new List<UploadFilesResult>();

            foreach (string file in Request.Files)
            {
                HttpPostedFileBase hpf = Request.Files[file] as HttpPostedFileBase;
                if (hpf.ContentLength == 0)
                    continue;

                string savedFileName = Path.Combine(Server.MapPath("~/Uploaded"), Path.GetFileName(hpf.FileName));
                hpf.SaveAs(savedFileName);

                r.Add(new UploadFilesResult()
                {
                    Name = hpf.FileName,
                    Length = hpf.ContentLength,
                    Type = hpf.ContentType
                });
            }
            return Content("{\"name\":\"" + r[0].Name + "\",\"type\":\"" + r[0].Type + "\",\"size\":\"" + string.Format("{0} bytes", r[0].Length) + "\"}", "application/json");
        }


        public ActionResult Save(Clr clr)
        {
            var objContext = new KktdbContext();
            clr.CreateBy = 1;
            clr.StatusChangeDate = System.DateTime.Now;
            clr.CreatedDate = System.DateTime.Now;
            clr.EditBy = 1;
            clr.EditDate = System.DateTime.Now;
            objContext.Clrs.Add(clr);
            objContext.SaveChanges();
            TempData["Success"] = "Saved Sucessfully";
            return RedirectToAction("ClrIndex", new { A = "New" });
