如何获得asp mvc中列表的复选框值

Question

我使用下面的代码来创建一个包含动态计数的列表。当我在我的动作中得到模型时，复选框值为null（即使当我检查它们时）。

我的模型：

public partial class Job_SharhVazife 
{ 
    public int ID { get; set; } 
    public Nullable<int> Job_Id { get; set; } 
    public string Name { get; set; } 
    public Nullable<bool> Asli { get; set; } 
    public Nullable<bool> Mostamar { get; set; } 
    public Nullable<int> Dore { get; set; } 
    public Nullable<bool> Tafviz { get; set; } 

    public virtual Job_MainJob Job_MainJob { get; set; } 
    public virtual Job_SharhVazife_Dore Job_SharhVazife_Dore { get; set; } 
} 
public class AllDataOfMainJob 
{ 
    public IEnumerable<Job_SharhVazife> Job_SharhVazife { get; set; } 
} 

我的html代码：

@model JobWebApplication.Models.AllDataOfMainJob 
... 
    <div class="form-group"> 
     @Html.LabelFor(model => model.Job_SharhVazife, htmlAttributes: new { @class = "control-label col-md-2" }) 
      <div class="col-md-10"> 
       <div class="table-responsive"> 
        <table id="tblSharhVazife" class="table"> 
         <thead> 
          <tr> 
           <th>@Html.Label("Row")</th> 
           <th>@Html.Label("Header1-text")</th> 
           <th>@Html.Label("Header2-checkbox")</th> 
           <th>@Html.Label("Header3-checkbox")</th> 
           <th>@Html.Label("Header4-dropdown")</th> 
           <th>@Html.Label("Header5-checkbox")</th> 
          </tr> 
         </thead> 
         <tbody> 
          @if (Model.Job_SharhVazife != null) 
          { 
           for (int i = 0; i < Model.Job_SharhVazife.Count(); i++) 
           { 
           <tr> 
            <td>@((i + 1).ToString())</td> 
            <td><input class="form-control text-box single-line valid" id=@("Job_SharhVazife_" + @i + "__Name") name="Job_SharhVazife[@i].Name" type="text" value="@Model.Job_SharhVazife.ToList()[i].Name"></td> 
            <td>

               { <text> checked="checked" </text> } /><span class="text"></span>

我测试的代码，我用MVC剃刀HTML助手代替HTML

@Html.CheckBoxFor(x => Model.Job_SharhVazife[i].Asli) 

，并为所有属性和它现在正在工作，但是您必须将Job_SharhVazife更改为List而不是IEnumerable和所有bool? to bool，您可以将false添加为默认值。
