当一个对象从 MarshalByRefObject 派生并且也被标记为 [Serializable] 时会发生什么? [英] what happens when an object derives from MarshalByRefObject and is also marked [Serializable]?

问题描述

我正在处理我的第一个使用 AppDomains 的项目，我想知道当一个对象从 MarshalByRefObject 派生并标记为 [Serializable] 时会发生什么?

I'm working on my first project that uses AppDomains and I'm wondering what happens when an object derives from MarshalByRefObject and is also marked [Serializable]?

例如:

[Serializable]
public class DummyClass: MarshalByRefObject
{

}

推荐答案

它通过引用进行编组，但仍然可以为其他用例进行序列化以进行序列化.有一个实现细节很有趣，值得一提:为远程处理序列化的格式化程序使用 SurrogateSelector 它将为它序列化的任何 MarshalByRefObject 生成代理，因此序列化仍然会导致通过引用编组.其他序列化用途不会有那个 SurrogateSelector，所以不会有那个效果.

It gets marshalled by reference, but can still be serialised for other use-cases for serialisation. There's an implementation detail to this that is interesting enough to be worth noting: The formatter that is serialising for remoting uses a SurrogateSelector that will produce a proxy for any MarshalByRefObject it serialises, hence serialising will still result in marshalling by reference. Other serialisation uses won't have that SurrogateSelector and so won't have that effect.
