我正在尝试在网格视图中显示图像，但我不能这样做只有图像名称正在显示，请建议我解决方案

Question

1. 这是我的控制器

   [HttpPost]
           public ActionResult Create([Bind] Employee emp, HttpPostedFileBase Photo)
           {
               try
               {
                   if (Photo.ContentLength > 0)
                   {
                       string _ImageName = Path.GetFileName(Photo.FileName);
                       string _path = Path.Combine(Server.MapPath("~/Upload/" + _ImageName), _ImageName);
                       Photo.SaveAs(Server.MapPath(_path));
   
                       objemployee.AddEmployee(emp);
                       ViewBag.Message = "Image Uploaded Successfully!!";
                       return View();
                   }
                   else if (ModelState.IsValid)
                   {
                       objemployee.AddEmployee(emp);
                       return RedirectToAction("Index");
                   }
                   return View(emp);
               }
               catch
               {
                   objemployee.AddEmployee(emp);
                   //return Json(new { msg = "1" }, JsonRequestBehavior.AllowGet);
                   return View();
               }
   
           }
   

2. 添加数据的代码

   public void AddEmployee(Employee emp)
           {
               using (SqlConnection con = new SqlConnection(ConnectionString))
               {
                   SqlCommand cmd = new SqlCommand("spaddEmployee", con);
                   cmd.CommandType = CommandType.StoredProcedure;
                   cmd.Parameters.AddWithValue("@FirstName", emp.FirstName);
                   cmd.Parameters.AddWithValue("@LastName", emp.LastName);
                   cmd.Parameters.AddWithValue("@Gender", emp.Gender);
                   cmd.Parameters.AddWithValue("@DOB", Convert.ToDateTime(emp.DOB));
                   cmd.Parameters.AddWithValue("@Hobby", emp.Hobby);
                   cmd.Parameters.AddWithValue("@Photo", emp.Photo);
                   cmd.Parameters.AddWithValue("@City", emp.City);
   
                   con.Open();
                   cmd.ExecuteNonQuery();
                   con.Close();
               }
           }
   

3. 以下是我的创建和索引视图，数据显示在索引页面上

   @Html.LabelFor(model => model.Photo, htmlAttributes: new { @class= "control-label col-md-2" }) @Html.TextBox("Photo", "", new { type = "file" })
   
   @Html.ValidationMessageFor(model => model.Photo, "", new { @class= "text-danger" })

Answer 1

您不仅要存储图像名称，还要将同一图像的路径存储到数据库中。
