使用DataAnnotationsModelValidatorProvider.RegisterAdapter和默认客户端验证规则

Question

我需要使用资源来获取数据注释属性的错误消息 即时通过在global.asax

中注册DataAnnotationAdapter来实现此目的

这是我的适配器

public class ExternalResourceDataAnnotationsValidator : DataAnnotationsModelValidator<ValidationAttribute>
    {
        /// <summary>
        /// The type of the resource which holds the error messqages
        /// </summary>
        public static Type ResourceType { get; set; }

        /// <summary>
        /// Function to get the ErrorMessageResourceName from the Attribute
        /// </summary>
        public static Func<ValidationAttribute, string> ResourceNameFunc
        {
            get { return _resourceNameFunc; }
            set { _resourceNameFunc = value; }
        }
        private static Func<ValidationAttribute, string> _resourceNameFunc = attr => attr.GetType().Name;

        public ExternalResourceDataAnnotationsValidator(ModelMetadata metadata, ControllerContext context, ValidationAttribute attribute)
            : base(metadata, context, attribute)
        {   
            if (Attribute.ErrorMessageResourceType == null)
            {
                this.Attribute.ErrorMessageResourceType = ResourceType;
            }

            if (Attribute.ErrorMessageResourceName == null)
            {
                this.Attribute.ErrorMessageResourceName = ResourceNameFunc(this.Attribute);
            }

        }

    }

以下是我在global.asax

中注册的方式

ExternalResourceDataAnnotationsValidator.ResourceType = typeof(Resources);
DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(RequiredAttribute), typeof(ExternalResourceDataAnnotationsValidator));
DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(RangeAttribute), typeof(ExternalResourceDataAnnotationsValidator));
DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(MaxLengthAttribute), typeof(ExternalResourceDataAnnotationsValidator));

此代码不提供客户端验证，因为它不会返回任何客户端验证规则

我的问题是如何知道将ValidationType放入下面的方法

public override IEnumerable<ModelClientValidationRule> GetClientValidationRules()
        {
            var rm = new ResourceManager(ResourceType);
            var msg =rm.GetString(ResourceNameFunc(this.Attribute));
            return new[] {new ModelClientValidationRule() {ErrorMessage = msg, ValidationType ="??????"},};
        }
