我是MVC的初学者，我开发了我的图像上传脚本项目，我想在网格中显示我上传的图像，有人需要将上传的图像替换为其他图像，我的代码工作不正常，请帮助我， 形象 型号

public  class MainGroup
  {
    [DataType(DataType.ImageUrl)]
      public string Image { get; set; }
}

        @using (@Html.BeginForm("Save", "MainGroup"))
        {

<div class="editor-field">
        <input type="file" name="imageFile" id="imageFile" />
        @Html.ValidationMessageFor(model => model.Image)
    </div>
            <div class="col-md-6" style="font-family:Arial, Helvetica, sans-serif; font-size:13px;"><b>Status</b></div>
            <div class="col-md-6">

                |
                @Html.ActionLink("Delete", "Delete", new { id = item.MainGroupID })
            </td>
        </tr>
    }

您可以将文件定义为HttpFileBase属性以保存文件，然后在post方法（保存）中将文件移动到“~/Content/upload/”。然后试试看。如果图像文件可用，也可以手动检查目录

public  class MainGroup
{
  [DataType(DataType.ImageUrl)]
  public string Image { get; set; }

  public HttpFileBase ImageFile { get; set; }

 }

公共类MainGroupController:控制器 { //获取：Masters/MainGroup

    public ActionResult Save(MainGroup maingroup)
    {
        if (ModelState.IsValid)
        {
            // You can add other logic also
            if(maingroup.ImageFile!= null && maingroup.ImageFile.ContentLength > 0)
            {
               string filePath = "~/Content/Uploaded/";
               string imageUrl = System.IO.Path.Combine(filePath, maingroup.ImageFile.File.FileName);
               var objContext = new KnittingdbContext();
               maingroup.CreateId = 1;
               maingroup.Image = imageUrl;
               maingroup.ImageFile.File.SaveAs(imageUrl));
               maingroup.StatusChangeDate = System.DateTime.Now;
               maingroup.CreatedDate = System.DateTime.Now;
               maingroup.EditId = 1;
               maingroup.EditDate = System.DateTime.Now;
               objContext.MainGroups.Add(maingroup);
               objContext.SaveChanges();
              TempData["Success"] = "Saved Sucessfully";


             }      

            return RedirectToAction("MainGroupIndex", new { A = "New" });
        }
        else
        {
            return PartialView("_MainGroupCreate", maingroup);
        }


    }

您是否检查了浏览器中图像的正确渲染路径？先生，是的。我认为我的控制器工作不正确。您可以将文件定义为HttpFileBase属性以保存文件，然后在post方法（保存）中将文件移动到“~/Content/upload/”。然后再试。如果图像文件可用，您也可以手动检查目录。IR@unique您能解释一下吗？示例code@Cola请参阅此问题和更多详细信息

    public ActionResult Save(MainGroup maingroup)
    {
        if (ModelState.IsValid)
        {
            // You can add other logic also
            if(maingroup.ImageFile!= null && maingroup.ImageFile.ContentLength > 0)
            {
               string filePath = "~/Content/Uploaded/";
               string imageUrl = System.IO.Path.Combine(filePath, maingroup.ImageFile.File.FileName);
               var objContext = new KnittingdbContext();
               maingroup.CreateId = 1;
               maingroup.Image = imageUrl;
               maingroup.ImageFile.File.SaveAs(imageUrl));
               maingroup.StatusChangeDate = System.DateTime.Now;
               maingroup.CreatedDate = System.DateTime.Now;
               maingroup.EditId = 1;
               maingroup.EditDate = System.DateTime.Now;
               objContext.MainGroups.Add(maingroup);
               objContext.SaveChanges();
              TempData["Success"] = "Saved Sucessfully";


             }      

            return RedirectToAction("MainGroupIndex", new { A = "New" });
        }
        else
        {
            return PartialView("_MainGroupCreate", maingroup);
        }


    }
