维护ASP.NET MVC中动态的复选框列表的状态

@foreach (var item in Model.CheckBoxList)
{
    <div>
        @Html.CheckBoxFor(m => item.IsSelected, new { id = "chk_" + item.Id, name = "chk_" + item.Id })
        @Html.Label("chk_" + item.Id, item.Name)
    </div>
}

[HttpPost]
public ActionResult Index(FormCollection form)
{
    foreach (var item in Model.CheckBoxList)
    {
        item.IsSelected = form["chk_" + item.Id] != null;
    }

    // 其他处理逻辑

    return View();
}

@foreach (var item in Model.CheckBoxList)
{
    <div>
        @Html.CheckBoxFor(m => item.IsSelected, new { id = "chk_" + item.Id, name = "chk_" + item.Id, @checked = item.IsSelected })
        @Html.Label("chk_" + item.Id, item.Name)
    </div>
}
