在 Fluentvalidation 中使用 SetValidator 验证通用集合

Question

我正在尝试验证通用类型：

public class Request<T> where T : class
{
    public int Test { get; set; }

    public List<T> Records { get; set; } = [];
}

如何设置

SetValidator

？我遇到错误：

Cannot convert from ‘QuotasValidator’ to ‘FluentValidation.Validators.IPropertyValidator<Request<T>, T>’

。我也试过

RuleForEach(request => request.Records.OfType<Quotas>()).SetValidator(new QuotasValidator());

public class RequestValidator<T> : AbstractValidator<Request<T>> where T : class
{
    public RequestValidator()
    {
        //if (T is typeOf(..))
            RuleForEach(request => request.Records).SetValidator<T>(new QuotasValidator());
    }
}

是否有可用的现成解决方案，或者我是否需要实施自定义解决方案？我查看了多态验证器。也许我缺少一种方法？

Answer 1

我最终使用了多态验证器：

public interface IRequest<T>
{
    public List<T> Records { get; set; }
}

public class QuotaRequest : IRequest<Item>
{
    public List<Item> Records { get; set; } = [];
}

public class RequestValidator : AbstractValidator<QuotaRequest>
{
    public RequestValidator()
    {
        RuleForEach(request => request.Records).SetValidator(new ItemValidator());
    }
}
