使用远程验证asp.net MVC

我喜欢尝试使用远程验证，我发现这个链接:http://www.youtube.com/watch?v=Ll8VtDRj8L4

我已经按照指令，它的工作，但问题是，当我试图从引用表中添加数据，验证不会工作

模型类: 

public partial class ms_student
{
    public int ID { get; set; }
    public string student_code{ get; set; }
    public virtual ms_person ms_person { get; set; }
}
public partial class ms_person
{
    public string name{ get; set; }
    public string email { get; set; }
    public virtual ms_student ms_student { get; set; }
}
元数据:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Web.Mvc;
namespace Test.Models
{
    [MetadataType(typeof(personMD))]
    public partial class ms_person
    {
    }
    public class personMD
    {
        [Required(ErrorMessage = "Email is required")]
        [EmailAddress(ErrorMessage = "Invalid Email Address")]
        [Remote("CheckEmailExist", "Administrator", ErrorMessage = "Email Already Exist")]
        public object email { get; set; }
    }
}

控制器:

public JsonResult CheckEmailExist(string email) // the error i think from email paramater, cause the video said to make the paramater exactly the same name...
{
    return Json(!db.ms_person.Any(m => m.email == email), JsonRequestBehavior.AllowGet);
}

视图:

@model Test.Models.ms_student
@using (Html.BeginForm("CreateStudent", "Administrator", FormMethod.Post,
                        new { enctype = "multipart/form-data" }))
{
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)
    @Html.TextBoxFor(model => model.student_code) //this one work and already tested
    @Html.ValidationMessageFor(model => model.student_code)
    @Html.TextBoxFor(model => model.ms_person.email) //if you inspect element on browser the NAME are ms_person.email and ID are ms_person_email
    @Html.ValidationMessageFor(model => model.ms_person.email)
}

我试图改变JsonResult控制器参数为(字符串ms_person.email)，但有错误说命名空间电子邮件找不到。还尝试使用(string ms_person_email)，也不工作

我也测试了使用student_code, student_code字段工作正常，因为student_code属性是在同一个模型(ms_student)，不像电子邮件(引用ms_person)

所有元数据验证工作，就像需要在两个模型上，所以我猜错误是在JsonResult参数

非常感谢

使用远程验证asp.net MVC

修改动作方法，使其包含Bind Prefix属性/属性

public JsonResult CheckEmailExist([Bind(Prefix="ms_person.email")]string email)
{
  ...

直接改成

@Html.TextBoxFor(model => model.ms_person.email, new{@id="email", @name="email"})
