当我提交 Ajax.BeginForm 表单时，我在 Controller 上得到了 Model 的 null 值。模型内部有另一个模型（一对多关系）
这是我的示例视图代码（删除了不必要的东西）
<table id="PageSortTable" class="travelads_business_rules" cellspacing="0">
<thead>
<tr valign="bottom">
<th>ID</th>
<th> </th>
<th> </th>
<th>Rule Name</th>
<th>Business</th>
<th>Region</th>
<th>Form</th>
<th>Company</th>
<th>Team</th>
<th>Language</th>
<th>Media</th>
<th>InsertLoc</th>
<th>Size</th>
<th>Access</th>
</tr>
</thead>
<tbody>
@foreach (var item in Model)

这是我的控制器操作
[Authorize]
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult _SaveGroupMatchs(FormCollection fc, TravelAdsRulesMatchsGroups trmg)
{
// trmg is null here... I am getting form collection but its comma separated, very annoying to deal with that.
}
任何人都可以有想法，我如何获得模型值。
这是我的班级信息
主类 TravelAds - 需要显示邮件记录（网格）
TravelAdsRulesMatchsGroups - 表内的第一个 foreach 循环类
MatchCollection - TravelAdsRulesMatchsGroups 中的第二个 foreach 循环类
我试图在控制器中获取带有值和子类（匹配集合）的 TravelAdsRulesMatchsGroups 对象，我认为无论如何都应该有。
