c# - FluentValidation DI 将值传递给子验证器

Question

我最近发现了 FluentValidator 并开始研究依赖注入(inject)。我似乎无法弄清楚如何使用当前的 DI 设置将值传递给子验证器。

我想从 InvoiceDetailsValidator 访问 Invoice.InvoiceNumber。

public class InvoiceValidator : AbstractValidator<Invoice>
{
    private readonly IDbContextFactory<DbContext> dbContextFactory;

    public InvoiceValidator(InvoiceDetailsValidator invoiceDetailsValidator, IDbContextFactory<DbContext> dbContextFactory)
    {
        ...

        RuleFor(x => x.InvoiceNumber)
            .Must(BeSomething)
            .WithMessage("Invoice number is required.");

        RuleForEach(x => x.InvoiceDetails)
            .SetValidator(invoiceDetailsValidator);
    }
}

public class InvoiceDetailsValidator : AbstractValidator<InvoiceDetails>
{
    public InvoiceDetailsValidator(IDbContextFactory<DbContext> dbContextFactory)
    {
        ...

        RuleFor(x => x.InvoiceSection)
            .NotEmpty()
            .When(X => !string.IsNullOrEmpty( /* InvoiceNumber? */ ))
            .WithMessage("Invoice section is required.");
    }
}

如有任何帮助，我们将不胜感激。

从

更改 Paarent 验证器构造函数

    public InvoiceValidator(InvoiceDetailsValidator invoiceDetailsValidator, 
                            IDbContextFactory<DbContext> dbContextFactory
                           )

到

    public InvoiceValidator(IValidator<InvoiceDetails> invoiceDetailsValidator, 
                            IDbContextFactory<DbContext> dbContextFactory
                           )
