我正在实现IValidatableObject。在我的Validate函数中，我希望返回多个ValidationResults。如何实现这一点最好？

public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
        {

            List<ValidationResult> validationResults = new List<ValidationResult>();

            if (QuantityTraded < 1 || QuantityTraded > MaxTradeQuantity )
            {
                validationResults.Add(new ValidationResult($"There must be a quantity greater than zero and less than {MaxTradeQuantity}"));
            }
            if (TotalAmount > TotalPortfolioCash)
            {
                validationResults.Add(new ValidationResult($"There is currently not enough money in the Portfolio ({TotalPortfolioCash}) for this order."));
            }

            if(validationResults.Any() && validationResults.Count > 0)
            {
                return validationResults;
            } 
        }

这似乎不是一个好方法，因为如果没有ValidationResults，它就不应该返回任何东西。如果我回到使用yield，

yield return new ValidationResult($"There is currently not enough money in the Portfolio ({TotalPortfolioCash}) for this order.");

我一次只能返回一个ValidationResult，而不是多个。有没有更好的方法来处理这个问题？
