wcf序列化问题，

[mingcsharp]

There was an error while trying to serialize parameter http://www.shiyan56.com:GetProcessLineByIdResult. The InnerException message was 'Type

'System.Data.Entity.DynamicProxies.ProcessLine_376596B54C4C52E7D20DEAE03D96C5BA56D55C89F7D84766AB4831384EBC11E8' with data contract name

'ProcessLine_376596B54C4C52E7D20DEAE03D96C5BA56D55C89F7D84766AB4831384EBC11E8:http://schemas.datacontract.org/2004/07/System.Data.Entity.DynamicProxies' is not expected.
Consider using a DataContractResolver or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list

of known types passed to DataContractSerializer.'. Please see InnerException for more details.
初始wcf，好像是序列化问题，可是不会解决，请大神指点，谢主龙恩!

来一国大神好不？

你的方法中自定义类型吗？ 自定义类型用contract 关键字了吗

[本拉灯]

System.Data.Entity.DynamicProxies ？？ 有用动态类型？？？

EF的ORM对象？微软有提供工具的，打开edmx，右键选添加代码生成项，选联机，输入WCF作为关键字。有个EF X.x xxxx with WCF xxx的，应该就是你需要的东西了。

是不是你要序列化的类中有一个基类的实例? 这样的话, 就得用KnownTypeAttribute指定到底应该使用具体的子类类型.
