FluentValidation NotEqual client side rule

Question

我正在尝试将不平等客户端规则添加到我的MVC 5项目中。

这一切似乎都在起作用，除了我似乎无法获取传递到规则中的错误消息。我可以在调试器的一个私有字段中看到它，我只是不确定如何在GetClientValidationRules方法中获得它。问题在构建错误消息的线上，validator.ErrorMessageSource.GetString()不再存在。

public class NotEqualClientRule : FluentValidationPropertyValidator 
{
  public static ModelValidator Create(ModelMetadata meta, ControllerContext context, PropertyRule propertyDescription, IPropertyValidator validator) 
  {
    return new NotEqualClientRule(meta, context, propertyDescription, validator);
  }
  public NotEqualClientRule(ModelMetadata metadata, ControllerContext controllerContext, PropertyRule propertyDescription, IPropertyValidator validator) : base(metadata, controllerContext, propertyDescription, validator) 
  {
    ShouldValidate = false; //This is necessary - don't want to kick in during model binding.
  }
  public override IEnumerable<ModelClientValidationRule> GetClientValidationRules() 
  {
    if (!this.ShouldGenerateClientSideRules()) 
    {
        yield break;
    }
    var validator = Validator as NotEqualValidator;
    var errorMessage = new MessageFormatter()
        .BuildMessage(validator.ErrorMessageSource.GetString());
    var rule = new ModelClientValidationRule 
    {
        ErrorMessage = errorMessage,
        ValidationType = "notequal"
    };
    if (validator.MemberToCompare != null) 
    {
        rule.ValidationParameters["field"] = String.Format("#{0}", validator.MemberToCompare.Name);
    } 
    else 
    {
        rule.ValidationParameters["field"] = validator.ValueToCompare;
    }
    yield return rule;
  }
}

更改

var errorMessage = new MessageFormatter().BuildMessage(validator.ErrorMessageSource.GetString());

to

var formatter = new MessageFormatter().AppendPropertyName(Rule.PropertyName);
string errorMessage = formatter.BuildMessage(validator.Options.ErrorMessageSource.GetString(null));

给我我在验证规则中设置的错误消息。
