我在表格的每一行都有@Ajax.BeginForm，当我使用该表格发出发布请求时，除第一行外，模型为空。

只有第一个表格有效，第二个表格无效......我使用了唯一的表格ID。

可能是因为我使用的是 IList 和 for 循环，

AND 第一个表单具有控件名称，如 [0].lstMatches[4].match_set_name 和第二、第三、....表单具有控件名称，如 [n].lstMatches[4].match_set_name

并且 IList 只能为第一个提供模型，[0].lstMatches[4].match_set_name

这是我的视图结构

  @model IList<QIOnlineMVC3.Models.TravelAdsRulesMatchsGroups>
@{
ViewBag.Title = "Business Rule Travel Ads";
ViewBag.Layout = "_Layout2";
 }

这是我的控制器

    [Authorize]

    public ActionResult _SaveGroupMatchs(IList<TravelAdsRulesMatchsGroups> mm)
    {
        try
        {
            if (mm != null & mm.Count > 0)
            {

                foreach (var item in mm)
                {
                    List<MatchModel> LMM = item.lstMatches.ToList();
                    List<MatchModel> LMMUpdate = LMM.Where(t => t.match_id != 0).ToList();
                    //update 
                    foreach (var mmupdate in LMMUpdate)
                    {
                        UpdateMatch(mmupdate);
                    }
                    List<MatchModel> LMMSave = LMM.Where(t => t.match_id == 0).ToList();
                    //save
                    foreach (var itemSave in LMMSave)
                    {
                        itemSave.access = item.access;
                        itemSave.deployment = item.deployment;
                        itemSave.match_deployment = item.deployment;
                        CreateMatch(itemSave);
                    }
                }
            }
        }
        catch { Content("Problem due to Error"); }

        return Content("Record Saved Successfully!");
    }

我没有得到第二个 IList 等行......

我怎样才能得到它，有什么想法吗？

嗯，我真的不明白你想做什么。

  • 如果您想保存TravelAdsRulesMatchsGroups
    仅使用一个调用您的_SaveGroupMatchs操作方法 的表单的 wole 列表

  • 如果您只想保存一个TravelAdsRulesMatchsGroups（每条记录一个提交按钮），
    请继续每行使用一个form并将控制器的操作更改为 

    public ActionResult _SaveGroupMatchs(TravelAdsRulesMatchsGroups mm)

    然后调整你的动作方法来处理一个实例的记录TravelAdsRulesMatchsGroups

    而且，在您的视图中，不要使用 

    @Html.HiddenFor(model => model[i].Id)

    如果您使用此语法，则呈现的 Html 将是<input ... name="[i].Id" />
    （例如。<input ... name="[2].Id" />）

    模型绑定器使用name来填充模型的属性

    相反，使用

    @* for your TravelAdsRulesMatchsGroups properties *@
@Html.Hidden("id", Model[i].id)
@* ... and so on ...*@


@* for the lstMatches property, which is a list of MatchModel *@
@for (var j = 0; j < Model[i].lstMatches.Count; j++)
{
    @Html.Hidden("lstMatches[" + j.ToString() + "].match_rule_id", Model[i].lstMatches[j].match_rule_id)
    @* ... and so on ...*@
}

注意：小心，您不能使用嵌套的 Html 表单！
