使用 ASP.NET MVC 数据类型属性的电子邮件地址验证 [英] Email address validation using ASP.NET MVC data type attributes

问题描述

我在验证电子邮件时遇到一些问题.

I have some problems with the validation of a Email.

在我的模型中:

[Required(ErrorMessage = "Field can't be empty")]
[DataType(DataType.EmailAddress, ErrorMessage = "E-mail is not valid")]
public string ReceiverMail { get; set; }

在我看来:

<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>

@Html.TextBoxFor(m => m.ReceiverMail, new { @placeholder="E-mail"}) <br />
@Html.ValidationMessageFor(m => m.ReceiverMail)

现在，当您将字段留空时，它会正确地向我显示字段不能为空".但是，当您填写无效的电子邮件地址时，例如:fwenrjfw"，则表单不会显示电子邮件无效".

Now it is correctly showing me "Field can't be empty" when you leave the field empty. But when you fill in an invalid email address like: "fwenrjfw" then the form does not say "E-mail is not valid".

如何获取表单以将输入验证为电子邮件地址?我正在寻找这方面的帮助.

How can I get the form to validate the input as an email address? I am looking for some help with this.

推荐答案

如果您使用 .NET Framework 4.5，解决方案是使用位于 System.ComponentModel.DataAnnotations 中的 EmailAddressAttribute.

If you are using .NET Framework 4.5, the solution is to use EmailAddressAttribute which resides inside System.ComponentModel.DataAnnotations.

您的代码应该类似于:

[Display(Name = "Email address")]
[Required(ErrorMessage = "The email address is required")]
[EmailAddress(ErrorMessage = "Invalid Email Address")]
public string Email { get; set; }
