“值 'emailaddress' 无效” 验证在 asp.net mvc 中失败

Question

我正在开发一个应用程序，我有一个表单，其中每个文本框都有验证。我已经包含了自定义验证语句。它们工作得更好。但是我有一个文本框的电子邮件地址数据类型。但是当我提交表单时，我遇到错误“'emailaddress' 的值无效”..请查看我的代码，如果有任何问题，请告诉我.. 我的模型类是

[Table("email")]
   public  class eMail
    {
       [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
       public int ID { get; set; }

       [Required(ErrorMessage="The Name is Required")]
       [StringLength(20,ErrorMessage="The maximum length of the name should be 20 Characters")]
       [Display(Name="Your Name")]
       public string Name { get; set; }

       [Required(ErrorMessage = "Email is required")]
       [EmailAddress(ErrorMessage = "Enter a proper email address")]
       [StringLength(25, ErrorMessage = "Maximum length allowed for an email is 30 characters")]
       public string Email { get; set; }

       [Required(ErrorMessage="Please print your request")]
       [StringLength(200,ErrorMessage="Maximum Characters allowed Are 200")]
       [Display(Name="Prayer Request")]
       [DataType(DataType.MultilineText)]
       public string Request{get;set;}
    }

我的控制器是：

using CTCFremont.Models;
using System;
using System.Collections.Generic;
using System.Data.Entity;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace CTCFremont.Controllers
{
    public class eMailController : Controller
    {
        private CTCFremontEntities db = new CTCFremontEntities();

        //
        // GET: /eMail/

        public ViewResult Index()
        {
            return View();
        }



        public ActionResult Create()
        {
            return View();
        }

        //
        // POST: /eMail/Create

        [HttpPost]
        public ActionResult Create(eMail email)
        {
            if (ModelState.IsValid)
            {
                db.eMails.Add(email);
                db.SaveChanges();
                return RedirectToAction("Index");
            }

            return View(email);
        }

        //
        // GET: /eMail/Edit/5


        protected override void Dispose(bool disposing)
        {
            db.Dispose();
            base.Dispose(disposing);
        }
    }
}

我的看法是：

@model CTCFremont.Models.eMail

@{
    ViewBag.Title = "Create";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
<script src="https://code.jquery.com/jquery-2.1.4.js"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
<style type="text/css">
#RequestForm {
    position:absolute;
    top: 50%;
    left: 25%;
    width:30em;
    height:18em;
    margin-top: -9em; /*set to a negative number 1/2 of your height*/
    margin-left: -15em; /*set to a negative number 1/2 of your width*/
    border: 1px solid #ccc;
}
    div.request {
       box-shadow: 10px 10px 5px #888888
    }

</style>

<h2>Submit Your Prayer Request</h2>
@using (Html.BeginForm()) {
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)  
        <div id="#Actual" style ="background-image:url('../../Images1/pray.jpg')">
        <div class="request" id="RequestForm" style="width:1000px">
            <div class="container">
            <div class="editor-label">

            @Html.LabelFor(model => model.Name)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.Name)
            @Html.ValidationMessageFor(model => model.Name)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Email)
        </div>
        <div class="text-field">
            @Html.EditorFor(model => model.Email)
            @Html.ValidationMessageFor(model => model.Email)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.Request)
        </div>
        <div class="editor-field"  >
            @Html.TextAreaFor(model => model.Request,new { style = "width:400px ",maxlength = 200 })
            @Html.ValidationMessageFor(model => model.Request)
        </div>
          <p>
            <input type="submit" value="Create" />
        </p>
        </div>     
        </div>    
        </div>

}


@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

我的桌子是：

CREATE TABLE [dbo].[eMail] (
    [ID]      INT            IDENTITY (1, 1) NOT NULL,
    [Name]    NVARCHAR (20)  NOT NULL,
    [Email]   NVARCHAR (25)  NOT NULL,
    [Request] NVARCHAR (200) NOT NULL,
    PRIMARY KEY CLUSTERED ([ID] ASC)
);

我相信原因是 MVC 模型绑定器在您的电子邮件模型类和该类的电子邮件属性之间混淆了。

您可以通过在 ModelState.IsValid 上设置断点来验证这一点，并验证 ModelState.Errors 对象以查看发生了什么问题。

另外，您能否尝试在您引用它的任何地方将您的 Email 属性重命名为 Email1，并添加 Column 属性以使其与您的表同步。

类似这样的尝试：

[Column("Email")]
        [Required]
        [EmailAddress(ErrorMessage = "Enter a proper email address")]
        [StringLength(25, ErrorMessage = "Maximum length allowed for an email is 30 characters")]
        public string Email1 { get; set; }
