如何从表格上传文件

Question

我有一个6行的表，每行有2列（文件标题和附件文件）。

HTML表行如下所示：

            <tr>
                <td>1</td>
                <td>
                    <input type="text" id="Attachment_Desc1" name="Job_Requests_Det[1].Attachment_Desc" uniqueid="1" class="form-control" required="">
                </td>
                <td>
                    <input type="file" id="Attachment_Path1" name="Job_Requests_Det[1].Attachment_File" class="file-styled" required="required">
                </td>
            </tr>

我想保存表记录，但是当我提交表单时，每次尝试编辑代码时，列表上只有一条记录

这是我在控制器上的代码：

public ActionResult Create([Bind(Include = "Job_Request_ID,Attachment_Desc,Attachment_Path")] Job_Requests job_Requests,
    List<Job_Requests_Det> Job_Requests_Det)
{
    if (Job_Requests_Det != null)
    {
        if (Job_Requests_Det.Count > 0)
        {
            for (int i = 0; i < Job_Requests_Det.Count; i++)
            {
                if (Job_Requests_Det[i].Attachment_Desc == null)
                    continue;
                var requestDet = new Job_Requests_Det();
                //requestDet.Job_Request_ID = job_Requests.Job_Request_ID;
                requestDet.Attachment_Desc = Job_Requests_Det[i].Attachment_Desc;
                if (Request.Files != null)
                {
                    for (int x = 0; x < Request.Files.Count; x++)
                    {
                        HttpPostedFileBase f = Request.Files[x];
                        if (f.FileName == "")
                            continue;
                        string tmpf = Guid.NewGuid().ToString() + f.FileName;
                        string path = Path.Combine(Server.MapPath("~/UploadDir/Applicants/"), tmpf);
                        f.SaveAs(path);
                        requestDet.Attachment_Path = tmpf;
                    }
                }
                db.Job_Requests_Det.Add(requestDet);
            }
        }
    }

    int Rows = db.SaveChanges();//update
    if (Rows == 0)
    {
        return Json("error", JsonRequestBehavior.AllowGet);
    }
    return View();
}

您能帮我找到错误吗？
