PageController.cs 帖子

[Route("post")]
[HttpPost]
public ActionResult post(PostNewsModel model, HttpPostedFileBase imageFile)
{
    if (ModelState.IsValid)
    {
        if (imageFile != null && imageFile.ContentLength > 0)
        {
            try
            {
                var rnd = "0123456789qwertyuiopasdfghjklzxcvbnm".Scramble().Substring(0, 10);
                var random = Md5Hash.Hash(rnd);
                string path = Path.Combine(Server.MapPath("~/img/News"), Path.GetFileName(random + imageFile.FileName));
                imageFile.SaveAs(path);
                ViewBag.Message = "File uploaded successfully";
            }
            catch (Exception ex)
            {
                ViewBag.Message = "ERROR:" + ex.Message.ToString();
            }
        }

        else
        {
            ViewBag.Message = "You have not specified a file.";
        }
        if (PostNews(model, imageFile))
        {
            ViewBag.Message = "Successfully posted";
        }
        else
        {
            ViewBag.Message = "It's not valid for some reason.";
        }
    }
    else
    {
        var errors = ModelState.Select(x => x.Value.Errors)
            .Where(y => y.Count > 0)
            .ToList();
        foreach (var error in errors)
        {
            Console.WriteLine(error);
        }

        Console.WriteLine(model.PostTitle);
        Console.WriteLine(model.Content);
        Console.WriteLine(model.PostImage);
    }
    return View(model);
}

PostNewsModel.cs

public class PostNewsModel
{
    public string PostTitle { get; set; }

    public string Content { get; set; }

    public string PostImage { get; set; }

    public string PostDate { get; set; } = DateTime.Now.ToString();

    public string PostViews { get; set; } = "1";
}

当我填写表格并按“发布新闻”时，它到达了控制器中的发布功能，但传递了一个空模型（所有字段均为空）。我尝试更改字段、ID、名称等，但无法解决。还浏览了互联网，即使发现人们遇到此问题的案例，所提供的解决方案都没有为我工作。对不起新手问题，因为我对 ASP 世界很陌生。

更新：

解决了这个问题。问题是我id = "edit"在我的表格中使用了。我不知道它是如何以及为什么它不起作用。
