Question

我正在开发一个有关电子学习的项目，我需要上传视频。我使用asp.net MVC作为前端，并使用sql server 2017作为后端。如何上传视频并将其路径保存在数据库中，以便稍后检索它以显示视频我已经尝试过这段代码，但是路径没有保存到数据库中，并且没有错误

这是我的模特

 public class Video
    {
        public int VideoID { get; set; }
        public int CourseID { get; set; }
        [Required]
        [StringLength(100, ErrorMessage = "Please enter the title for the Video")]
        public string Title { get; set; }
        public string Path { get; set; }
        public int CourseName { get; set; }

        public virtual ECourse Course { get; set; }
    }

cotroller

 public ActionResult Create()
        {
            return View();
        }


        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult Create([Bind(Include = "VideoID,CourseID,Title,Path,CourseName")] Video video)
        {

            if (ModelState.IsValid)
            {
                db.Videos.Add(video);
                db.SaveChanges();
                return RedirectToAction("Index");
            }

            return View(video);
        }

查看

@model eLearning.Models.Video

@{
    ViewBag.Title = "Create";
}

<h2>Create</h2>

@using (Html.BeginForm()) 
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">

            </div>
        </div>
