问题描述
我知道，私人参数的构造函数的作品，但怎么样的对象，无参数构造函数？
I know that a private parameterless constructor works but what about an object with no parameterless constructors?
我想从第三方库暴露类型，所以我有过的类型定义没有控制权。
I would like to expose types from a third party library so I have no control over the type definitions.
如果有一种方法是什么最容易？例如。我没有什么要创建一个子类。
If there is a way what is the easiest? E.g. I don't what to have to create a sub type.
编辑：
我正在寻找的是类似的定制这里显示的水平：http://msdn.microsoft.com/en-us/magazine/cc163902.aspx虽然我不想不得不求助于流序列化/反序列化。
What I'm looking for is something like the level of customization shown here: http://msdn.microsoft.com/en-us/magazine/cc163902.aspxalthough I don't want to have to resort to streams to serialize/deserialize.
推荐答案
您不能真正使任意类型序列化;在某些情况下（的XmlSerializer ，例如）运行时暴露的选择欺骗的属性。但的DataContractSerializer 不允许这样做。可行的方案：
You can't really make arbitrary types serializable; in some cases (XmlSerializer, for example) the runtime exposes options to spoof the attributes. But DataContractSerializer doesn't allow this. Feasible options:
- 躲在自己的类型的的类的序列化（大量的工作）
- 提供二进制格式化代理人（yeuch）
- 在编写自己的序列化的核心（大量的工作，以得到正确的）
- hide the classes behind your own types that are serializable (lots of work)
- provide binary formatter surrogates (yeuch)
- write your own serialization core (a lot of work to get right)
从本质上讲，如果事情是不是的设计的系列化，很少框架会的让的序列化它。
Essentially, if something isn't designed for serialization, very little of the framework will let you serialize it.
