[英]What is the best way to cast each item in a LINQ to Entities query to an interface?
I have an entity object 'User' which implements 'IUser': 我有一个实体对象'User'来实现'IUser':
IQueryable<User> users = Db.User;
return users;
But what I actually want to return is: 但我真正想要回归的是:
IQueryable<IUser>
So what is the best way to convert 那么转换的最佳方式是什么?
IQueryable<User>
to 至
IQueryable<IUser>
without actually running the query? 没有实际运行查询? Right now I am doing this but it seems like a hack:
现在我正在做这个,但它似乎是一个黑客:
IQueryable<IUser> users = Db.User.Select<User, IUser>(u => u);
你的“hacky”解决方案对我来说很好。
