C# 选择“新建”时需要填充集合的子集合

除了试图用数据填充子集合的区域外，我的Linq查询中的所有内容都正常工作。任何引用频道信息的东西

ChannelInfo确实出现在Intellisense中，因此它被识别为新OfferType的属性。我的ChannelInfo设置器的右侧也可以在intellisense中识别和访问。如果可能的话，我真的需要创建新的OfferType对象。我是否可以引用子连接ChannelInfo以使此查询正常工作

IEnumerable<OfferType> list = (from offerCatType in offerRes.OfferCategory  <=---- OfferCategoryType objects
                               where offerCatType.type == Type
                               from offers in offerCatType.Offer  <=--- OfferType objects
                               where Convert.ToDateTime(offers.startDate) > MonthYear && Convert.ToDateTime(offers.endDate) < MonthYear
                                     select new OfferType
                                     { 
                                         name = offers.name,
                                         description = offers.description, 
                                         startDate = offers.startDate, 
                                         endDate = offers.endDate, 
                                         ChannelInfo.refClickThroughLink = offers.ChannelInfo.refClickThroughLink,
                                         ChannelInfo.refId = offers.ChannelInfo.refId,
                                         ChannelInfo.refLink = offers.ChannelInfo.refLink 
                                     }
                                 );

请原谅语法错误。但是，您必须重新设置ChannelInfo类。

谢谢。当然，我尝试了不同的版本！

select new OfferType
{ 
   name = offers.name,
   description = offers.description, 
   startDate = offers.startDate, 
   endDate = offers.endDate, 
   ChannelInfo = 
   new ChannelInfo 
   { 
      refClickThroughLink = offers.ChannelInfo.refClickThroughLink,
      refId = offers.ChannelInfo.refId,
      refLink = offers.ChannelInfo.refLink 
   };
}
