在实体框架4外显多对多的连接表 [英] Explicit many to many join table in Entity Framework 4

问题描述

在默认情况下EF隐藏着一个多对多的连接表不包含额外的数据比外键连接表。

By default EF hides a many to many join table that does not contain additional data than the foreign keys to the joined tables.

是否有可能告诉EF（和设计师）明确创建的连接表，并使其在code可用？

Is it possible to tell EF (and the designer) to explicitly create the join table and make it usable in code?

感谢

推荐答案

没有EF设计不会为你添加这个实体。如果你想结合表暴露你必须手动删除已创建的关系，并添加结表的实体和两个一对多FK关系。下面是一步引导相关步骤的问题：

No EF designer will not add this entity for you. If you want junction table exposed you must manually delete created relation and add junction table's entity and two one-to-many FK relations. Here are related questions with step by step guide:
