实体对象的 XML 序列化
我正在尝试将 EF 4.0 对象图序列化为 XML 以通过 WCF 服务传递。过去我曾使用 DTO/POCO 完成此操作（通常用于 JSON 序列化）。在这种情况下，因为我只进行 XML 序列化，所以似乎我应该能够直接序列化实体对象，但是，我遇到了这个难题：
如果我不分离实体，序列化会抛出一个错误，该错误表明对象上下文已被处置（因为它在那时已经被处置，所以这是预期的）。
如果我分离实体，导航属性中加载的所有相关对象都会被删除。
我的期望是，如果我枚举任何链接的实体，然后将该对象与上下文分离，我仍然可以将该关系用于序列化。
所以我的问题是，有没有办法直接序列化实体对象并保留任何加载的导航属性/集合？
谢谢...
I am trying to serialize and EF 4.0 object graph to XML to pass via a WCF service. In the past I have done this with DTO's/POCO's (usually for JSON serialization). In this case since I am only doing XML serialization it seemed that I should just be able to serialize the entity objects directly however, I am running into this conundrum:
If I do not detach the entity, serialization throws an error that the object context has been disposed (because it has at that point so this is expected).
If I detach the entity, any related objects loaded in the navigation properties are dropped.
My expectation was that if I enumerated any linked entities, then detached the object from the context I would still have that relationship available for serialization.
So my question, is there anyway to directly serialize an entity object and retain any loaded navigation properties/collections?
Thanks...

序列化对象时，序列化器将遍历整个对象图。
我认为你应该在序列化之前从实体对象中创建 DTO/POCO。但是，您应该查看 automapper ，它将帮助您将对象从实体转换为 DTO 并返回。
When serializing an object, the serializer will walk the entire object graph.
I think you should make DTO/POCO's from you entity object before serializing. However, you should have a look at automapper which will help you converting your object from entity to DTO and back.
