update the navigate of a Model(Be careful!)

@for (var int i = 0; i < Model.Rates; i++)
{
    <tr>
        <td>
            @Html.EditorFor(modelItem => Model.Rates[i].minCount)
            @Html.ValidationMessageFor(model => Model.Rates[i].minCount)
        </td>
        <td>
            @Html.EditorFor(modelItem => Model.Rates[i].maxCount)
            @Html.ValidationMessageFor(model => Model.Rates[i].maxCount)
        </td>
        <td>
            @Html.EditorFor(modelItem => Model.Rates[i].Amount)
            @Html.ValidationMessageFor(model => Model.Rates[i].Amount)
        </td>
    </tr>
}

记住要用for形式写成Model.Rates[i].minCount 的形式才能使 Name属性正常并绑定上Model,如果用foreach每个导航属性形成的 Name属性都是一样的。
