/// <summary> /// 用户邮箱 /// </summary> [DisplayName("邮箱")] //[DataType(DataType.EmailAddress)] [RegularExpression(@"^\w+((-\w+)|(\.\w+))*\@[A-Za-z0-9]+((\.|-)[A-Za-z0-9]+)*\.[A-Za-z0-9]+$", ErrorMessage = "电子邮件格式错误")] public string Email { get; set; }
第一个参数邮箱验证的正则表达式，第二个参数是错误提示信息。
在ASPX页面显示错误信息用<%:Html.ValidationMessageFor(m=>m.Email)%>
以上是对用户注册信息的验证，当然，我们在提交信息的时候，要判断验证是否通过，我们使用ModelState.IsValid来判断验证是否通过，TRUE表示通过，FALSE表示未通过。
model代码：
/// <summary> /// 注册用户MODEL /// </summary> [PwdMatch("UserPwd", "ConfirPwd", ErrorMessage = "密码与确认不匹配")] public class RegisterModel { /// <summary> /// 用户名 /// </summary> [DisplayName("用户名")] [Required(ErrorMessage="用户名不能为空!")] public string UserName { get; set; } /// <summary> /// 密码 /// </summary> [DisplayName("密码")] [Required(ErrorMessage="密码不能为空")] [StringLength(10, ErrorMessage = "密码长度不能小于5位",MinimumLength=5)] public string UserPwd { get; set; } [DisplayName("确认密码")] [Required(ErrorMessage="确认密码不能为空!")] [StringLength(10, ErrorMessage = "确认密码长度不能小于5位",MinimumLength=5)] public string ConfirPwd { get; set; } /// <summary> /// 用户邮箱 /// </summary> [DisplayName("邮箱")] //[DataType(DataType.EmailAddress)] [RegularExpression(@"^\w+((-\w+)|(\.\w+))*\@[A-Za-z0-9]+((\.|-)[A-Za-z0-9]+)*\.[A-Za-z0-9]+$", ErrorMessage = "电子邮件格式错误")] public string Email { get; set; } } /// <summary> /// 此自定义类用于验证密码和确认密码必须一致 /// </summary> [AttributeUsage(AttributeTargets.Class, AllowMultiple = true, Inherited = true)] public class PwdMatch :ValidationAttribute { private object _typeid = new object(); public string PWD { get; set; }//密码 public string ConfirmPwd { get; set; }//确认密码 public PwdMatch(string pwd, string confirmPwd) : base() { PWD = pwd; ConfirmPwd = confirmPwd; } /// <summary> /// 返回错误的提示信息 /// </summary> /// <param></param> /// <returns></returns> public override string FormatErrorMessage(string name) { return ErrorMessage; } /// <summary> /// 重写TYPEID /// </summary> public override object TypeId { get { return _typeid; } } /// <summary> /// 判断是否想到 /// </summary> /// <param>value的值实际上是MODEL提交的MODEL类</param> /// <returns></returns> public override bool IsValid(object value) { PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(value); object originalValue = properties.Find(PWD, true ).GetValue(value);//获取密码 object confirmValue = properties.Find(ConfirmPwd, true).GetValue(value);//获取确认密码的值 return Object.Equals(originalValue, confirmValue); } }
