RavenDB 转换 - 尝试创建对象列表时抛出异常

Question

我正在尝试运行 RavenDB 转换以将我的文档映射到视图模型，但我运行遇到了这个错误：

Error CS1503 - Argument 1: cannot convert from 'AnonymousType#1'

我不确定为什么不能在这里初始化新的 OfferRate 列表。如何正确地将我的文档模型映射到视图模型？

Offer_ViewModel.cs

public class Offer_ViewModel : AbstractTransformerCreationTask<Offer>
{
    public Offer_ViewModel()
    {
        TransformResults = offers => offers
            .Select(offer => new ViewModels.Offer
            {
                Id = offer.Id,
                MerchantId = offer.MerchantId,
                Title = offer.Title,
                OfferRates = new List<OfferRate>
                {
                  new OfferRate
                  {
                      Type = OfferRateType.Base,
                      Amount = offer.Amount,
                      Percentage = offer.Percentage
                  }  
                },
                Currency = offer.Currency
            });
    }
}

我正在按照此处使用变换器映射到视图模型的指南进行操作：https://ravendb.net/articles/working-with-view-models 但该示例不包括映射聚合对象。

根据上面的评论，将集合更改为数组是可行的。

Offer_ViewModel.cs

public class Offer_ViewModel : AbstractTransformerCreationTask<Offer>
{
    public Offer_ViewModel()
    {
        TransformResults = offers => offers
            .Select(offer => new ViewModels.Offer
            {
                Id = offer.Id,
                MerchantId = offer.MerchantId,
                Title = offer.Title,
                OfferRates = new[]
                {
                  new OfferRate
                  {
                      Type = OfferRateType.Base,
                      Amount = offer.Amount,
                      Percentage = offer.Percentage
                  }  
                },
                Currency = offer.Currency
            });
    }
}
