我想在视图中将数据从窗体发送到控制器，但是在调试模式下，它说value为空。 我没有尝试使用视图模型，但它发送null。 我的请求包含文件，我想保存视频路径以进行建模 这就是我尝试过的。 这是控制器代码
[HttpPost]
public ActionResult Create([Bind(Include = "Id,Title,Title_eng,Title_ar,Description,Description_en,Description_ar,VideoPath")] Video video)
{
var videos = db.Videos.ToList();
var rnd = new Random();
var guid = rnd.Next(999);
var file = HttpContext.Request.Files["file"];
}
这是我的视频模型
public class Video
{
public int Id { get; set; }
public string Title{ get; set; }
public string Title_en { get; set; }
public string Title_ar { get; set; }
[AllowHtml]
public string Description { get; set; }
[AllowHtml]
public string Description_en { get; set; }
[AllowHtml]
public string Description_ar { get; set; }
public string VideoPath{ get; set; }
[NotMapped]
public HttpPostedFileBase file { get; set; }
}
这是我的看法

谢谢您的帮助。
我不知道它是否相关，但是我在动作中使用了ValidateAntiforgeryTokan注释，然后可以使用ViewModel获取表单数据并在我的请求中获取文件。
答案 0 :(得分：1)
从您的查看代码中，我可以看到您没有绑定任何名为VideoPath或文件的模型属性，因此模型无法绑定您的属性值。 在声明文件属性时，您需要将此属性绑定为如下所示的视图
@Html.TextBoxFor(model => model.File, new {@class = "form-control", @type = "file"})
然后，您将获得模型的文件对象，如下所示声明属性
private HttpPostedFileBase _file;
[DataType(DataType.Upload)]
public HttpPostedFileBase File
{
get { return _file; }
set { _file = value; }
}
然后从控制器
[HttpPost]
public ActionResult SaveVideo(Video data)
{
try
{
if (ModelState.IsValid)
{
var uplodedFile = data.File;
//you will get file path from this object property.
//do other work here
}
catch(Exception e){throw;}
}
