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

Your code should look similar to this:

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

blocks|key|94793|text|尝试使用Html.EditorFor帮助器方法而不是Html.TextBoxFor。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|94794|entityMap^0|4|E|Q|F|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

Try <code>Html.EditorFor</code> helper method instead of <code>Html.TextBoxFor</code>.

blocks|key|94757|text|您需要使用RegularExpression属性，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|94758|[RegularExpression("%5E[a-zA-Z0-9_\\.-]%2B@([a-zA-Z0-9-]%2B\\.)%2B[a-zA-Z]{2,6}$",+ErrorMessage+=+"E-mail+is+not+valid")]|code-block|syntax|javascript|94759|并且不要删除[Required]，因为[RegularExpression]不会影响空字段。|offset|length|style|CODE|94760|entityMap^0|0|0|6|A|J|J|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]|$I|T|J|U|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|N|$]]

You need to use RegularExpression attribute, something like this:
<pre><code>[RegularExpression(&quot;^[a-zA-Z0-9_\\.-]+@([a-zA-Z0-9-]+\\.)+[a-zA-Z]{2,6}$&quot;, ErrorMessage = &quot;E-mail is not valid&quot;)]
</code></pre>
And don't delete <code>[Required]</code> because <code>[RegularExpression]</code> doesn't affect empty fields.

if you aren't yet using .net 4.5:

<pre><code>/// &lt;summary&gt;

/// &lt;/summary&gt;

 }

 /// &lt;summary&gt;
 /// from: http://stackoverflow.com/a/6893571/984463

 public override string FormatErrorMessage(string name)

[Email(ErrorMessage+=+"The+email+address+is+not+valid")]

I use MVC 3. An example of email address property in one of my classes is:

<pre><code>[Display(Name = "Email address")]
[Required(ErrorMessage = "The email address is required")]
[Email(ErrorMessage = "The email address is not valid")]
public string Email { get; set; }
</code></pre>

Remove the <code>Required</code> if the input is optional. No need for regular expressions although I have one which covers all of the options within an email address up to RFC 2822 level (it's very long).

Used the above code in MVC5 project and it works completely fine with

blocks|key|94941|text|脚本通常加载在html页面的末尾，MVC建议使用bundle。因此，我最好的假设是，您的jquery.validate文件在某种程度上被更改了，或者没有更新到最新版本，因为它们确实会验证电子邮件输入。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|94942|所以你可以更新/刷新你的nuget包，或者编写你自己的函数。|94943|下面是一个示例，您可以在jquery.validate.unobtrusive之后添加一个额外的文件|94944|$.validator.addMethod(

);|code-block|syntax|javascript|94945|这只是对当前jquery.validate正则表达式的复制和粘贴，但通过这种方式，您可以设置自定义错误消息/向字段添加额外的方法，以便在不久的将来进行验证。|94946|entityMap^0|18|F|0|0|C|R|0|0|6|F|0^^$0|@$1|2|3|4|5|6|7|S|8|@$9|T|A|U|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|V|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|W|8|@$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|J|3|K|5|L|7|Z|8|@]|D|@]|E|$M|N]]|$1|O|3|P|5|6|7|10|8|@$9|11|A|12|B|C]]|D|@]|E|$]]|$1|Q|3|-4|5|6|7|13|8|@]|D|@]|E|$]]]|R|$]]

Scripts are usually loaded in the end of the html page, and MVC recommends the using of bundles, just saying. So my best bet is that your <code>jquery.validate</code> files got altered in some way or are not updated to the latest version, since they do validate e-mail inputs.

So you could either update/refresh your nuget package or write your own function, really.

Here's an example which you would add in an extra file after <code>jquery.validate.unobtrusive</code>:

<pre><code>$.validator.addMethod(
 "email",
 function (value, element) {
 return this.optional( element ) || /^[a-zA-Z0-9.!#$%&amp;'*+\/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$/.test( value );
 },
 "This e-mail is not valid"
);
</code></pre>

This is just a copy and paste of the current <code>jquery.validate</code> Regex, but this way you could set your custom error message/add extra methods to fields you might want to validate in the near future.

<pre><code>[RegularExpression(@&quot;^[A-Za-z0-9]+@([a-zA-Z]+\\.)+[a-zA-Z]{2,6}]&amp;&quot;)]
</code></pre>

I have some problems with the validation of a Email.

In my Model:

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

In my view:

<pre><code>&lt;script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"&gt;&lt;/script&gt;
&lt;script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"&gt;&lt;/script&gt;

@Html.TextBoxFor(m =&gt; m.ReceiverMail, new { @placeholder="E-mail"}) &lt;br /&gt;
@Html.ValidationMessageFor(m =&gt; m.ReceiverMail)
</code></pre>

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".

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