public class ParentClass
{
    public int ParentId { get; set; }
    public int ActivityId { get; set; }
    public DateTime UpateDate { get; set; }
    public IList<ChildClass> ChildList { get; set; }

public class ParentClassValidator : AbstractValidator<ParentClass>
{
    public ParentClassValidator()
    {
        RuleFor(x => x.ParentId).NotEmpty().WithMessage("Parent Id cannot be empty");
        When(x => x.ParentId == 1, () =>
          {
              RuleFor(x => x.ActivityId).NotEmpty().WithMessage("Activity To cannot be empty.");
              RuleFor(x => x.ChildList).SetCollectionValidator(new ChildClassValidator().Validate(new ChildClass(), "ParentId1"));
          });
    }
}

public class ChildClass
{
    public int ChildId { get; set; }
    public DateTime DueDate { get; set; }

}

public class ChildClassValidator : AbstractValidator<ChildClass>
{
    public ChildClassValidator()
    {
        RuleFor(x => x.ChildId).NotEmpty().WithMessage("Child Id cannot be empty");
        RuleSet("ParentId1", () =>
        {
            RuleFor(x => x.DueDate).Must(date => date != default(DateTime)).WithMessage("Due date cannot be empty");
        });
    }
}

我正在尝试根据父模型属性值验证子列表。

我需要验证来自父级的所有子级的通用规则以及特定规则集。我在父验证程序中尝试了以下代码RuleFor(x => x.ChildList).SetCollectionValidator(new ChildClassValidator().Validate(new ChildClass(), "ParentId1"));，但不允许

我经历了Child Model Validation using Parent Model Values. Fluent Validation. MVC4，但它只适用于一个属性。

[Validator(typeof(ParentClassValidator))]
public class ParentClass
{
    public int ParentId { get; set; }
    public int ActivityId { get; set; }
    public DateTime UpateDate { get; set; }
    public IList<ChildClass> ChildList { get; set; }
}

public class ParentClassValidator : AbstractValidator<ParentClass>
{
    public ParentClassValidator()
    {
        RuleFor(x => x.ParentId).NotEmpty().WithMessage("Parent Id cannot be empty");
        When(x => x.ParentId == 1, () =>
        {
              RuleFor(x => x.ActivityId).NotEmpty().WithMessage("Activity To cannot be empty.");
        });
    }

    public override ValidationResult Validate(ValidationContext<ParentClass> context)
    {
        RuleFor(x => x.ChildList).SetCollectionValidator(new ExtMobileTransactionDataValidator(context.InstanceToValidate));
        return base.Validate(context);
    }
}

public class ChildClass
{
    public int ChildId { get; set; }
    public DateTime DueDate { get; set; }

}

public class ChildClassValidator : AbstractValidator<ChildClass>
{
    public ChildClassValidator(ParentClass parent)
    {
        RuleFor(x => x.ChildId).NotEmpty().WithMessage("Child Id cannot be empty");
        if(parent.ParentId == 1)
        {
            RuleFor(x => x.DueDate).Must(date => date != default(DateTime)).WithMessage("Due date cannot be empty");
        }
    }
}

我能够通过覆盖Validate方法来实现它。

如果子类不会被单独验证，请记住删除子类的Validator属性，否则它将抛出＆＃34;没有定义无参数构造函数＆＃34;错误。
