C# ASP.NET MVC模型绑定器不绑定我的ViewModel

这是我的viewModel，我正在将其绑定到视图

public class EmployeeMasterViewModel
{
    public EmployeeViewModel Employee { get; set; }
    public List<SkillViewModel> Skills { get; set; }
}

提交表单时，计数为0

   @for (int i = 0; i < Model.Skills.Count; i++)
{
        SkillViewModel skill = Model.Skills[i];
        string id = skill.Id + "-" + String.Join("-", skill.SkillName.Split(new[] { " " },             StringSplitOptions.RemoveEmptyEntries));
        <tr id="@id">

            <td>
                @Html.HiddenFor(e => e.Skills[i].Id)
                @Html.HiddenFor(e => e.Skills[i].SkillName)
                @skill.SkillName
            </td>

            <td>
                <a href="javascript:deleteSkill('@id')">
                    <span class="label label-sm label-danger">
                        Delete
                    </span>
                </a>
            </td>
        </tr>

    }

我试图复制您的问题，但我的尝试效果良好

视图代码

控制器代码

当我提交表单时，所有数据都正确传递，包括技能数据。也许您可以使用此答案作为参考来帮助您？

您也可以发布您的操作方法吗？如果您的视图没有正确的@model语句，如果您的操作没有返回Viewmodel，则视图没有要绑定的Viewmodel。发布你的行动和观点。顺便说一句，当您定义一个模型时，它可以作为模型变量使用。技能从何而来？检查ModelState.IsValid和Errors集合以获取更多诊断信息。Mario-视图文件非常长Panagiotis Kanavos-当然，我也在view中定义了@model语句，GET操作也返回ViewMyEmployeeMasterViewModel我也用同样的方法做了，我有一个代码，它对其他业务实体运行良好，编写方式与前面提到的相同。实际上，我有一个与Skills同名的下拉列表，这与我的列表技能相冲突。是的，这是个愚蠢的错误

   @for (int i = 0; i < Model.Skills.Count; i++)
{
        SkillViewModel skill = Model.Skills[i];
        string id = skill.Id + "-" + String.Join("-", skill.SkillName.Split(new[] { " " },             StringSplitOptions.RemoveEmptyEntries));
        <tr id="@id">

            <td>
                @Html.HiddenFor(e => e.Skills[i].Id)
                @Html.HiddenFor(e => e.Skills[i].SkillName)
                @skill.SkillName
            </td>

            <td>
                <a href="javascript:deleteSkill('@id')">
                    <span class="label label-sm label-danger">
