c# - 获取由 foreach 循环 mvc 生成的选中复选框

Question

我在将选中的复选框放入我的 mvc Controller 并将它们保存在数据库中时遇到问题。我在创建 View 中使用 for each 循环生成了我的列表。

我的广告类:

    public class Advert
  {
    public int AdvertId { get; set; }
    public int SponsorId { get; set; }
    [DisplayName("Amount")]
    public int Amount { get; set; }


    [DisplayName("Start date")]
    [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yy}")]
    [DataType(DataType.Date)]
    public System.DateTime StartDate { get; set; }

    [DisplayName("End date")]
    [DataType(DataType.Date)]
    [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yy}")]
    public DateTime EndDate { get; set; }

    public List<Continent> Continents { get; set; }
    public List<Country> Countries { get; set; }
    public List<Sport> Sports { get; set; }
    public Gender Gender { get; set; }
    public Sponsor Sponsor { get; set; }
    public int SponsorTypeId { get; set; }
  }

(部分)创建 View

    <div class="editor-label">
    @Html.LabelFor(model => model.SponsorId, "Select sport")
</div>

<div class="editor-field">
    @foreach (var item in Model.Sports)
    {
            <tr>
                <td>
                    <input type="checkbox" id="@item.SportId" name="SelectedSport" value="@item.SportId"/>
                </td>
                <td>
                    @item.SportName
                </td>
            </tr> <br />  
    }   
</div>

广告 Controller

// POST: /Advert/Create
[HttpPost]
public ActionResult Create(Advert advert)
{
  ViewBag.SponsorId = new SelectList(db.Sponsors, "SponsorId", "SponsorCompany", advert.SponsorId);
  advert.SponsorTypeId = service.sponsorType(advert.Amount);   

    if (ModelState.IsValid)
    {
      db.Adverts.Add(advert);
      db.SaveChanges();
      return RedirectToAction("Index");
    }

    return View(advert);
}

我真的被困在这一点上了一段时间，所以欢迎任何帮助!

Answer 1

如果您只是想获取 ID，那么最直接的方法是使用命名参数。

<input type="checkbox" id="myParams" name="myParams" value="@item.SportId"/>

然后只需更改您的定义以按名称拉出该列表

public ActionResult Create(Advert advert, string[] myParams)
