C# 将模型错误消息添加到具有部分视图的唯一索引

我有一个由部分视图创建的模型列表，所以每一行都有一个唯一id的索引

我想在此表单的帖子中向列表中的字段添加模型错误。但是控制器中没有唯一的id，因此，我无法将验证消息的键指定给字段

有人能帮忙吗

更新代码：

用表单查看

using (Html.BeginForm("Socio", "Student", FormMethod.Post, new { enctype = "multipart/form-data" ,@class= "SpForm" }))
{
    @Html.AntiForgeryToken()
 <div id="Studfindiv">
            @foreach (var StudFin in Model.ListStudentFinances)
            {
                @Html.Partial("StudFinView", StudFin)
            }
        </div>

}

使用（Html.BeginForm（“social”、“Student”、FormMethod.Post、new{enctype=“multipart/formdata”、@class=“SpForm”}））
{
@Html.AntiForgeryToken（）
@foreach（Model.ListStudentFinances中的var StudFin）
{
@Html.Partial（“StudFinView”，StudFin）
}
}

包含以下验证消息的局部视图：

@using HtmlHelpers.BeginCollectionItem
@model DataEntities.StudentFinance

    <div class="studfin">
        @using (Html.BeginCollectionItem("ListStudentFinances"))
        {
            <div class="text-center">

有人能帮我添加验证消息吗？
你能添加一些代码以便更好地解释吗？我们都会从中受益！我已经添加了验证消息，你能帮我吗？
