[HttpPost]中的模型值为空

我的代码存在一些问题，希望有人能帮我一把。以下是我正在处理的代码段：[HttpPost]中的模型值为空

[Authorize] 
     public ActionResult EventResults(int id) 
     { 
      List<Event> CompetitionEvents = Event.getEventsByCompetitionId(id); 
      ViewBag.CompetitionEvents = CompetitionEvents; 
      List<Person> Competitors = Competition.getCompetitorsByCompetitionID(id); 
      ViewBag.Competitors = Competitors; 
      List<Results> Results = Competition.getCompetitorResultsPairings(CompetitionEvents, Competitors); 
      ViewBag.Results = Results; 
      ViewBag.OrganizerEmail = Competition.getCompetitionById(id).OrganizerEmail; 
      return View(); 
     } 
@model BINC.Models.Results 
@using BINC.Models; 
@{ 
    var eventList = ViewBag.CompetitionEvents as List<Event>; 
    var competitorList = ViewBag.Competitors as List<Person>; 
    var resultList = ViewBag.Results as List<Results>; 
} 
<h2></h2> 
<p>Results:</p> 
    @using (Html.BeginForm()) 
     { 
      foreach (var evt in eventList) 
      { 
       <fieldset> 
        <legend>@evt.activity.Name</legend> 
        <p>Event Description: @evt.activity.Description</p> 
        @foreach (var competitor in competitorList) 
        { 
         foreach (var result in resultList) 
         { 
          if (result.EventID == evt.id && result.CompetitorEmail == competitor.Email) 
          { 
           <p>Competitor: @competitor.FirstName @competitor.LastName</p> 
           <p>Score: @result.Score</p> 
           if (ViewBag.OrganizerEmail.Equals(@User.Identity.Name)) 
           { 
            @Html.LabelFor(model => model.Score, "New Score "); 
            @Html.TextBoxFor(model => model.Score, new { maxlength = 10, style = "width:125px" }) 
            <input type="submit" name="submitButton" value="Update" /> 
           } 
          } 
         } 
        } 
       </fieldset> 
      } 
     } 
[HttpPost] 
     public ActionResult EventResults(Results res) 
     { 
      //stuff 
     }

我的问题不过是在我的结果对象上设置了分数。例如，当我将值'15'放入文本框并单击'Update'时，我将Result模型对象传递给httppost方法，它将除'score'字段之外的所有内容设置为null刚刚进入。

我是否过分复杂呢？有更容易的方法吗？

我尝试添加

@Html.HiddenFor(model => model.EventID); 
@Html.HiddenFor(model => model.CompetitorEmail);

，但似乎并没有帮助任何。

您有多个提交按钮，并且可能是问题，这还没有考虑好做法

<input type="submit" name="submitButton" value="Update" />

只保留一个在表格末尾提交按钮

Basically--确保你通过模型来查看 - 并使用Html Helpers（即TextBoxFor（）和HiddenFor）

我不认为这是提交按钮的问题 - 但可能会帮助的一件事是实际将模型传递给视图。您正在使用ViewBag传递数据。将模型传递给View，并且您的Html Helpers应该生成正确的表单名称，以便模型绑定起作用。
