剃刀视图中的嵌套循环取消组合我的radiobuttons

Question

我在正确渲染表单方面遇到了一些困难。在我看来，一个产品有几个Properties，每个属性都有几个Options可供选择，如果允许多个选项则使用复选框，如果不允许，则使用单选按钮。

这个剃刀代码：

@for (int i = 0; i < Model.Type.Properties.Count(); i++)
{
    <div class="col-lg-3 col-md-4 col-sm-6">
        <strong>@Model.Type.Properties[i].Label</strong><br />
        @if (Model.Type.Properties[i].AllowMultipleSelections)
        { // Multiple selections are allowed - we need checkboxes:
            @for (var j = 0; j < Model.Type.Properties[i].Options.Count(); j++)
            {
                @Html.HiddenFor(m => m.Type.Properties[i].Id)
                @Html.CheckBoxFor(m => m.Type.Properties[i].Options[j].Selected)
                @Html.LabelFor(m => m.Type.Properties[i].Options[j].Selected,
                    Model.Type.Properties[i].Options[j].StringValue)
                <br />
            }
        }
        else
        { // Multiple selections are NOT allowed - we need radio buttons:
            @for (var j = 0; j < Model.Type.Properties[i].Options.Count(); j++)
            {
                @Html.HiddenFor(m => m.Type.Properties[i].Id)
                @Html.RadioButtonFor(m => m.Type.Properties[i].Options[j].SelectedId,
                    Model.Type.Properties[i].Options[j].Id)
                @Html.LabelFor(m => m.Type.Properties[i].Options[j].Selected,
                    Model.Type.Properties[i].Options[j].StringValue)
                <br />
            }
        }
    </div>
}

...将呈现此HTML：

<div class="col-lg-3 col-md-4 col-sm-6">
    <strong>Size</strong>
    <br />
    <input id="Type_Properties_0__Id" 
            name="Type.Properties[0].Id" type="hidden" value="1" />
    <input id="Type_Properties_0__Options_0__SelectedId" 
            name="Type.Properties[0].Options[0].SelectedId" type="radio" value="1" />
    <label for="Type_Properties_0__Options_0__Selected">20-24</label>
    <br />
    <input id="Type_Properties_0__Id" 
            name="Type.Properties[0].Id" type="hidden" value="1" />
    <input id="Type_Properties_0__Options_1__SelectedId" 
            name="Type.Properties[0].Options[1].SelectedId" type="radio" value="2" />
    <label for="Type_Properties_0__Options_1__Selected">25-29</label>
    <br />
    <input id="Type_Properties_0__Id" 
            name="Type.Properties[0].Id" type="hidden" value="1" />
    <input id="Type_Properties_0__Options_2__SelectedId" 
            name="Type.Properties[0].Options[2].SelectedId" type="radio" value="3" />
    <label for="Type_Properties_0__Options_2__Selected">30-34</label>
    <br />
</div>
<div class="col-lg-3 col-md-4 col-sm-6">
    <strong>Suitable for</strong>
    <br />
    <input id="Type_Properties_3__Id" 
            name="Type.Properties[3].Id" type="hidden" value="1002" />
    <input id="Type_Properties_3__Options_0__Selected" 
            name="Type.Properties[3].Options[0].Selected" type="checkbox" value="true" />
    <label for="Type_Properties_3__Options_0__Selected">Women</label>
    <br />
    <input id="Type_Properties_3__Id" 
            name="Type.Properties[3].Id" type="hidden" value="1002" />
    <input id="Type_Properties_3__Options_1__Selected" 
            name="Type.Properties[3].Options[1].Selected" type="checkbox" value="true" />
    <label for="Type_Properties_3__Options_1__Selected">Men</label>
    <br />
</div>

问题在于，无线电按钮的id和name将获得唯一值（id="Type_Properties_{i}__Options_{j}__SelectedId" name="Type.Properties[{i}].Options[{j}].SelectedId"），从而“取消组合”它们。当然，这意味着当我只想选择一个时，我能够选择组中的所有单选按钮。我该如何解决这个问题？
