c# - 从 MVC 编辑页面/视图上传文件

Question

我有一个带有标准编辑视图的非常基本的 mvc 项目，我正在尝试添加直接从该视图上传文件的选项。

我已经从 Create 视图成功实现了上传选项，但由于某种原因它在 Edit 视图中不起作用。

编辑视图（文件上传和保存）

<div class="form-group">
    @Html.Label("Attach File", new { @class = "control-label col-md-2" })
    <div class="col-md-10">
        <input type="file" id="file" name="upload" />
    </div>
</div>

<div>
    <input type="submit" value="Save" class="btn btn-default" />
</div>

编辑控制器

    // POST: Travel/Edit/5
    // To protect from overposting attacks, please enable the specific properties you want to bind to, for 
    // more details see https://go.microsoft.com/fwlink/?LinkId=317598.
    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Edit([Bind(Include = "TravelID,RequestedBy,DateRequested,TravelDescription,DestinationCity,DestinationState,StartDate,EndDate,EstRegistrationPerPerson,EstAirfarePerPerson,EstGroundPerPerson,EstLodgingPerPerson,EstMealsPerPerson,DepartureCity,DepartureState,DepartureDate,DepartureTimeRange,ReturnFromCity,ReturnFromState,ReturnFromDate,ReturnFromTimeRange,FlightNote,Hotel,HotelPhone,HotelNote,NeedHotelArrangements,NeedFlightArrangements,NeedRentalCarArrangements,IsTripInTravelBudget,Justification,OtherNote,SupAuth,SupAuthDate,CEOAuth,CEOAuthDate,ActRegistrationPerPerson,ActAirfarePerPerson,ActGroundPerPerson,ActLodgingPerPerson,ActMealsPerPerson")] Travel travel, HttpPostedFileBase upload)
    {
        if (ModelState.IsValid)
        {
            if (upload != null && upload.ContentLength > 0)
            {
                var file = new Files
                {
                    TravelID = travel.TravelID,
                    FileName = System.IO.Path.GetFileName(upload.FileName),
                    FileType = upload.ContentType
                };
                using (var reader = new System.IO.BinaryReader(upload.InputStream))
                {
                    file.Content = reader.ReadBytes(upload.ContentLength);
                }
                travel.Files = new List<Files> { file };
            }
            db.Entry(travel).State = EntityState.Modified;
            db.SaveChanges();
            return RedirectToAction("Details", "Travel", new { id = travel.TravelID });
        }
        return View(travel);
    }

当我提交编辑时，所有其他字段都会按预期更新，但没有上传文件。

文件型号：

namespace TrainingAndTravel.Models
{
    using System;
    using System.Collections.Generic;

    public partial class Files
    {
        public int FileID { get; set; }
        public int TravelID { get; set; }
        public string FileName { get; set; }
        public string FileType { get; set; }

我不得不重新排列我的控制器，将上传部分放在 EntityState.Modified 和 SaveChanges 下方，还需要在上传下方有一个 db.SaveChanges()：

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Edit([Bind(Include = "TravelID,RequestedBy,DateRequested,TravelDescription,DestinationCity,DestinationState,StartDate,EndDate,EstRegistrationPerPerson,EstAirfarePerPerson,EstGroundPerPerson,EstLodgingPerPerson,EstMealsPerPerson,DepartureCity,DepartureState,DepartureDate,DepartureTimeRange,ReturnFromCity,ReturnFromState,ReturnFromDate,ReturnFromTimeRange,FlightNote,Hotel,HotelPhone,HotelNote,NeedHotelArrangements,NeedFlightArrangements,NeedRentalCarArrangements,IsTripInTravelBudget,Justification,OtherNote,SupAuth,SupAuthDate,CEOAuth,CEOAuthDate,ActRegistrationPerPerson,ActAirfarePerPerson,ActGroundPerPerson,ActLodgingPerPerson,ActMealsPerPerson")] Travel travel, HttpPostedFileBase upload)
{
    if (ModelState.IsValid)
    {
        db.Entry(travel).State = EntityState.Modified;
        db.SaveChanges();
        if (upload != null && upload.ContentLength > 0)
        {
            var file = new Files
            {
                FileName = System.IO.Path.GetFileName(upload.FileName),
                FileType = upload.ContentType
            };
            using (var reader = new System.IO.BinaryReader(upload.InputStream))
            {
                file.Content = reader.ReadBytes(upload.ContentLength);
            }
            travel.Files = new List<Files> { file };
        }
        db.SaveChanges();
        return RedirectToAction("Details", "Travel", new { id = travel.TravelID });
    }
    return View(travel);
}
