Question

首先，我已经尝试提出this问题的步骤。

此类Post使用流利的验证方式

public class Post
{
   //...
   public int? LampType { get; set; }
   public int? LampModel { get; set; }
   //...    
}

他的流利验证。很好。

//...
RuleFor(x => x.LampType).NotNull().WithMessage(x => "LampType can't be null");
RuleFor(x => x).Must(p => LampType.Open.ID == p.LampType )
        .When(p => LampModel.NoCover.ID == p.LampModel ).WithMessage(x => "A closed Lamp needs a cover");
RuleFor(x => x).Must(p => LampType.Closed.ID == p.LampType )
        .When(p => LampModel.NoCover.ID != p.LampModel ).WithMessage(x => "A open Lamp can't have a cover");
//...

但是我需要对此进行更新，现在我的帖子可以有多个Lamps，所以我创建了这个：

public class newPost
{
   //...
   public IEnumerable<LampPostModel> Lamps { get; set; }
   //...
}

public class LampPostModel
{
   public int? LampType { get; set; }
   public int? LampModel { get; set; }
}

我已经在PostValidation上尝试过

{
   //...
   RuleFor(x => x.Lamps).SetCollectionValidator(new LampValidator());
   //...
}

这是新的LampValidator

{
   RuleFor(x => x.LampType).NotNull().WithMessage(x => "LampType can't be null");
   RuleFor(x => x).Must(p => LampType.Open.ID == p.LampType )
        .When(p => LampModel.NoCover.ID == p.LampModel ).WithMessage(x => "A closed Lamp needs a cover");
   RuleFor(x => x).Must(p => LampType.Closed.ID == p.LampType )
        .When(p => LampModel.NoCover.ID != p.LampModel ).WithMessage(x => "A open Lamp can't have a cover");
}

但是在进行此更改后，此操作不再起作用。它拒绝第二条规则，即使不应该这样做。似乎验证正在尝试一次测试所有对象，而不是一个一个地

请求是通过类似这样的方式进行的

Lamps[
   {open, nocover},
   {closed, glass}
];

似乎这个问题有点duplicated

我解决了对PostValidator这么做

RuleForEach(x => x.Lamps).SetValidator(new LampPostValidator());

LampValidator

 When(p => p.LampModel== LampType.NoCover.ID, () =>
 {
     RuleFor(p => p).Must(p => p.LampType== LampType.Open.ID);
 });
 When(p => p.LampModel != LampType.NoCover.ID, () =>
 {
     RuleFor(p => p).Must(p => p.LampType == LampType.Closed.ID);
 });

如何使Fluent Validation与对象列表一起使用
