如何在实体框架中预先加载子对象的子对象
我有一个 Member 类，它附加了一个 MemberRoles 数组。每个 MemberRoles 都附加有一个 Role 对象。当我去获取我的会员时，我知道我将需要与该会员关联的所有角色对象。我意识到我可以急切地加载 MemberRoles，
var member = context.Members.Include("MemberRoles").SingleOrDefault(....)
我在这里推测（因为我的 DBA 不会授予我运行探查器的权限，grumble *grumble*），但我假设与 MemberRole 对象关联的角色将一旦我开始访问它，就会延迟加载。
当我形成原始查询时，如何立即加载 Role 对象以及 MemberRoles？
I have a Member class that has an array of MemberRoles attached to it. Each of the MemberRoles have a Role object attached to them. When I go to fetch my Member I know that I am going to need all the Role objects associated to the Member. I realize that I can eager load the MemberRoles with
var member = context.Members.Include("MemberRoles").SingleOrDefault(....)
I am speculating here (because my DBA wont give me permission to run profiler, grumble *grumble*) but I assume that the Role associated to the MemberRole object will lazy load once I start accessing it.
How can I eager load the Role object along with the MemberRoles when I form my original query?

尝试
应该立即加载 MemberRoles 和关联的角色。
Try
That should eager-load MemberRoles and the associated Roles.
