不显眼的验证输入类型编号不起作用的最小/最大验证器

Question

我为输入类型编号设置了自定义验证器。我想将最小和最大长度都限制为16 ..我成功添加了自定义验证器，并在页面渲染时在输入字段上获取数据属性，但发现它没有验证字段。这是我的代码看起来像

[AttributeUsage(AttributeTargets.Property, AllowMultiple = true)]
    public class MaxDigitValidator : ValidationAttribute, IClientValidatable
    {
        private int _Max, _Min;

        public MaxDigitValidator(int max, int min, string errorMessage)
            : base(errorMessage)
        {
            _Max = max;
            _Min = min;
        }


        protected override ValidationResult IsValid(object value, ValidationContext validationContext)
        {
            ValidationResult validationResult = ValidationResult.Success;
            try
            {

                if (!IsValid(value))
                {

                    validationResult = new ValidationResult(ErrorMessageString);
                }
                else
                {
                    validationResult = new ValidationResult("An error occurred while validating the property. OtherProperty is not of type DateTime");
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }

            return validationResult;
        }


        public override bool IsValid(object value)
        {
            if (value is int)
            {
                var stringValue = "" + (int)value;
                var length = stringValue.Length;
                if (length >= _Min && length <= _Max)
                {
                    return true;
                }
            }
            return false;
        }

        public IEnumerable<ModelClientValidationRule> GetClientValidationRules
            (ModelMetadata metadata, ControllerContext context)
        {
            var errorMessage = ErrorMessageString;
            var maxDigitRule = new ModelClientValidationRule();
            maxDigitRule.ErrorMessage = errorMessage;
            maxDigitRule.ValidationType = "maxdigit";
            maxDigitRule.ValidationParameters.Add("max", _Max);
            maxDigitRule.ValidationParameters.Add("min", _Min);

            yield return maxDigitRule;
        }
    }

为了启用客户端验证，我添加了一个不显眼的适配器

$(function () {
    $.validator.addMethod("maxdigits", function (value, element, param) {
        if (!value) return false;

        console.log(param.min);
        return false;
    });

    $.validator.unobtrusive.adapters.addMinMax("maxdigit", "maxdigits", "maxdigits", "maxdigits");

});

任何建议请
