上传MVC模型中包含的图像

我有以下型号:

public class Photo
{
    public int PhotoId { get; set; }
    public byte[] ImageData { get; set; }
    public DateTime DateUploaded { get; set; }
    public string Description { get; set; }
    public bool IsActive { get; set; }

}

我希望用户能够输入照片的详细信息,然后将模型发布到控制器.我的控制器动作如下:

[HttpPost]
    public ActionResult Create(WilhanWebsite.DomainClasses.Photo photo)
    {
        if (ModelState.IsValid)
        {
            photo.DateUploaded = DateTime.Now;
            _context.Photos.Add(photo);
            _context.SaveChanges();

            return RedirectToAction("Index");
        }
        //we only get here if there was a problem
        return View(photo);
    }

我的观点如下:

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


    
Photo
    

    @Html.ValidationSummary(true)

    

        @Html.LabelFor(model => model.ImageData, new { @class = "control-label col-md-2" })
        

            
        
    

    

        @Html.LabelFor(model => model.DateUploaded, new { @class = "control-label col-md-2" })
        

            @Html.EditorFor(model => model.DateUploaded)
            @Html.ValidationMessageFor(model => model.DateUploaded)
        
    

    

        @Html.LabelFor(model => model.Description, new { @class = "control-label col-md-2" })
        

            @Html.EditorFor(model => model.Description)
            @Html.ValidationMessageFor(model => model.Description)
        
    

    

        @Html.LabelFor(model => model.IsActive, new { @class = "control-label col-md-2" })
        

            @Html.EditorFor(model => model.IsActive)
            @Html.ValidationMessageFor(model => model.IsActive)
        
    

    

        

            
        
    

}

视图显示正常,允许用户从其本地磁盘中选择文件并输入其他模型详细信息.我的问题是虽然模型发布到控制器ok,但是描述,日期和IsActive标志填充正确 - 图像数据为空.

任何人都可以让我知道我需要更改什么,以便照片的字节数组包含在发布到控制器的模型中？
