EF4 Cast DynamicProxies到底层对象 [英] EF4 Cast DynamicProxies to underlying object

问题描述

我正在使用具有POCO模板的Entity Framework 4。

我有一个MyObject是动态代理的列表。我想使用XmlSerializer序列化这个列表，但是我不希望它们被序列化为DynamicProxies，而是作为底层的POCO对象。

我知道ContextOptions.ProxyCreationEnabled，但我不想使用它。我只是想知道如何将一个代理对象投放到POCO的底层来序列化。

解决方案

今天遇到同样的问题价值注入器解决它。这很简单：

  var dynamicProxyMember = _repository.FindOne< Member>（m => m.Id = 1）; 
 var member = new Member（）。InjectFrom（dynamicProxyMember）as Member; 
  

I'm using Entity Framework 4 with POCO template.

I have a List where MyObject are dynamic proxies. I want to use the XmlSerializer to serialize this list, but I don't want them serialized as DynamicProxies but as the underlaying POCO object.

I know about ContextOptions.ProxyCreationEnabled, but I do not want to use that. I just want to know how to cast a proxy object to it's underlaying POCO to serialize.

解决方案

Faced the same issue today and used Value Injecter to solve it. It's as simple as:

var dynamicProxyMember = _repository.FindOne<Member>(m=>m.Id = 1);
var member = new Member().InjectFrom(dynamicProxyMember) as Member;
