ASP.NET -- C# MVC5

Question

基本上我有一个网站，用户输入带有标题的图像，我想在网站上显示它。那张图片的标题。

Atm 我正在保存到一个文件夹并显示所有图像，但我无法显示标题。它只是在我做<h2>@Html.DisplayFor(m => m.title)</h2>时不会出现@

类似这样：但我想要帖子的标题。 https://i.gyazo.com/17828889116a77983f70fd8c8a4c2ebf.png

也许我需要将图像保存到数据库中？请帮我解决这个问题。

查看：

    @foreach (var image in Model.Images)
{
    <h2>@Html.DisplayFor(m => m.title)</h2>
    <div class="row">       
        <div class="col-md-8 portfolio-item">
            <img class="portrait" src="@Url.Content(image)" alt="Hejsan" />
        </div>
    </div>

}

型号

 [Table("MemeImages")]
public class UploadFileModel
{
    [Key]
    [DatabaseGenerated(System.ComponentModel.DataAnnotations.Schema.DatabaseGeneratedOption.Identity)]
    public int id { get; set; }

    public string location { get; set; }

    public IEnumerable<string> Images { get; set; }

    public int contentLength { get; set; }
    public string contentType { get; set; }

    public string userID { get; set; }

    [Required]
    [Display(Name = "Describe your post...")]
    public string title { get; set; }

    public void SavetoDatabase(UploadFileModel file)
    {
        ApplicationDbContext db = new ApplicationDbContext();                    
        db.uploadedFiles.Add(file);
        db.SaveChanges();
    }
}

控制器：

 public class MemesController : Controller
{

    private string memesDirectory = "~/Content/Images/Memes/";

    // GET: Memes/Upload
    public ActionResult Upload()
    {
        var uploadFile = new UploadFileModel();
        return View(uploadFile);
    }

    // GET: Memes/Hot
    public ActionResult Hot(UploadFileModel uploadFileModel)
    {
        //Select every image on the server memesdirectory and posts it
        uploadFileModel.Images = Directory.EnumerateFiles(Server.MapPath(memesDirectory)).Select(fn => memesDirectory + Path.GetFileName(fn));
        return View();
    }

    // GET: Memes/Trending
    public ActionResult Trending()
    {
        return View();
    }

    // GET: Memes/Fresh
    public ActionResult Fresh()
    {
        return View();
    }

    [HttpPost]
    public ActionResult Upload(UploadFileModel uploadModel)
    {         
        if(Request.Files.Count > 0)
        {
            var file = Request.Files[0];

            if(file != null && file.ContentLength > 0)
            {
                //saves image to the server
                var fileName = Path.GetFileName(file.FileName);
                var path = Path.Combine(Server.MapPath(memesDirectory), fileName);
                file.SaveAs(path);

                //saves image-related data to the database
                uploadModel.userID = User.Identity.GetUserId();
                uploadModel.location = path;
                uploadModel.contentType = file.ContentType;
                uploadModel.contentLength = file.ContentLength;


                //saves to the database
                uploadModel.SavetoDatabase(uploadModel);
            }
        }
        return RedirectToAction("Index", "Home");
    }
}

}

Answer 1

    uploadFileModel.Images = Directory.EnumerateFiles(Server.MapPath(memesDirectory)).Select(fn => memesDirectory + Path.GetFileName(fn));
    return View();

可能需要改为：

    // Add code here to get uploadFileModel from the databases
    uploadFileModel.Images = Directory.EnumerateFiles(Server.MapPath(memesDirectory)).Select(fn => memesDirectory + Path.GetFileName(fn));
    uploadFileModel.title = "something you want"; // this line may not be necessary if getting it from the database did this for you already

    return View(uploadFileModel);
