Asp.net mvc MVC 3带模型的表单回发

我试图将我的模型发布回控制器，但FormCollection中的结果并不是我所期望的

我从我的定制XML服务收到TeamModel的IEnumerable。每个TeamModel包含一个字符串和一个bool。字符串是团队的名称，bool表示用户是否希望将其插入数据库

控制器：

public ActionResult ImportTeams()
    {
        var xmlService = new XmlSoccerService();
        const string league = "Scottish Premier League";

        var model = xmlService.GetAllTeamsByLeagueAndSeason(league, "1112");
        ViewBag.League = league; 
        return View("~/Views/Admin/Database/ImportTeams.cshtml", model);
    }

    [HttpPost]
    public ActionResult ImportTeams(FormCollection collection , string league)
    {
        return RedirectToAction("ImportTeams");
    }

public class TeamModel
{
    public string Name { get; set; }
    public bool Import { get; set; }
}

@model IEnumerable<TopTipFootball.XmlSoccer.Models.TeamModel>

@{
    ViewBag.Title = "Import Teams";
}

<h2>Select the teams to import into: @ViewBag.League</h2>

@using (Html.BeginForm())
{
    var league = ViewBag.League;

    @Html.HiddenFor(l => league)

    foreach (var team in Model)
    {
        <div class="editor-field">
            @Html.EditorFor(model => team.Import)
            @Html.DisplayFor(m => team.Name)      
        </div>
    }
    <p>
        <input type="submit" value="Import teams" />
    </p>
}

<input checked="checked" class="check-box" data-val="true" data-val-required="The Import field is required." id="team_Import" name="team.Import" type="checkbox" value="true" />
<input name="team.Import" type="hidden" value="false" />

团队模型：

public ActionResult ImportTeams()
    {
        var xmlService = new XmlSoccerService();
        const string league = "Scottish Premier League";

        var model = xmlService.GetAllTeamsByLeagueAndSeason(league, "1112");
        ViewBag.League = league; 
        return View("~/Views/Admin/Database/ImportTeams.cshtml", model);
    }

    [HttpPost]
    public ActionResult ImportTeams(FormCollection collection , string league)
    {
        return RedirectToAction("ImportTeams");
    }

public class TeamModel
{
    public string Name { get; set; }
    public bool Import { get; set; }
}

@model IEnumerable<TopTipFootball.XmlSoccer.Models.TeamModel>

@{
    ViewBag.Title = "Import Teams";
}

<h2>Select the teams to import into: @ViewBag.League</h2>

@using (Html.BeginForm())
{
    var league = ViewBag.League;

    @Html.HiddenFor(l => league)

    foreach (var team in Model)
    {
        <div class="editor-field">
            @Html.EditorFor(model => team.Import)
            @Html.DisplayFor(m => team.Name)      
        </div>
    }
    <p>
        <input type="submit" value="Import teams" />
    </p>
}

<input checked="checked" class="check-box" data-val="true" data-val-required="The Import field is required." id="team_Import" name="team.Import" type="checkbox" value="true" />
<input name="team.Import" type="hidden" value="false" />

查看：

public ActionResult ImportTeams()
    {
        var xmlService = new XmlSoccerService();
        const string league = "Scottish Premier League";

        var model = xmlService.GetAllTeamsByLeagueAndSeason(league, "1112");
        ViewBag.League = league; 
        return View("~/Views/Admin/Database/ImportTeams.cshtml", model);
    }

    [HttpPost]
    public ActionResult ImportTeams(FormCollection collection , string league)
    {
        return RedirectToAction("ImportTeams");
    }

public class TeamModel
{
    public string Name { get; set; }
    public bool Import { get; set; }
}

@model IEnumerable<TopTipFootball.XmlSoccer.Models.TeamModel>

@{
    ViewBag.Title = "Import Teams";
}

<h2>Select the teams to import into: @ViewBag.League</h2>

    @Html.HiddenFor(l => league)

    foreach (var team in Model)
    {
        <div class="editor-field">
            @Html.EditorFor(model => team.Import)
            @Html.DisplayFor(m => team.Name)

<input name="team.Import" type="hidden" value="false" />
        Aberdeen      

@model IEnumerable
@{
ViewBag.Title=“导入团队”；
}
选择要导入的团队：@ViewBag.League
@使用（Html.BeginForm（））
{
var-league=ViewBag.league；
@Html.HiddenFor（l=>league）
foreach（模型中的var团队）
{
@EditorFor（model=>team.Import）
@DisplayFor（m=>team.Name）
}


}

视图呈现html中的一个元素：

public ActionResult ImportTeams()
    {
        var xmlService = new XmlSoccerService();
        const string league = "Scottish Premier League";

        var model = xmlService.GetAllTeamsByLeagueAndSeason(league, "1112");
        ViewBag.League = league; 
        return View("~/Views/Admin/Database/ImportTeams.cshtml", model);
    }

    [HttpPost]
    public ActionResult ImportTeams(FormCollection collection , string league)
    {
        return RedirectToAction("ImportTeams");
    }

public class TeamModel
{
    public string Name { get; set; }
    public bool Import { get; set; }
}

@model IEnumerable<TopTipFootball.XmlSoccer.Models.TeamModel>

@{
    ViewBag.Title = "Import Teams";
}

<h2>Select the teams to import into: @ViewBag.League</h2>

@using (Html.BeginForm())

    var league = ViewBag.League;

    @Html.HiddenFor(l => league)

一些问题：

public ActionResult ImportTeams()
    {
        var xmlService = new XmlSoccerService();
        const string league = "Scottish Premier League";

        var model = xmlService.GetAllTeamsByLeagueAndSeason(league, "1112");
        ViewBag.League = league; 
        return View("~/Views/Admin/Database/ImportTeams.cshtml", model);
    }

