asp.net-mvc – Route Id覆盖Model.Id

Conference/Committees/1

在该页面内,它循环通过会议委员会(会议ID = 1).

我有一个局部视图,为选定的委员会呈现一个编辑样式页面,其路径如下：

Conference/Committees/1?committeeId=2

在调试中,模型数据是正确的,委员会的Id = 2.但是,当我使用以下Razor语句时：

@Html.HiddenFor(model => model.Id)

使用以下型号：

@model munhq.Models.Committee

隐藏输入的值为“1”而不是“2”.

这是MVC中的错误吗？或者我做错了什么？

更新

如果我更换

@Html.HiddenFor(model => model.Id)

同

<input data-val="true" data-val-number="The field Id must be a number." data-val-required="The Id field is required." id="Id" name="Id" type="hidden" value="@Model.Id" />

它呈现正确的Id值.

            ViewBag.ConferenceId = id; // used for adding a committee member entry

                ViewBag.JsonAvailableMembers = jsonAvailableCommitteeMembers(id);
