C# 如何在mvc的my controller中选中绑定到db的复选框

为什么需要将IsSeminar导入控制器的参数？ 当您发送新闻对象时，模型绑定器将为您执行此操作

因此，我的建议是：

public ActionResult Create(News news, HttpPostedFileBase NewsImageUrl,bool IsSeminar)
    {
        if (ModelState.IsValid)
        {
                string imagename = "no-photo.jpg";
                if (NewsImageUrl != null)
                {
                    imagename = Guid.NewGuid().ToString().Replace("-", "") +
                                Path.GetExtension(NewsImageUrl.FileName);
                    NewsImageUrl.SaveAs(Server.MapPath("/NewsImage/Images/" + imagename));
                    //------------------------Resize Image------------------------------
                    ImageResizer img = new ImageResizer();
                    img.Resize(Server.MapPath("/NewsImage/Images/" + imagename),
                        Server.MapPath("/NewsImage/Thumb/" + imagename));
                }
                news.NewsImageUrl = imagename;
                news.CreateDate = DateTime.Now;

            //-------------Seminar------------------------

            if (IsSeminar)
            {
                news.IsSeminar = true;
                db.Seminarparticipants.Add(new Seminarparticipants()
                {
                    NewsID = news.NewsID,
                    FullName = String.Empty,
                    Phone = String.Empty,
                    Email = String.Empty
                });
            }
            else
            {
                news.IsSeminar = false;
            }

            db.News.Add(news);
            db.SaveChanges();
                return RedirectToAction("Index");
            }

            return View(news);
        }

因为News对象具有同名的IsSeminar属性，绑定器将理解它并创建正确的对象。

我不明白这里的问题是什么？另外，请不要只转储所有代码，请创建一个问题的列表。请编写正确的视图。我建议删除所有用Html编写的内容，因为它对问题没有用处。请只添加布尔代码。谢谢你的回复，samy sammour，我已经按照你说的做了，但它给了我这个错误（一个或多个实体的验证失败。有关详细信息，请参阅“EntityValidationErrors”属性）。内部错误是什么？这意味着它使用ModelState.IsValid失败。请尝试设置断点并使我们保持最新状态我已设置断点，并在这些字段上发现问题FullName=String.Empty，Phone=String.Empty，Email=String.Empty我删除了它们并解决了问题。非常感谢这太好了，为你感到高兴，你能为其他有同样问题的人做一个回答吗？我对这个网站不是很熟悉。