    [HttpPost]
    public ActionResult ImportTeams(FormCollection collection , string league)
    {
        return RedirectToAction("ImportTeams");
    }

public class TeamModel
{
    public string Name { get; set; }
    public bool Import { get; set; }
}

@model IEnumerable<TopTipFootball.XmlSoccer.Models.TeamModel>

@{
    ViewBag.Title = "Import Teams";
}

<h2>Select the teams to import into: @ViewBag.League</h2>

@using (Html.BeginForm())
{
    var league = ViewBag.League;

    @Html.HiddenFor(l => league)

    foreach (var team in Model)
    {
        <div class="editor-field">
            @Html.EditorFor(model => team.Import)
            @Html.DisplayFor(m => team.Name)      
        </div>
    }
    <p>
        <input type="submit" value="Import teams" />
    </p>
}

<input checked="checked" class="check-box" data-val="true" data-val-required="The Import field is required." id="team_Import" name="team.Import" type="checkbox" value="true" />
<input name="team.Import" type="hidden" value="false" />

我如何确保在返回控制器的帖子中返回TeamModel的IEnumerable

我是否打算以正确的方式将联赛传还给主控官？（通过隐藏字段）

---

尝试使用for循环来进行循环

for(int i = 0; i < Model.Count; i++) 
{
   @Html.EditorFor(model => Model[i].Import)
   @Html.DisplayFor(m => Model[i].Name)  
}

for（int i=0；imodel[i].Import）
@DisplayFor（m=>Model[i].Name）
}

我相信这应该会创建id和名称，比如Model_0_Import等，希望这会使它正确绑定到您的帖子上

是的，我用这种方式使用了隐藏字段。我当然认为联赛的排名是正确的，而这仅仅是一张不正确的项目列表

编辑：您可以一直使用viewModel，而不是使用viewBag和Model的组合

这里有一个解决方案可以提供一些帮助

public ActionResult ImportTeams()
{
    const string league = "Scottish Premier League";

    var viewModel = new LeagueTeamViewModel
    {
       League = league;
    }

    var xmlService = new XmlSoccerService();        
    var model = xmlService.GetAllTeamsByLeagueAndSeason(league, "1112");

    viewModel.Teams.AddRange(xmlService.GetAllTeamsByLeagueAndSeason(league, "1112").Select(p => new TeamViewModel
    {
       Name = p.Name,
       Import = p.Import
    };

    return View("ImportTeams", viewModel);
}

[HttpPost]
public ActionResult ImportTeams(LeagueTeamViewModel viewModel)
{
}

public class LeagueTeamViewModel 
{
   public string League { get; set; }

   private List<TeamViewModel> _teams = new List<TeamViewModel>();

   public List<TeamViewModel> Teams
   {
      get { return _teams; }
      set { _teams = value; }
   }
}

public class TeamViewModel
{
   [DisplayName("Name")]
   public string Name { get; set; |

   [DisplayName("Imported")]
   public string Import { get; set; |
}

public ActionResult importItems（）
{
const string league=“苏格兰超级联赛”；
var viewModel=新的LeagueTeamViewModel
{
联盟=联盟；
}
var xmlService=new XmlSoccerService（）；
var模型=xmlService.GetAllTeamsByLeagueAndSeason（联盟，“1112”）；
viewModel.Teams.AddRange（xmlService.GetAllTeamsByLeagueAndSeason（league，“1112”）。选择（p=>new TeamViewModel
{
名称=p.名称，
导入=p.导入
};
返回视图（“导入”，视图模型）；
}
[HttpPost]
公共行动结果导入（LeagueTeamViewModel viewModel）
{
}
公共类LeagueTeamViewModel
{
公共字符串联盟{get；set；}
私有列表_teams=新列表（）；
公开名单小组
{
获取{return\u teams；}
设置{u=value；}
}
}
公共类TeamViewModel
{
[显示名称（“名称”）]
公共字符串名称{get；set|
[显示名称（“导入”）]
公共字符串导入{get；set|
}

你的看法呢

@model IEnumerable<LeagueTeamViewModel>
@{
    ViewBag.Title = "Import Teams";
}

<h2>Select the teams to import into: @Model.League</h2>

@using (Html.BeginForm())
{
    @Html.HiddenFor(model => model.League)

    for(int i = 0; i < Model.Teams.Count; i++) 
    {
        <div class="editor-field">
            @Html.EditorFor(model => model.Teams[i].Import)
            @Html.HiddenFor(m => model.Teams[i].Name)      
        </div>
    }
    <p>
        <input type="submit" value="Import teams" />
    </p>
}

@model IEnumerable
@{
ViewBag.Title=“导入团队”；
}
选择要导入的团队：@Model.League
@使用（Html.BeginForm（））
{
@HiddenFor（model=>model.League）
对于（int i=0；imodel.Teams[i].Import）
@Html.HiddenFor（m=>model.Teams[i].Name）
}


}

嘿，谢谢。是的，效果很好。我必须改为列表而不是IEnumerable，但这没有问题。我还必须为球队名称添加另一个隐藏字段，因为DisplayFor只输出文本而不是表单字段。现在又出现了一个问题，现在模型绑定到控制器中，联盟返回为b长串。这正常吗？是另一种吗？嗯，你可以试试@Html.Hidden（“league”，league）但是如果你问我的话，那就有点不对劲了。我刚刚在上面的答案中看到了你的编辑。当然，选择viewmodel路线似乎比使用ViewBag要干净得多。非常感谢你的帮助。希望它对你有用。viewmodel并不总是完美的解决方案，但在适当的情况下可以派上用场
