NHibernate 多对多参考帮助
我有如下 2 个表（实体）
NewsLetter
-------------------
Id
UserEmail
AgreeToReceiveNewsLetters
DateRegisted
Voucher
-------------------
Id
Code
IsActive
PromoText
CreatedDate
MaxDaysToRedeem
和用于多对多关系的第三个参考表
NewsLetterVoucher
-------------------
Id
NewsLetter_id
Voucher_id
ValidFrom
ValidUntil
DateRedeemed
DateNotified
一切都工作良好 多对多关系的映射工作良好 问题是我想在实体模型中访问存储在引用表（ ValidFrom 、 ValidUntil 等）中的附加信息，
就像
NewsLetter.Voucher[0].ValidFrom
但 ValidFrom 存储在参考表中
我该怎么做
I have 2 tables (entities) like the following
NewsLetter
-------------------
Id
UserEmail
AgreeToReceiveNewsLetters
DateRegisted
Voucher
-------------------
Id
Code
IsActive
PromoText
CreatedDate
MaxDaysToRedeem
and a third reference table for many to many relationhip
NewsLetterVoucher
-------------------
Id
NewsLetter_id
Voucher_id
ValidFrom
ValidUntil
DateRedeemed
DateNotified
All is working good the the mappings for the many to many relationship working good
The problem is that I want to have access in the entity model at the additional information that are stored in the reference table (ValidFrom , ValidUntil etc)
just like
NewsLetter.Voucher[0].ValidFrom
but ValidFrom is stored in the refenece table
How I can do that

有一个类似的问题（ NHibernate：与关系表中的字段的多对多关系）。您需要将关系表映射为类。
There is a similar question (NHibernate: Many-to-many relationship with field in the relationship table). You need to map the relation table as a class.
如果我理解正确的话，我认为这可以解决您的问题。
Fluent nhibernate - 带属性的多对多映射
I think this is a solution to your problem, if I understand it correctly.
