一、定义

---

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel.DataAnnotations;

namespace HJ.BaseMetadata
{
    /// <summary>
    /// 邮箱验证类
    /// </summary>
   public class EmailAttribute :RegularExpressionAttribute
    {
       //验证邮箱
       public EmailAttribute():base(@"^w+([-+.]w+)*@w+([-.]w+)*.w+([-.]w+)*$")
       {

       }
    }
}

 

二、调用

[Email(ErrorMessage="邮箱格式不正确")))]
        public string Email { get; set; }
