C# 使用远程验证asp.net MVC

我想尝试使用我在该链接上发现的远程验证：

我已经按照说明进行了操作，但问题是，当我尝试从引用表中添加数据时，验证不起作用

型号类别：

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; }
}

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);
}

@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)
}

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 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; }
}

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);
}

@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)
}

视图：

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; }
}

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);
}

@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)
}

我曾尝试将JsonResult控制器参数更改为（字符串ms_person.email），但错误是找不到命名空间电子邮件。。也尝试过使用（字符串ms_person_email），也不会起作用

我还使用student_代码进行了测试，student_代码字段工作正常，因为student_代码属性在同一个模型中（ms_student），而不像电子邮件（参考ms_person）

所有的元数据验证工作，比如两个模型都需要，所以我猜错误在JsonResult参数上

非常感谢

只需将其更改为

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

更改操作方法以包括

绑定前缀

属性/属性

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

---

您可以尝试

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

尝试一下，但不起作用：O，现在正在搜索另一个解决方案..刚刚测试过，它应该是

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

很好，我想您失踪了”）”就在“]”之前，itu应该是JsonResult CheckEmailExist（[Bind（Prefix=“ms_person.email”）]string email）Thx：当然（笨拙的手指）。我将作为答案发布。这不会更改名称。Html帮助程序覆盖任何设置

名称

属性`的尝试，只是询问我是否使用新的{}更改名称和id，这是否意味着实体框架将无法识别id和名称，电子邮件也不会插入数据库？只是好奇…还没有尝试。。。
