  • MVC4数据注解和验证

    model中的验证注解特性:

    public class StuInfo
        {
            public int ID { get; set;}
     
            [Display(Name = "姓名")]    //设置要显示的字段名
            [Required(ErrorMessage = "您需要填写{0}")]  //设置为必须字段 已经错误提示
            [StringLength(50, MinimumLength = 3)]     //设置最大长度和最小长度
            public string Name { get; set;}
     
            [Display(Name = "年龄")]
            [Range(1, 150, ErrorMessage = "年龄填写不正确!")]  //设置 值范围
            public int Age { get; set;}
     
            [Display(Name = "身高")]
            [Range(typeof(decimal),"50.00", "250.00",ErrorMessage = "身高超出指定范围")]
            public decimal Height { get; set;}
     
            [Display(Name = "生日")]
            [DataType(DataType.Date,ErrorMessage = "{0}格式不正确")]  //设置数据类型以及错误提示
            public DateTime Birthday { get; set;}
     
            [Display(Name = "电话")]
            [Remote("CheckPhone","StuInfo", ErrorMessage = "{0}已被注册")]   //在指定的Conteroller中的通道(route)中验证数据
            public string Phone { get; set;}
     
            [Display(Name = "地址")]
            [DataType(DataType.MultilineText)]
            public string Address { get; set;}
     
            [Display(Name = "电子邮箱")]
            [RegularExpression(@"(w)+(.w+)*@(w)+((.w+)+)",ErrorMessage = "{0}格式不正确")]  //正则验证
            public string Email { get; set;}
     
            [Display(Name = "再次输入电子邮箱")]
            [Compare("Email",ErrorMessage = "{0}两次输入不一致")]   //设置比较两个字段的值
            public string EmailConfirm { get; set;}
     
            [Display(Name = "密码")]
            [DataType(DataType.Password)]
            public string Password { get; set;}
     
            [Display(Name = "备用电子邮箱")]
            [DataType(DataType.EmailAddress,ErrorMessage = "{0}格式不正确")]
            public string email_B { get; set;}
    }

    远程验证的通道:

    public JsonResult CheckPhone(string phone)
                  {
                    var result= StuInfoBll.FindPhone(phone).count == 0;
                    return Json(result, JsonRequestBehavior.AllowGet);
              }

    效果:
