If you are using pattern "^[a-zA-Z0-9-.]+@[a-zA-Z0-9-.]+$" please

replace your pattern "^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$"

**it will work properly.**

```
@model ForumMVC.Models.Customer
@{    ViewBag.Title = "CheckRegularExpression";
}
<script src="~/Scripts/jquery-2.1.4.js"></script>
<script src="~/Scripts/jquery.validate.min.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.js"></script>
<h2>CheckRegularExpression</h2>
@using (Html.BeginForm())
{       @Html.LabelFor(m => m.EmailId)
    @Html.TextBoxFor(m => m.EmailId)
    @Html.ValidationMessageFor(m => m.EmailId)
}
```

\

```
using System;using System.Collections.Generic;using System.Linq;using System.Linq.Expressions;using System.Web;using System.ComponentModel.DataAnnotations;namespace ForumMVC.Models{    public class Customer    {        [RegularExpression(@"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$",         ErrorMessage = "Please enter a valid e-mail-2 adress")]        public string EmailId        {
            get;
            set;
        }

    }
}
```
