如何为具有相同名称的多个输入添加验证？

Question

帐户模型类别：

 [Table("Accounts")]
    public class Account
    {
        public int Id { get; set; }
        public string CompanyName { get; set; }
        public float Interval { get; set; }
    }

移动模型类：

public class Mobile
{

    public int Id { get; set; }
    public string MobileNo { get; set; }
    public virtual Account Account { get; set; }

    public static Mobile Add(string mobile)
    {
        Mobile mobiles = new Mobile();
        mobiles.MobileNo = mobile;

        return mobiles;
    }
}

 @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        <div class="form-group row">
            @Html.LabelFor(model => model.Name, htmlAttributes: new { @class = "col-sm-2 col-md-1 col-form-label" })
            <div class="col-sm-10 col-md-3">

在这里，我为 移动 输入了3个输入字段。我可以为 名称 或 时间间隔 添加验证规则。但是如何为 移动 添加验证规则。即：我想检查手机号码的唯一性，并且前两个输入字段包含唯一的手机号码，其中第二个输入字段包含重复的手机号码。因此，对于第三个输入字段的验证失败。有想法吗？
