c# - Asp.Net MVC 数据注释。如何在 2 个属性相等时获得客户端验证

Question

如何对两个属性进行客户端验证，例如经典密码确认密码场景。

我正在使用基于 EF 映射到我的数据库表的元数据类，代码如下。

我的类中注释掉的属性将使我得到服务器端验证，但不会得到客户端。

[MetadataType(typeof(MemberMD))]
public partial class Member
{

    //[CustomValidation(typeof(MemberMD), "Verify", ErrorMessage = "The password and confirmation password did not match.")]
    //[PropertiesMustMatch("Password", "ConfirmPassword", ErrorMessage = "The password and confirmation password did not match.")]
    public class MemberMD
    {           

        [Required(ErrorMessage = "Name is required.")]
        [StringLength(50, ErrorMessage = "No more than 50 characters")]
        public object Name { get; set; }

        [Required(ErrorMessage = "Email is required.")]
        [StringLength(50, ErrorMessage = "No more than 50 characters.")]
        [RegularExpression(".+\\@.+\\..+", ErrorMessage = "Valid email required e.g. abc@xyz.com")]
        public object Email { get; set; }


        [Required(ErrorMessage = "Password is required.")]
        [StringLength(30, ErrorMessage = "No more than 30 characters.")]
        [RegularExpression("[\\S]{6,}", ErrorMessage = "Must be at least 6 characters.")]
        public object Password { get; set; }

        [Required]
        public object ConfirmPassword { get; set; }

        [Range(0, 150), Required]
        public object Age { get; set; }


        [Required(ErrorMessage = "Postcode is required.")]
        [RegularExpression(@"^[a-zA-Z0-9 ]{1,10}$", ErrorMessage = "Postcode must be alphanumeric and no more than 10 characters in length")]
        public object Postcode { get; set; }

        [DisplayName("Security Question")]
        [Required]
        public object SecurityQuestion { get; set; }

        [DisplayName("Security Answer")]
        [Required]
        [StringLength(50, ErrorMessage = "No more than 50 characters.")]
        public object SecurityAnswer { get; set; }



        public static ValidationResult Verify(MemberMD t)
        {
            if (t.Password == t.ConfirmPassword)
                return ValidationResult.Success;
            else
                return new ValidationResult("");
        }
    }

任何帮助将不胜感激，因为我只做了 5 个月，请不要让我失望。

您只需将它放在您的 ConfirmPassword 属性中。

    [Compare("Password", ErrorMessage = "Passwords don't match.")]
    [Required]
    public object ConfirmPassword { get; set; }

这意味着它将比较您的 ConfirmPassword 属性和您的 Password 属性。
