Question

我使用下面的代码来创建一个包含动态计数的列表。当我在我的操作中获得模型时，复选框值为null（即使我检查它们）。

我的模特：

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>

                            {
                                for (int i = 0; i < Model.Job_SharhVazife.Count(); i++)

我测试代码并用MVC razor html Helper替换HTML

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

并且对于所有属性并且它现在正常工作，但您必须将Job_SharhVazife更改为List而不是IEnumerable和所有bool? to bool，并且您可以添加{{1} }作为默认值。
