推荐答案

是的！ 我找到了答案：

Yes! I found the answer:

您当然可以使用code先   映射到一个视图，只是告诉$ C C首先$   这是一个表，它将使用   反对观点，即相同的SQL   会为一个表。显然，如果您   看法是不写那么储蓄   打算如果你尝试更新失败   这是根据在实体值   在视图，但我们只是委托   到数据库中，所以如果你不更新   这些实体，那么你将不会有任何   的问题。

You can certainly use Code First to map to a view, just tell Code First that it's a table and it will use the same SQL against the view that it would for a table. Obviously if your view isn't writeable then saving is going to fail if you try and update values in the entities that are based on the view, but we will just delegate to the database so if you don't update these entities then you won't have any issues.
